BT’s Rochdale Data Center uses curtains to separate the hot and cold aisles, thereby reducing the amount of hot air that mixes with cold air from the plenum floor and dramatically increasing cooling efficiency. Each cabinet is also fitted with blanking panel to ensure that the only path for cold air to pass is via a piece of equipment.


1.Background
  • Server farms—also known as data centers—are the enormous housing facilities that make the internet possible. A single Google data center, in Oregon consumes as much energy as a city of 200,000. That's because servers not only have to be on 24/7, they need to be kept cool 24/7. Up to 50 percent of the power they use is just to keep them from melting down. Overall, the internet is responsible for 2% of global carbon emissions, about the same as the aviation industry. A single Data Center can consume 30 -100 MW of electric power. Data Center energy demand may be larger than some small utilities’ capacity.
  • According to the DOE, data centers are responsible for 3 percent of U.S. energy consumption, and growing, and a typical 125,000-SF data center consumes $3 million worth of energy per year. U.S. data center power use is expected to double by 2015 to add up to $7.4 billion in annual power bills, the EPA says. That could drive a fourfold increase in the green data center market to some $41.4 billion by 2015, Pike Research estimates.
  • Data centers are becoming one of the single largest industrial energy users, consuming 61.4 billion kilowatt-hours annually in the U.S. alone, and producing more than 43 million tons of CO2 each year. In addition to financial and capacity considerations, reducing data center energy use has become a priority for organizations seeking to reduce their environmental footprint.
  • The cost of powering and cooling servers in the United States alone was expected to grow from $4.5 billion in 2006 to $7.4 billion in 2011, according to the Environmental Protection Agency (EPA).  However, thanks to the recession and energy efficiency technology, data centers consumed less electricity than expected between 2005 and 2010, according to a report by researcher Jonathan Koomey While data center electricity consumption doubled between 2000 and 2005, the electricity consumption of data centers grew by just 56 percent globally between 2005 and 2010, and specifically grew by 36 percent in the U.S. over that time period.


    The results are surprising because researchers, including the EPA, had predicted that the electricity consumption of data centers would again double between 2005 and 2010, following the trend of the previous five years. But the doubling trend was cut short, partly because of proactive reasons by data center operators, and partly because of the overall macroeconomic downturn.
  • Data centers consume around 2.5 percent of the power in Northern California and the total consumed by data centers in the area has been growing by 15 percent a year.
  • Another impact of higher energy densities is that server hardware is no longer the primary cost component of a data center. The purchase price of a new (1U) server has been exceeded by the capital cost of power and cooling infrastructure to support that server. And this will soon be exceeded by the lifetime energy costs for that server alone. This represents a significant shift in data center economics that seriously challenges conventional cooling strategies.


Analysis of a typical 5000-square-foot data center shows that demand-side computing equipment accounts for 52 percent of energy usage and supply-side systems account for 48 percent.


2. Acronyms/Definitions
  1. 80 Plus - An electric utility-funded incentive program to integrate more energy-efficient power supplies into desktop computers and servers. Participating utilities and energy efficiency organizations across North America have contributed over $5 million of incentives to help the computer industry transition to 80 PLUS certified power supplies

  2. ASE - Air Side Economizer - Can save energy in buildings by using cool outside air as a means of cooling the indoor space. When the enthalpy of the outside air is less than the enthalpy of the recirculated air, conditioning the outside air is more energy efficient than conditioning recirculated air. When the outside air is both sufficiently cool and sufficiently dry (depending on the climate) the amount of enthalpy in the air is acceptable to the control, no additional conditioning of it is needed; this portion of the air-side economizer control scheme is called free cooling.

    Google turns to free cooling, or outside air, whenever possible:


  3. Blade Servers – Stripped down computer servers with a modular design optimized to minimize the use of physical space. Whereas a standard rack-mount server can function with a power cord and network cable, blade servers have many components removed to save space, minimize power consumption. The blade's shared power and cooling means that it does not generate as much heat as traditional servers. Newer blade-enclosure designs feature high-speed, adjustable fans and control logic that tune the cooling to the system's requirements, or even liquid cooling-systems. At the same time, the increased density of blade-server configurations can still result in higher overall demands for cooling with racks populated at over 50% full.
  4. Blanking Panels - Minimize recirculation of hot air. Each cabinet is fitted with blanking panel to ensure that the only path for cold air to pass is via a piece of equipment. Missing cabinets and missing equipment offers an alternative route for airflow that causes hot and cold air to mix reducing air handling
    efficiency.

  5. Carbon Intensity Per Unit of Data. - Content delivery network leader Akamai has been reporting the carbon emissions related to its cloud computing-based services in the metric of “CO2 per megabytes of data delivered.” Establishing this metric enables Akamai to compare cloud computing energy usage across the industry, and Akamai is also in the process of making this metric available on a monthly basis to its customers. Greenpeace has lauded Akamai for its transparency and reporting of this metric, and gave Akamai the highest grade for “transparency,” out of 10 giant Internet players like Google, Apple and Facebook.

  6. CFD - Computational Fluid Dynamics - Used to identify inefficiencies and optimize data center airflow.

    How Google manages air flow:
  7. CRAC - Computer Room Air Conditioner

  8. CSCI - Climate Savers Computing Initiative - An effort to reduce the electric power consumption of PCs in active and inactive states.

  9. CUE - Carbon Usage Effectiveness - Similar to GPUE - Also created by Green Grid, CUE is a ratio of the total carbon emissions due to the energy consumption of the data center (the same one used for the PUE) compared to the energy consumption of the data center’s servers and IT equipment (the same one used for PUE). The metric is expressed in kilograms of carbon dioxide (kgCO2eq) per kilowatt-hour (kWh), and if a data center is 100-percent powered by clean energy, it will have a CUE of zero. The CUE could one day be a particularly important metric if there is a global price on carbon.

  10. DCIE - Data Center Infrastructure Efficiency - The reciprocal of PUE and is expressed as a percentage that improves as it approaches 100%. It is Energy for IT Equipment/Total Energy for the Data Center

  11. Data Deduplication - Whenever you send out a press release or goofy office party photo, that document gets duplicated several times. There is a tremendous amount of promise for reducing power through reducing storage. Saves up to 95% for full back ups; 25% to 55% for most data sets.
  12. Double Conversion UPS – Used in most datacenters, these systems convert incoming power to DC and then back to AC within the UPS. This enables the UPS to generate a clean, consistent waveform for IT equipment and effectively isolates IT equipment from the power source. UPS systems that don’t convert the incoming power (line interactive or passive standby systems) can operate at higher efficiencies because of the losses associated with the conversion process. However, these systems may compromise equipment protection because they do not fully condition incoming power. Care must be taken to ensure reductions in energy consumption are not achieved at the cost of reduced equipment availability.

  13. DPM - Distributed Power Management - Migrates machines off of underutilized hosts in an effort to put the hosts into standby mode to conserve energy.

  14. EPEAT - Electronic Product Environmental Assessment Tool - Created by the Green Electronics Council to assist in the purchase of "green" computing systems. The Council evaluates computing equipment on 28 criteria that measure a product's efficiency and sustainability attributes. On 2007-01-24, President Bush issued Executive Order 13423, which requires all United States Federal agencies to use EPEAT when purchasing computer systems.

  15. GPUE - Similar to CUE - Green Power usage effectiveness (GPUE) is a proposed measurement of both how much sustainable energy a computer data center uses, its carbon footprint per usable Kwh and how efficiently it uses its power; specifically, how much of the power is actually used by the computing equipment (in contrast to cooling and other overhead). It is an addition to the PUE definition and was first proposed by Greenqloud. GPUE is a way to “weigh” the PUE to better see which data centers are truly green in the sense that they indirectly cause the least amount of CO2 to be emitted by their use of sustainable or unsustainable energy sources.

    GPUE = G x PUEx (for inline comparison of data centers) or = G @ PUEx (a better display and for co2 emission calculations) G = Weighed Sum of energy sources and their lifecycle KG CO2/KWh

  16. Hot-Aisle/Cold-Aisle Configuration - The arrangement of rack computer cabinets within the data center so that hot and cold air are separated into separate aisles thereby improving cooling efficiency. Data Centers typically have a raised floor or plenum floor arrangement where cold air is delivered under pressure, causing it to escape from every opening. Typically a certain number of the tiles in the floor are perforated or integrate an opening vent. Hot air rises to the top of the computer room, where it is captured by Computer Room Air Conditioners (CRAC) and chilled to be pumped back under the floor. An efficient data center ensures that as much of the cold air is drawn across hot computer parts as possible and that hot and cold air are not allowed to mix.

  17. Hot-Aisle/Cold-Aisle Containment – A variation on the above configuration that isolates hot and cold air streams so they don’t mix with one another and cause energy inefficiencies.

  18. Hypervisor - Also called virtual machine monitor (VMM) - Allows multiple operating systems to run concurrently on a host computer— a feature called hardware virtualization. The hypervisor presents the guest operating systems with a virtual platform and monitors the execution of the guest operating systems. In that way, multiple operating systems, including multiple instances of the same operating system, can share hardware resources.

  19. PAR4 - A metric developed by startup Power Assure that measures server power consumption in different ways, including monitoring idle power, peak power, total utilization power, and “transactions-per-watt.” Essentially, PAR4 enables servers of different makes, models and generations to be compared to one another in terms of energy efficiency. That type of detailed measurement is mostly lacking for servers today. Power Assure says PAR4 is already gaining acceptance from big players like Intel, Dell and Cisco, which have been working to incorporate PAR4 into their systems
    .
  20. PSU – Power Supply Unit - (aka PDU - Power Distriibution Unit) Efficiency varies widely. Desktop PSU’s are generally 70–75% efficient dissipating the remaining energy as heat. An industry initiative called 80 PLUS certifies PSUs that are at least 80% efficient; typically these models are drop-in replacements for older, less efficient PSUs of the same form factor. As of July 20, 2007, all new Energy Star 4.0-certified desktop PSUs must be at least 80% efficient
    .
  21. PUE Ratio - Power Usage Effectiveness - A metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1. Uptime estimates most facilities could achieve 1.6 PUE using the most efficient equipment and best practices. PUE was developed by the Green Grid provides a measure of infrastructure efficiency, but not total facility efficiency.

    Data centers with legacy cooling infrastructures average a PUE of 2.25, according to the Uptime Institute. With the introduction of next-generation CRACs, AHUs and chiller systems, PUEs can be reduced to 1.25 without sacrificing temperature or humidity control. To put that in a financial context, lowering a PUE from 2.25 to 1.25 can slash spending from $0.44 per ton-hour for cooling to less than $0.05 per ton-hour.

  22. How Google looks at PUE
  23. RH – Relative Humidity - Data Center air should contain the proper amount of water vapor to maximize the availability of computing equipment. Air containing too much or too little water vapor can cause failures. At the outer extremities of RH, we can see condensation forming on equipment, or at the other end, static electricity buildup and discharge.

  24. RSE - Refrigerant Side Economizing - Can reduce refrigeration compressor energy by up to 100 percent. By deploying RSE solutions directly in the return air based on the outside wet-bulb temperature, rather than dry bulb temperature relied upon by ASE, economizing hours can be increased by as much as 50 percent, as compared to airside economizing and typical waterside economizing.

  25. Server Virtualization – A method of partitioning a physical server computer into multiple servers such that each has the appearance and capabilities of running on its own dedicated machine. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted.

  26. SPEC - Standard Performance Evaluation Corporation - A non-profit corporation formed to establish, maintain and endorse a standardized set of relevant benchmarks that can be applied to the newest generation of high-performance computers. SPEC develops benchmark suites and also reviews and publishes submitted results from our member organizations and other benchmark licensees. SPEC score being used as the server performance measure.

  27. TDP – Thermal Design Power - The maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat without exceeding the maximum junction temperature for the computer chip. In the absence of a true standard measure of processor efficiency comparable to the U.S. Department of Transportation fuel efficiency standard for automobiles, TDP serves as a proxy for server power consumption. The typical TDP of processors in use today is between 80 and 103 Watts (91W average).

  28. Thin Provisioning - A way to cut the power associated with storage. Most corporations reserve way too much storage for their needs. Reducing that number can potentially cut down power going to air conditioners and storage devices.

  29. UPS - Uninterruptible Power Suply - An electrical apparatus that provides emergency power to a load when the input power source, typically the utility mains, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide instantaneous or near-instantaneous protection from input power interruptions by means of one or more attached batteries and associated electronic circuitry for low power users, and or by means of diesel generators and flywheels for high power users. The on-battery runtime of most uninterruptible power sources is relatively short—5–15 minutes being typical for smaller units—but sufficient to allow time to bring an auxiliary power source on line, or to properly shut down the protected equipment. Efficiency varies widely

  30. VDI - Virtual Desktop Infrastructure - (Sometimes Virtual Desktop Interface) - The server computing model enabling desktop virtualization, encompassing the hardware and software systems required to support the virtualized environment

  31. WUE - Water Usage Effectiveness - Also created by Green Grid,Calculates how efficiently a data center is using water. It is a ratio of the annual water usage to how much energy is being consumed by the IT equipment and servers, and is expressed in liters/kilowatt-hour (L/kWh). Like CUE, the ideal value of WUE is zero, meaning no water was used to operate the data center.


3. Business Case
  • The potential savings from more efficient data centers is enormous. 20%-40% savings are typically possible with aggressive strategies producing better than 50% savings. Paybacks are short - one to three years are common. However, today, most centers don't know if they are good or bad.
  • Facilities operating at high utilization rates throughout a 24-hour day will want to focus initial efforts on sourcing IT equipment with low power processors and high efficiency power supplies.
  • Facilities that experience predictable peaks in activity may achieve the greatest benefit from power management technology.


Power supply efficiency can vary significantly depending on load and power supplies are often sized for a load that exceeds the maximum server configuration. Sizing power supplies closer to actual load is another opportunity to increase efficiency. Notice that the maximum configuration is about 80 %of the n ameplate rating and the typical configuration is 67% of the nameplate rating.

4. Energy Saving Strategies
  1. Liquid Cooling - A number of vendors offer solutions that deliver cold water cooling either through coils fitted to the rear doors of computer cabinets or through cold plates attached directly to the CPU chips. Direct chip attachment has the advantage of reducing the case temperature so much that the CPUs can be clocked at a very high rate, much higher than that which can be supported with air cooling. While it might seem that water and electronics don’t mix well, experienced data center managers know that water is the main medium that is used in Computer Room Air Conditioners (CRAC) units to cool the raised floor area. Bringing water closer to the CPU core can improve the efficiency of heat transfer by as much as 4000 times.
    • One basic approach to get cold water closer to the case or heat-sinks of the hottest components (generally the CPUs) uses cold plates physically bolted to the CPUs with centrally delivered chilled water channeled through them. This removes heat efficiently but is mainly targeted at getting the case temperature down so that the chips can be over-clocked reliably delivering more performance for the same basic silicon.
    • The second approach uses cold water delivery to coils in a rear door. IBM’s Rear Door Heat eXchanger is 4 inches thick and weighs in at a hefty 70 lbs. IBM claim that the door can absorb as much as 50% of the heat coming from the server rack.
  2. Efficient Processors- For a price premium, processor manufacturers provide lower voltage versions of their processors that consumes on average 30 Watts less than standard processors. Independent research studies show these lower power processors deliver the same performance as higher power models.
  3. Efficient Power Supplies - Many of the server power supplies in use today are operating at efficiencies below what is currently available. The EPA estimated the average efficiency of installed server power supplies at 72 percent in 2005. Best-in-class power supplies are available today that deliver efficiency of 90 percent. As with other data center systems, server power supply efficiency varies depending on load. Some power supplies perform better at partial loads than others and this is particularly important in dual-corded devices where power supply utilization can average less than 30 percent.

    Google saves $30 a year in energy costs per server just by joining the battery to the server, instead of using a centralized UPS system.

  4. Power Management Software - Data centers are sized for peak conditions that may rarely exist. In a typical business data center, daily demand progressively increases from about 5 a.m. to 11 a.m. and then begins to drop again at 5 p.m. Server power consumption remains relatively high as server load decreases In idle mode, most servers consume between 70 and 85 percent of full operational power. Consequently, a facility operating at just 20 percent capacity may use 80 percent of the energy as the same facility operating at 100 percent capacity. Server processors have power management features built-in that can reduce power when the processor is idle. Too often these features are disabled because of concerns regarding response time; however, this decision may need to be reevaluated in light of the significant savings this technology can enable.
  5. Blade Servers - Many organizations have implemented blade servers to meet processing requirements and improve server management. While the move to blade servers is typically not driven by energy considerations, blade servers can play a role in energy consumption. Blade servers consume about 10 percent less power than equivalent rack mount servers because multiple servers share common power supplies, cooling fans and other components.
  6. Server Virtualization - As server technologies are optimized, virtualization is increasingly being deployed to increase server utilization and reduce the number of servers required.
  7. Cooling Best Practices - Most data centers have implemented some best practices, such as the hot-aisle/cold-aisle rack arrangement. Potential exists in sealing gaps in floors, using blanking panels in open spaces in racks, and avoiding mixing of hot and cold air. Temperatures in the cold aisle may be able to be raised if current temperatures are below 68° F. Chilled water temperatures can often be raised from 45° F to 50° F.
  8. 415V AC Power Distribution - In most data centers, the UPS facility provides power at 480V, which is then stepped down via a transformer, with accompanying losses, to 208V in the power distribution system. These stepdown losses can be eliminated by converting UPS output power to 415V. The 415V three-phase input provides 240V single-phase, line-to-neutral input directly to the server.. This higher voltage not only eliminates stepdown losses but also enables an increase in server power supply efficiency. Servers and other IT equipment can handle 240V AC input without any issues.
  9. Variable Capacity Cooling - Data center systems are sized to handle peak loads, which rarely exist. Consequently, operating efficiency at full load is often not a good indication of actual operating efficiency. Newer technologies, such as Digital Scroll compressors and variable frequency drives in computer room air conditioners (CRACs), allow high efficiencies to be maintained at partial loads. Digital scroll compressors allow the capacity of room air conditioners to be matched exactly to room conditions without turning compressors on and off. Typically, CRAC fans run at a constant speed and deliver a constant volume of air flow. Converting these fans to variable frequency drive fans allows fan speed and power draw to be reduced as load decreases. Fan power is directly proportional to the cube of fan rpm and a 20 percent reduction in fan speed provides almost 50 percent savings in fan power consumption. These drives are available in retrofit kits that make it easy to upgrade existing CRACs with a payback of less than one year.
  10. High Density Supplemental Cooling - Traditional room-cooling systems have proven very effective at maintaining a safe, controlled environment for IT equipment. However, optimizing data center energy efficiency requires moving from traditional data center densities (2 to 3 kW per rack) to an environment that can support much higher densities (in excess of 30 kW). This requires implementing an approach to cooling that shifts some of the cooling load from traditional CRAC units to supplemental cooling units. Supplemental cooling units are mounted above or alongside equipment racks and pull hot air directly from the hot aisle and deliver cold air to the cold aisle. Supplemental cooling units can reduce cooling costs by 30 percent compared to traditional approaches to cooling. These savings are achieved because supplemental cooling brings cooling closer to the source of heat, reducing the fan power required to move air. They also use more efficient heat exchangers and deliver only sensible cooling, which is ideal for the dry heat generated by electronic equipment. Refrigerant is delivered to the supplemental cooling modules through an overhead piping system, which, once installed, allows cooling modules to be easily added or relocated as the environment changes.
  11. Monitoring and Optimization - One of the consequences of rising equipment densities has been increased diversity within the data center. Rack densities are rarely uniform across a facility and this can create cooling inefficiencies if monitoring and optimization is not implemented. Room cooling units on one side of a facility may be humidifying the environment based on local conditions while units on the opposite side of the facility are dehumidifying. Cooling control systems can monitor conditions across the data center and coordinate the activities of multiple units to prevent conflicts and increase teamwork.
  12. Consolidated Data Storage – Move from direct attached storage to network attached storage. Also, faster disks consume more power so it is worthwhile to reorganizing data so that less frequently used data is on slower archival drives.
  13. Economizers - Economizers allow outside air to be used to support data center cooling during colder months, creating opportunities for free cooling. With today’s high-density computing environment, economizers can be cost effective in many more locations than might be expected.
  14. Monitor Generation Losses - Monitor and reduce parasitic losses from generators, exterior lighting and perimeter access control. For a 1 MW load, generator losses of 20 kW to 50 kW have been measured.
  15. Direct Current - Every power conversion (AC-DC, DC-AC, AC-AC) loses some energy and creates heat. Computer equipment uses and Solar creates Direct Current.


Using the model of a 5,000-square-foot data center consuming 1127 kW of power, the above actions work together to produce a 585 kW reduction in energy use.


5. Benefits
  • Reduce Data Center Capital Expense - Cutting wasted watts allows data centers to expand IT capacity within their existing walls and avoid building or buying new data center space.
  • Liquid Cooling Benefits
    • No refrigeration needed, even in the hottest climates free air cooling could be used as input liquid temperatures of 130o F could be used
    • Waste heat could be delivered at useful temperatures like 160o F
    • Pump energy could be minimized enabling PUE levels of 1.05 or better to be achieved
    • Data Centers could be silent as there would be no need for fans

    • Better CRAC unit efficiency
    • Lower air handling energy (larger more efficient fan units)
    • Significantly better Power Usage Efficiency
    • More cores per KW of electricity
    • The front and back of the servers (blades) are unencumbered by the need for cooling fans and slots freeing space for connectors and indicators
    • There is no front and back so servers (blades) can be fitted into both doubling the number of cores per U of rack space


6. Risks/Issues
  • Consumer Backlash - In April 2011 Greenpeace called out a number of top cloud computing companies that have fast-growing electricity needs for their lack of transparency and bad energy choices. The report also cites the positive contributions of the cloud and lists recommendations for how IT companies can green their act.
    Source: Greenpeace April 2011

  • Utilization - Data Center Servers are generally utilized at an average rate of 10%. The power draw on a server is very steap. A server may draw 225W when 100% utilized and only drop to 200W when idle. There is an opportunity to power down more efficiently. Virtualization can reduce the number of servers and increase utilization.

  • Power Availability - According to a Fall 2007 Survey of the Data Center Users Group (DCUG), an influential group of data center managers, power limitations were cited as the primary factor limiting growth by 46 percent of respondents, more than any other factor.

  • Misaligned Incentives - Except for the largest utility sized data centers, IT managers rarely have budgetary responsibility for facilities and energy use.

  • Critical Systems– Data Center availability can be critical to the organization’s health and trumps energy savings if there is a problem.

  • Retrofitting Legacy Data Centers - How do we get more cooling capacity from sites we built a decade ago for low power density applications? One of the biggest problems is that everyone is trying to work against a basic law of physics; hot air rises, and cold air falls. A conventional data centre is designed to support servers that pull air in from the front and blow it out the back of the cabinet. So common sense tells us that computers at the top of the cabinet don’t get as much cold air as computers at the bottom.

  • Inaccurate Server Specs - Many server makers tend to publish specifications for their servers that overstate how much power they need at a maximum power draw. There’s a reason for this: Server makers don’t want data center operators to try to run too many servers off one rack or power supply, only to see a surge in power use blow circuits or damage equipment. That’s how data center managers get fired. But overestimating energy consumption for servers also means data centers are often under-utilizing their available power per rack, row or section of the data center.

  • Over Cooling - According to a server expert at Intel, most data center managers keep their facilities much too cold -- as much as 15 percent too cold. In an article by Rik Myslewski published in The Register, Dylan Larson, Intel's director of server platform technology initiatives, explained that keeping data centers in the low 70s and high 60s leads to a significant amount of excess cooling, and wasted energy. The ideal temperature, per Larson as well as ASHRAE, is a balmy 80 degrees.
    Google suggests running data centers at hotter temperatures, like 80 degrees:

  • Immature Computing Efficiency Metrics – There is a need to define universally accepted metrics for processor, server and data center efficiency There have been tremendous technology advances in server processors in the last decade. Until 2005, higher processor performance was linked with higher clock speeds and hotter chips consuming more power. Recent advances in multi-core technology have driven performance increases by using more computing cores operating at relatively lesser clock speeds, which reduces power consumption. Today processor manufacturers offer a range of server processors from which a customer needs to select the right processor for the given application. What is lacking is an easy to understand and easy to use measure, such as the miles-per-gallon automotive fuel efficiency ratings, that can help buyers select the ideal processor for a given load. The performance per Watt metric is evolving gradually with SPEC score being used as the server performance measure, but more work is needed. This same philosophy could be applied to the facility level. An industry standard of data center efficiency that measures performance per Watt of energy used would be extremely beneficial in measuring the progress of data center optimization efforts. IT management needs to work with IT equipment and infrastructure manufacturers to develop the miles-per-gallon equivalent for both systems and facilities.

  • Inefficiency - Legacy equipment is inefficient. Infrastructure is typically oversized for much of its life because power requirements are overstated.
    • Multiple Power Conversion - Each time power is converted between AC and DC some power is converted to heat which must then be removed. The efficiency of UPS's, Transformers and PDU's (with transformers) varies.

  • Hot Aisle/Cold Aisle Issues
    • Fire Codes - When isolating those air streams, data centers can leave themselves vulnerable to violating fire codes that require detection and prevention devices throughout the room. If the hot aisle exceeds 110 degrees, you could actually exceed the National Electric Code standards. If you have plastic sheets over your racks and don’t have sprinklers in the contained area, how can a potential fire be squelched?
    • Employee Comfort - It isn’t comfortable for technicians to work on equipment in very hot conditions

  • Liquid Cooling Issues
    • Redundancy is much more problematic and expensive with liquid than air. An extra CRAC or two in the data center can be used as a backup for a fairly wide expanse of racks. How do you get cooling redundancy for a 20KW liquid cooled rack? Not impossible but very expensive.
    • Cost of equipment is significantly higher, at least today. Rather than a Single CRAC servicing 20-30 racks, the liquid solutions are most always one per rack. Even with densification of the racks, the costs of liquid cooling equipment inside the data center are many times that of air.
    • Space Issues - How many data centers really have a "Space" problem? With the 6-10KW racks of the typical data center replacing the traditional 1-3KW racks, very few sites run out of space before they are up against serious power and plant cooling constraints. 6-10KW is easily handled with traditional cooling solutions and proper airflow design.


7. Success Criteria
  1. Measure PUE -Know your data center's efficiency performance by measuring energy consumption and frequent PUE monitoring.
  2. More Sophisticated Power Management - While enabling power management features provides tremendous savings, IT management often prefers to stay away from this technology as the impact on availability is not clearly established. As more tools become available to manage power management features, and data is available to ensure that availability is not impacted, we should see this technology gain market acceptance. More sophisticated controls that would allow these features to be enabled only during periods of low utilization, or turned off when critical applications are being processed, would eliminate much of the resistance to using power management.
  3. Matching Power Supply Capacity to Server Configuration - Server manufacturers tend to oversize power supplies to accommodate the maximum configuration of a particular server. Some users may be willing to pay an efficiency penalty for the flexibility to more easily upgrade, but many would prefer a choice between a power supply sized for a standard configuration and one sized for maximum configuration. Server manufacturers should consider making these options available and users need to be educated about the impact power supply size has on energy consumption.
  4. Design for High Density - A perception persists that high-density environments are more expensive than simply spreading the load over a larger space. High density environments employing blade and virtualized servers are actually economical as they drive down energy costs and remove constraints to growth, often delaying or eliminating the need to build new facilities.
  5. Integrate Measurement and Control - Data that can be easily collected from IT systems and the racks that support them has yet to be effectively integrated with support systems controls. This level of integration would allow IT systems, applications and support systems to be more effectively managed based on actual conditions at the IT equipment level.
  6. Location, Location, Location - Ideally a data center ought to be located in a cold place with plenty of electrical power and close to a consumer (market garden, manufacturing process, swimming pool complex) that can use the warm water or air that is a byproduct of operations. It should not be close to incineration plants or other industrial processes that expel foul contamination or dust into the air. Trees that give off sap are also best kept a reasonable distance away. Being close to a source of cold water like a large lake, or a fast flowing river can make cooling much less costly. Being close to multiple sources of high capacity network connections is also pretty essential.
  7. Manage Air Flow - Good air flow management is a fundamental to efficient data center operation. Start with minimizing hot and cold air mixing and eliminate hot spots.
  8. Adjust the Thermostat - Raising the cold aisle temperature will minimize chiller energy use. Don't try to run at 70F in the cold aisle, try to run at 80F; virtually all equipment manufacturers allow this.
  9. Use Free Cooling - Water or air-side economizers can greatly improve energy efficiency.
  10. Optimize Power Distribution - Whenever possible use high-efficiency transformers and UPS systems. 415V power distribution is used commonly in Europe, but UPS systems that easily support this architecture are not readily available in the United States. Manufacturers of critical power equipment should provide the 415V output as an option on UPS systems and can do more to educate their customers regarding high-voltage power distribution.
  11. Buy Efficient Servers - Specify high-efficient servers and data storage systems. The Climate Savers Computing Initiative offers resources to identify power-efficient servers.
  12. Improved Sleep Mode - Engineers must architect networks that wake up and go to sleep faster. Network designers must challenge the “always on” assumption for desktops and appliances. Networks will require significant improvements in scheduling and forecasting of work to allow more machines to go to sleep at any given moment.

The IBM lab in Zurich has developed a new cooling technology by attaching small water pipes to the surface of each computer chip in a server. Water is piped within microns of the chip to cool it down, then the waste water is piped out hot enough to make a cup of Ramen, heat a building, or keep a swimming pool warm. The new cooling system will reduce the carbon footprint of servers by 85 percent and the energy use by 40 percent.

    REDD - Reducing Emissions from Deforestation and Forest Degradation

    One of the most controversial issues in the climate change debate. The basic concept is simple: governments, companies or forest owners in the South should be rewarded for keeping their forests instead of cutting them down. The devil, as always, is in the details.

    1.Background
    • Deforestation and forest degradation, through agricultural expansion, conversion to pastureland, infrastructure development, destructive logging, fires etc., account for nearly 20% of global greenhouse gas emissions, more than the entire global transportation sector and second only to the energy sector. IPCC estimates that land-use change conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere. For comparison, emissions from fossil fuel combustion and cement production amount to 6.3 ± 0.6 Gt carbon per year.

    • In order to constrain the impacts of climate change within limits that society will reasonably be able to tolerate, the global average temperatures must be stabilized within two degrees Celsius. This will be practically impossible to achieve without reducing emissions from the forest sector, in addition to other mitigation actions.

    • In the 1997 global climate agreement, the Kyoto Protocol, policies related to deforestation and degradation were excluded due to the complexity of measurements and monitoring for the diverse ecosystems and land use changes and concerns about countries losing sovereignty over
      their natural resources.

      At the 2007 Bali UNFCCC meeting (COP-13), an agreement was reached on “the urgent need to take further meaningful action to reduce emissions from deforestation and forest degradation”

    • The 2010 Cancun Conference (COP-16) recognized the much broader contribution of forest-related activities in efforts to limit climate change. Specific recognition was given to the reduction of deforestation and degradation through such initiatives as REDD and REDD+. This means that forests will be included in any future agreement with the possibility of generating international credits from these activities.

      Measurement of forest carbon will occur at the national level, thus enabling programmatic approaches. This measure is expected to encourage greater geographic diversification

    • Reducing Emissions from Deforestation and Forest Degradation (REDD) is an effort to create a financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. “REDD+” goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks.

      It is predicted that financial flows for greenhouse gas emission reductions from REDD+ could reach up to US$30 billion a year. This significant North-South flow of funds could reward a meaningful reduction of carbon emissions and could also support new, pro-poor development, help conserve biodiversity and secure vital ecosystem services
      .
    • Governments in developing countries with tropical forests hope to be able to reduce their deforestation rates without being financially disadvantaged, through a system of positive financial incentives. There are now a number of other proposals on the table as well, and some of these suggest financial mechanisms other than carbon credits with which to fund a REDD mechanism. All are also based on the idea that Northern countries are responsible for providing financial support to Southern countries’ climate change mitigation and adaptation activities; and seek to generate a significant level of compensation or economic incentive to outweigh the income generated through deforestation.

    2. Acronyms/Definitions

    UNFCCC Glossary

    1. Afforestation - The process of creating forests on land that was previously unforested, typically for longer than a generation. In some places, forests need help to reestablish themselves because of environmental factors. For example, in arid zones, once forest cover is destroyed, the land may dry and become inhospitable to new tree growth. Other factors include overgrazing by livestock, especially animals such as goats,cows, and over-harvesting of forest resources. Together these may lead to desertification and the loss of topsoil; without soil, forests cannot grow until the long process of soil creation has been completed - if erosion allows this. In some tropical areas, forest cover removal may result in a duricrust or duripan that effectively seal off the soil to water penetration and root growth. Mechanical breaking up of duripans or duricrusts is necessary, careful and continued watering may be essential, and special protection, such as fencing, may be needed.

    2. A/R Project - CDM Afforestation and Reforestation Project. Deforestation, particularly in Brazil, Indonesia and parts of Africa, account for about 20% of greenhouse gas emissions. Deforestation can be avoided either by paying directly for forest preservation, or by using offset funds to provide substitutes for forest-based products.

      CDM project activities can be categorized into “Emission reduction project” and “Sink project”. Sink projects are to absorb carbon through afforestation or reforestation activities.

    3. CCB Standards - Can be applied throughout the life of the project to evaluate the social and environmental impacts of land based carbon projects. The CCB Standards can be combined with many other standards, such as the Clean Development Mechanism (CDM), or the Voluntary Carbon Standard (VCS). The CCB Standards provide a basis for evaluating a project’s social and environmental impact, while the carbon accounting standard enables verification and registration of quantified greenhouse gas emissions reductions or removals. Using both standards together enables investors to select carbon credits with additional benefits, while screening out projects with unacceptable social and environmental impacts.

      The standards comprise fourteen required criteria and three optional "Gold Level” criteria. Once a project has been designed, a third-party evaluator will use indicators to determine if individual criteria are satisfied.

      As of December 2010, a total of 28 projects have completed validation, and 23 other projects have initiated the validation process. Of these 51 projects, 41 are in developing countries and represent exciting initiatives to stimulate investment, jobs, biodiversity conservation and many other social and environmental benefits. At least 100 projects are planning to use the standards, representing over 7 million ha of conservation and over 370,000 ha of restoration of native forests with total estimated annual emissions reductions of over 12.7 million tons annually.

    4. CDM - Clean Development Mechanism - Allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to a meet a part of their emission reduction targets under the Kyoto Protocol. The mechanism stimulates sustainable development and emission reductions, while giving industrialized countries some flexibility in how they meet their emission reduction limitation targets.

    5. CER - Certified Emission Reductions - A type of emissions unit (or carbon credits) issued by the Clean Development Mechanism (CDM) Executive Board for emission reductions achieved by CDM projects.

    6. HWP - Harvested Wood Products - According to the IPCC good practice guidance (2003) include wood and paper products. It does not include carbon in harvested trees that are left at harvest sites. Emissions and removals associated with forest harvesting and the oxidation of wood products are accounted for by the country in the year of harvesting (removal). The proposed method recommends that storage of carbon in forest products be included in a national inventory only in the case where a country can document that existing stocks of long term forest products are in fact increasing.

    7. IFM - Improved Forest Management - A suite of practices that reduce the social and environmental impacts of forestry activities while maintaining forest product supply These practices include:
      1. RIL - Reduced Impact Logging - An established set of timber harvesting practices designed to reduce the damage to the forest from timber extraction.
        Practices include:
        • Using innovative, low-impact logging equipment—such as the monocable winch system—that slide logs along the forest floor with long cables, reducing the damage to forests by bulldozers;
        • Improved design and construction of roads and skid trailc>s to minimize width and length required to access trees designated for harvest ;
        • Cutting trees so that they fall in a specific direction to minimize damage to other trees and maximize timber recovery (directional felling);
        • Cutting away vines that get tangled in the tree tops so that a cut tree does not bring several other non-commercial trees down with it;
        • Testing for hollow trees before they are cut down to avoid the wasteful destruction of trees that provide high ecosystem function but little or no timber value;
        • Proper identification of marketable species before cutting so that nonmarketable species are not cut down and abandoned; and
        • Construction of water bars (small ditches) across roads and skid trails to divert runoff and reduce erosion.

      2. Protection of conservation zones: IFM practices include the identification and special management of conservation zones, including:
        • Riparian buffer zones - areas where land meets streams or rivers, which are sensitive to erosion and have high plant and animal species diversity;
        • HCVF's - High Conservation Value Forests - Forests that contain concentrations of rare species, rare ecosystems, and/or areas of importance to local people;
        • Steep slopes sensitive to erosion; and
        • Corridors – forest areas that connect two or more larger blocks of forest.

      3. Silviculture: IFM also includes practices to ensure regeneration of native timber tree species, which helps maintain native tree diversity and provide a long-term source of income and employment. Some of these practices reduce emissions (e.g. extended rotation times, reduced damage to crop trees) while others can increase emissions (e.g. larger canopy openings to regenerate shade intoleran timber species); thus, careful planning is often necessary to achieve both emissions reductions and sustainable timber supply.

    8. LULUCF - Land Use, Land Use Change and Forestry - Defined by the UN Climate Change Secretariat as "A greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use, land-use change and forestry activities." LULUCF has impacts on the global carbon cycle and as such these activities can add or remove carbon dioxide (or, more generally, carbon) from the atmosphere, contributing to climate change. . Additionally, land use is of critical importance for biodiversity.

    9. MRV - Measurement, Reporting and Verification - Monitoring systems that allow for credible measurement, reporting and verification of REDD+ activities are among the most critical elements for the successful implementation of any REDD+ mechanism. Both remote sensing and ground based data is needed to monitor forest carbon emissions. UN-REDD is collaborating with the Group on Earth Observation (GEO), INPE and Google in order to improve access to data and expertise on remote sensing.

      For example, While Mexico has implemented a 15-day early warning system and produces a five-year national assessment of land use changes, it currently lacks an operative satellite system to monitor annual land use changes. Therefore, in the short-term MRV activities will include the development and implementation of an operative satellite monitoring system to offer annual national activity data

    10. NFI - National Forest Inventory - Provide a single authoritative source of forestry data at the national level. Ensure the development of sound forest policies. Ensure the viability of forest industries and the development of effective forest conservation strategies.

    11. PES - Payments for Environmental Services - National PES schemes are intended to compensate those providing environmental services (forest owners, for example). Costa Rica’s well-known scheme is intended to compensate farmers for not deforesting their lands. It is not a purely commercial mechanism: to meet its objectives it has relied upon additional subsidies (from a gas tax) and regulation, including a moratorium on deforestation. PES schemes are designed with conservation in mind, not poverty alleviation.

    12. REDD - Reducing Emissions from Deforestation and Forest Degradation - A set of steps designed to use market/financial incentives in order to reduce the emissions of greenhouse gases from deforestation and forest degradation. Its original objective is to reduce green house gases but it can deliver "co-benefits" such as biodiversity conservation and poverty alleviation. Deforestation is the permanent removal of forests and withdrawal of land from forest use. Forest degradation refers to negative changes in the forest area that limit its production capacity.

      REDD is presented as an "offset" scheme of the carbon markets and thus, will produce carbon credits. Recent work shows that the combined contribution of deforestation, forest degradation and peatland emissions accounts for about 15% of greenhouse gas emissions, down from earlier estimates of 25% and about the same as the transportation sector. It is increasingly accepted that mitigation of global warming will not be achieved without the inclusion of forests in an international regime. As a result, it is expected to play a crucial role in a future successor agreement to the Kyoto Protocol.

    13. REDD+ - Goes beyond deforestation and forest degradation, and covers all activities that reduce emissions from deforestation and forest degradation including:
      • the role of conservation
      • sustainable management of forests
      • enhancement of forest carbon stocks.

    14. Reforestation - This process increases the capacity of the land to sequester carbon by replanting forest biomass in areas where forests have been previously harvested.

    15. REL - Reference Emission Levels - The amount of gross emissions from a geographical area estimated within a reference time period (REDD) RL - Reference Level -The amount of net/gross emissions and removals from a geographical area estimated within a
      reference time period (Conservation, SMF, EFCS)

      Once set they cannot be changed during an implementation period. A fixed reference is fundamental for incentivizing action. They are based only on historical data of land uses, GHGs emissions/ removals, socio-economic variables no projections and no forward looking baseline in to minimize uncertainty past decade of economic growth may overestimate upcoming decade.

      There are three possible technical approaches that potentially support three different REDD implementation approaches
      1. Simplified: only gross emissions from forest land converted to other land uses. Gross carbon stock change (∆C) in areas deforested (ADEF) during the reference period. In this case the carbon stock concept could be further simplified and be related only to some carbon pools (e.g. above ground biomass) (Deforestation) -- Category 2
      2. Complete: gross GHGs emissions related to decreases in forest carbon stocks Gross carbon stock changes (∆C) in areas deforested (ADEF) during the reference period plus net decrease of carbon stocks (∆C) at national level in degraded forest land (ADEG) and non-CO2 gases emissions during the same period (Deforestation and degradation) – Category 3 / IPCC GPGS.

        If forest lost is matched by expanding plantations, this strategy could allow a country to benefit from increased revenue from both plantations and REDD credits.
      3. Sector: full GHGs balance from the whole Forest estate - Sum of all carbon stock changes (∆C) occurring in forest land (AFL) during the reference period, due to:
        - Conservation/SFM of Forest land (forest land remaining forest land)
        - Forest land conversion to other land uses (DEF)
        - Land Conversion to forest land (A/R) plus non-CO2 gases emissions during the same period (CH4, N2O)
        (Deforestation, forest degradation, SFM, conservation) -- Category 3


    16. RMU - Removal unit On the basis of land use, land-use change and forestry (LULUCF) activities such as reforestation. Equal to one tonne of CO2 can be traded and sold under the Kyoto Protocol’s emissions trading scheme.

    17. SMF - Sustainable Forest Management - SFM can cover a wide range of very different forest management strategies from conversion of native forest to plantation to maintenance of old growth native forest in order to maintain it in a pristine condition. SFM is a term commonly used by the forest industry to cover these two extremes and everything in between.

    18. Sustainable Land Management - With nearly two times as much carbon in soil than in the atmosphere, small changes in the level of carbon in soils can drive large changes in atmospheric carbon concentrations. Sustainable land management projects that increase the carbon content of soils represent a “triple win” for society: development, climate change resilience, and climate change mitigation.

      Healthy and fertile croplands increase the productivity of farms and the incomes of farming communities. In addition, cropland management techniques promote resilience to variations in climate, encouraging stability and food security. Finally, the sequestration of carbon in soils is a viable and quantifiable way to reduce atmospheric carbon. The sequestration of carbon in soils is currently a neglected part of the climate solution, yet it is important for mitigation, adaptation, and rural communities

    ecosystems in middle and high latitudes  Source: Intergovernmental Panel on Climate Change 2000 

    3. Business Case
    • A significant development was achieved at the Cancun Conference (COP 16). For the first time, the importance of stemming the loss of tropical forests for mitigating global climate change with financial support from the industrialized world was enshrined in an international agreement. The Kyoto Protocol’s Clean Development Mechanism has only allowed incentive payments to be made for afforestation and reforestation in developing countries, and only at the level of projects. With COP 16 decision, entire jurisdictions (including countries themselves) could receive incentives, subject to verification that emissions have been reduced against a reference level. All developing country activities referred to as “REDD+” are now eligible for financial support.
      They are as follows:
      • Reducing emissions from deforestation (actions to diverge from the reference level by reducing the conversion of forest to nonforest);
      • Reducing emissions from forest degradation (diverging from the reference level by reducing the gradual loss of biomass because of activities under the canopy);
      • Conservation (continued good stewardship of forests);
      • Sustainable management of forests (reducing emissions through harvesting activities with lower impact); and
      • Enhancement of forest carbon stocks (enhanced sequestration, for example, through reforestation)

    • The meteoric rise of REDD’s market share (+500% from 2009 to 2010) can be attributed to formal international recognition for REDD and conservation-based REDD+ as critical for climate change mitigation as well as likely pre-compliance interest in the project type under California’s emerging cap-and-trade program. At the same time, REDD gained market standing on the platform of the first REDD project methodologies approved for use by the Verified Carbon Standard (VCS) and through forest-focused third-party standards like Brasil Mata Viva (BMV).

    • The principles or objectives of the Cancun decision will still need to be operationalized. The Subsidiary Body on Scientific and Technological Advice (SBSTA) is expected to develop modalities on the setting of Reference Emission Levels and the design of measurement, reporting, and verification systems (MRV) and to propose guidance on the establishment of information systems by developing countries to report on safeguards. Even though the magnitude of finances required for
      REDD+ calls for the involvement of the private sector, the role of markets in mobilizing funding for REDD+ still needs to be discussed under the UNFCCC.

    • The rules governing the treatment of land use, land-use change and forestry for the second commitment period are currently being renegotiated as part of the Bali Action Plan under the Ad-Hoc Working Group on Further Commitments for Annex 1 Parties under the Kyoto Protocol (AWG-KP). The most recent options for rule changes under consideration are summarized in a "Non-Paper" the co-chairs of the contact group on LULUCF (as of June 12)


    4. Benefits
    • As stated in the background, in order to constrain the impacts of climate change within limits that society will reasonably be able to tolerate, the global average temperatures must be stabilized within two degrees Celsius. This will be practically impossible to achieve without reducing emissions from the forest sector, in addition to other mitigation actions.

    • Cost Effective Carbon Abatement - The creation of low-cost offsets through a scheme, such as REDD+, offers import countries considerable opportunities for cost-effective abatement. The cost containment opportunities justify the considerable work needed to develop offset schemes.


    5. Risks/Issues
    • Structural Issues - How the system will work? What will be the unintended consequences?
      • Baseline - Will it be based on current emissions levels or historical deforestation rates, a business-as-usual scenario? Will countries with different forest covers and historic deforestation rates hold different interests in the way the reference levels are constructed?

        A further critical element of the baselines debate concerns whether to measure standing carbon stocks instead. This approach is favored by countries that are still heavily forested and may have made considerable efforts to remain so. If they are excluded from REDD, the benefits would go only to the most prolific deforesters.

        Natural changes, such as forest fire and dieback, cannot be excluded (although it could be argued that these are no longer entirely natural, because of the impacts of climate change on weather patterns and forest health.

        Solutions that have been proposed to these difficulties include:
        • Countries being rewarded for reductions relative to historic emissions and on the basis of reductions below an agreed global baseline; and supported by a combination of marketand fund-based financing (Strassburg, 2008).
        • The use of a Target Band or Range Approach instead of a baseline, which allows countries to increase the financial benefits they accrue per credit the closer they get to their upper targets. However, this approach could make it difficult to generate full-value credits and to identify leakage.

      • Measuring Forest Degradation - There is no consensus on the definition for forest degradation. If degradation is not included in REDD, great quantities of carbon could be lost without the system recognizing it. In some countries, such as those in the Congo Basin, losses from degradation tend to be much higher than those from deforestation. However, the fact that degradation data may be less reliable – and is more expensive to acquire – is likely to discourage carbon finance investors, which may mean negotiators choose to exclude degradation in order to accommodate carbon trading.

        Even if methodologies are deemed sufficient, cost could still be a stumbling block, because:
        • Satellite imaging is expensive
        • ‘Ground truthing’, is costly, which is particularly important if degradation is to be included (still a contested point, for precisely this reason);
        • Installing monitoring and verification systems are up-front costs, whereas income through carbon financing is likely to be ex-post; and
        • Associated technical documents will be inaccessible to local communities without advice from external consultancies

      • Measuring Emissions of Methane (CH4) and Nitrous Oxide (N2O)
        These gases are influenced by land use, land-use change, and forestry activities (e.g., restoration of wetlands, biomass burning, and fertilization of forests). Hence, to assess the greenhouse gas implications of LULUCF activities, changes in CH4 and N2O emissions and removals — the magnitude of which is highly uncertain — would have to be considered explicitly. There are currently no reliable global estimates of these emissions and removals for LULUCF activities.

      • Ex-Post Payments and Liability Contracts - Carbon finance is also likely to disadvantage smaller players. Payments may be made ‘ex-post’, which means that the project is paid after the delivery of emissions reductions, because of the uncertainty associated with REDD. This would be difficult for smaller projects because they would have to fund upfront and operational costs from other sources. Alternatively, projects may have stringent risk assessments and contractual liability arrangements attached to them, meaning that the seller bears the risk of project failure. Both scenarios would be particularly onerous for smaller projects run by local communities.

      • Carbon Leakage - Negotiators are also concerned that REDD projects may halt deforestation at one site, but that illegal logging practices could be shifted elsewhere. Will the programme actually slow deforestation or will loggers just move to areas not covered by the scheme? A project-level approach could mean that deforestation activities simply shift to another area in the same country (depending on the specific causes of deforestation in that country). One approach to this predicament is to focus efforts at the national level and to involve as many countries as possible. Even so, a question still remains about possible leakage from tropical forests to boreal and temperate forests. Norway is working on a project with Guyana to avoid leakages that would lead to deforestation pressures moving to countries with currently low deforestation, like Guyana, when current high deforesters start to reduce their rates. Ultimately, the only real solution is to remove the underlying causes of deforestation.

        Commercial agriculture, including large-scale cattle ranching, is the predominant driver of deforestation in Latin America and Northern Dry Africa; and commercial crops, including for biofuels feedstocks, predominate in some South-East-Asian countries. On the other hand, commercial timber extraction is a more influential driver in South-East Asia as a whole. Commerical fuelwood extraction has also been identified as an emerging driver in ‘forest-poor’ countries with rapidly expanding urban centers , although it is important to bear in mind that much fuel wood collection is probably of fallen dead wood or offcuts from industrial felling.

      • Additionality - Accounting for reductions in deforestation that might have happened anyway (akin to the concerns about whether CDM projects are really additional). For example, Indonesia and Malaysia had very high rates of deforestation in the 1980s and 1990s, and deforestation is now likely to focus on highland areas. This means that deforestation rates can be expected to decrease anyway, for ‘mechanical’ reasons. Some countries are therefore proposing that baselines account for ‘anticipated trends in deforestation.’

      • Forward Selling - Trees reach maturity over a course of many decades. Project developers and offset retailers typically pay for the project and sell the promised reductions up-front.

      • Permanence - Forests, or at least trees, are impermanent by nature, and forest fires, disease, climatic changes, natural decay and timber harvesting could impede reductions in deforestation rates. Human causes clearing, burning, or mismanagement From an investor’s point of view this is a significant challenge to guaranteed profit-generation and the reason why ex-post payments are likely to be preferred.

        In other systems, this is resolved by the use of short-term and long-term temporary credits (tCERs and lCERs respectively), which have to be renewed at the end of a given period or if forest stocks disappear for any reason. Thus the liability for the project rests with the purchaser (although purchasers can also insure against credits expiring unexpectedly). However, temporary credits generate less income, so the sellers may prefer to shoulder liability themselves and sell more expensive permanent credits.

      • Transaction Costs - REDD carbon credits might be so complex and have such high transaction costs that only gthe largest companies operating to economies of scale are able to participate. because of the uncertainties associated with deforestation projects (because of storms or forest fires, for example) project managers are likely to find themselves saddled with the projects’ risks and liabilities. They may also find themselves responsible for finding upfront funding and operational costs to tide them over until they are paid at the end of the project period. Either way, larger and richer organisations operating to economies of scale can deal with these difficulties much more easily, than Indigenous Peoples and local communities, who may therefore find themselves in a poor negotiating position right from the start. They may also have to address language barriers and hire or find assistance to deal with the technical complexities involved in establishing, monitoring and verifying REDD projects.
      • Monopsony Structure - Largely due to the limited number of organisations capable of verifying carbon measurements to IPCC standards. Commodities markets are already unfavorable to producers and privilege intermediaries, largely because of the inherent nature of commodities themselves. Moreover, REDD’s global reach and scale suggest that intermediaries will obtain monopsony positions relative to projects.This results in the homogenisation of prices offered by the credit buyer to a project developer. More importantly, it also diverts the benefits of REDD+ away from communities and towards the middle men, in contrast to REDD+’s stated developmental objectives, whilst increasing the costs of REDD+.

      • Poor Transaction Structure - Transactions in REDD are structured as over-the-counter (OTC) arrangements, a fact that impedes REDD’s developmental goals and leads to a serious misallocation of resources. Forest carbon is a commodity. It is sourced – and may even be traded – “over the counter” (OTC), meaning outside of an exchange trading process. It is then aggregated and traded by intermediaries. The first transaction, where a project sells its carbon to an intermediary, is referred to as the “primary” market. Secondary markets are where the intermediary places that carbon with other parties – end users of credits, governments, speculators, private investors and the like. The primary-secondary structure is not a choice. It is inherent to REDD’s design because the people generating the asset are neither qualified nor inclined to trade their assets on a market.

        The problem is that there is no need for OTC flexibility in forest carbon. The end asset is largely the same regardless of its source, which makes bilateral, OTC-style contracts completely unnecessary. Why does this matter? Because OTC contract negotiations have their own peculiar dynamic, one that creates other types of risks, both for the individual parties and for the market as a whole:
        • Default. OTC contracts are bilateral, so that the counterparties are subject to market risk as well as default risk from their counterparty. This is more dangerous in REDD, where forest projects in OTC deals are completely dependent upon a single, controlling counterparty and may be completely ruined by a default. Also, because projects have very little interaction with each other, multilateral default protections do not exist.
        • Pricing Power - Active participants may have significantly better knowledge of market conditions and contract terms than occasional participants. This most especially disadvantages forest communities and REDD project managers, for whom an OTC carbon “trade” is a once-in-a-lifetime decision. The result will be that REDD projects will receive lower prices for their carbon, forcing them to cut operational costs.
        • Complexity  - Derivatives contracts are complex legal documents and firms with more experience are also more skillful in structuring them to their advantage. This is compounded by the difficulty of creating support systems for these businesses – due to the complexity of the requirements, the pricing and risk management systems that support these markets frequently do not completely match the actual contract terms. Again, this will represent a major disadvantage for REDD projects, who will be forced to either muddle through these issues or engage expensive outside help.
        • Oversight - This asymmetry of information applies to regulators in these markets as well. They cannot observe systemic risks building until those risks have already had a negative impact, and regulatory actions must be prescriptive rather than preventive.
      • Poorly Defined Assets - From a trading point of view, the process which forest creates carbon is ill defined to the point of being unacceptably risky. It contains a vague, poorly defined and scientifically unreliable process for creating forest carbon. 

      • Unsolvable Clearing Problems - As a consequence, pushing these commodities through the derivatives trading framework will prove impossible. This will either cause the trading system to not be created in the first place, or (as seems more likely) will result in the creation of a substandard, risky and ultimately destructive forest carbon market

    • Economic Risks -
      • Reduced Emission Reductions - To what extent can large emitting nations be allowed to use credits as a substitute for internal efforts to reduce emissions? Will REDD credits flood carbon markets and drive down prices making them a more attractive option than emission cuts?

        Leading conservation groups opposed the inclusion of forestry credits in the Kyoto Protocol due to fear that cheap carbon credits would flood the carbon market, thereby stalling other climate change mitigation programs. Allowing countries with carbon intensive lifestyles to continue consuming inequitably and unsustainably, by permitting them to fund cheaper forest carbon 'offsets' in developing countries, diverts critical resources and attention away from measures to address fossil fuel consumption and the real underlying causes of deforestation.

      • Price of Timber - REDD could significantly reduce the supply of timber which could lead to rapidly increasing timber prices and thus more incentive to deforest. Reducing demand for timber and agricultural commodities must be an immediate priority. Yet REDD as it is currently construed seems most unlikely to address this issue. Worse, it could even aggravate the situation by reducing timber supplies.

      • Illegal Logging is often listed as one of the prime proximate drivers of forest degradation, and one of the hardest to stop, especially in the absence of any reduction in demand for timber. Yet without such a reduction in demand, REDD could actually increase illegal/industrial logging (by leading to an increase in timber prices, as discussed above).

        It has been estimated that illegal activity was responsible for between 73% and 88% of Indonesia’s deforestation in 2006; and the Indonesian government has estimated that 2.8 million ha of forest, worth US$3.3 billion, is lost to illegal logging every year. In Amazonia, illegal activity could account for anything up to 60% of deforestation (at least down from 80% in 1997). Similarly, estimated levels for Cameroon are alleged to be about 50%; and for Papua New Guinea about 70% (Saunders & Nussbaum, 2008:2)

        It may not be reasonable to assume complex REDD policies involving large amounts of money work in countries unable to contain illegal logging and forest conversion in the first place. And if increased infrastructure, good governance and financing can help to stem these illegal activities, why not use new or existing policy measures to target these aspects directly?

      • Price of Land - If REDD leads to timber or land increasing significantly in price, as may already be happening, it is likely to have significant impacts on poor forest-dwelling communities and on land reformprogrammes.The simple fact of the forest becoming an increasingly valuable commodity will mean that it is more likely to be wrested away from local people.

    • Political Risks - Who benefits?
      • Distribution of Benefits - How can the benefits from REDD be distributed to forest communities in a just, equitable way that minimizes capture of the benefits by national governments or local elites? Local inhabitants, the communities that live in the forests, might be bypassed, not consulted and won't actually receive any revenues.

      • Loss of Sovereignty - Prioritising investment decisions that focus on maximizing profits and allowing foreign investors to buy up forest services reduces developing countries’ sovereignty over their natural resources. This is one of the reasons given by Brazil’s opposition for opposing the use of carbon markets to fund REDD and is the reason why it has proposed an alternative funding mechanism.

      • Indigenous Rights - To whom, if anyone, do forests belong is a key moral and ethical dilemma. And who has the rights to sell forest carbon credits? It is certainly clear that in the absence of secure land rights, Indigenous Peoples and other forest-dependent communities have no guarantees that they will receive any form of REDD incentive or reward for their extensive forest conservation efforts.




        Up to 1.6 billion people are at least partially reliant on access to forests for their everyday needs (FAO, 2008); and some 60 million Indigenous People depend wholly on forests for all their requirements

        REDD policies will trigger a rapid expansion in lands set aside for REDD projects. In many countries, governments and businesses are likely to ignore the customary and territorial rights of Indigenous Peoples, as they seek to protect an increasingly valuable resource, violently or otherwise. The simple fact that forests are becoming an increasingly valuable commodity means that they are more likely to be wrested away from local people.

        Commodifying forest carbon is also inherently inequitable, since it discriminates against people, and especially women, who previously had free access to the forest resources they needed to raise and care for their families, but cannot afford to buy forest products or alternatives. Any REDD projects that deny local communities and Indigenous Peoples access to forests risk having grave impacts on poverty and the achievement of the Millennium Development Goals.

      • Subsistence Farming - To what extent are subsistence farmers responsible for deforestation; and how much would it really cost to compensate them? An overly general approach to subsistence farming can also lead to the bundling together of many different kinds activities under the one heading, including:
        • Slash-and-burn activities, including by people who have migrated to the forests
        • Shifting cultivation
        • The collection of non-commercial fuelwood and non-timber forest products
        • Traditional, sustainable types of forest farming, that are known to gradually increase carbon sequestration.

      • Corruption - Facilitate corruption and poor governance in countries with tropical forests, because of the large sums of money proposed and the complex nature of the financial mechanisms likely to be involved. Given the current political institutions in many developing countries, it is likely that significant financial power will be given to a very small group of people or one individual.  Forestry departments are among the most corrupt departments in some of the most corrupt countries in the world.

        REDD could offer the opportunity to corrupt government officials to benefit from low rents in some areas and REDD income in others.

    • Environmental Risks -
      • Monocultures and Invasive Species - In an effort to cut costs, some tree-planting projects introduce fast-growing invasive species that end up damaging native forests and reducing biodiversity. For example, in Ecuador, the Dutch FACE Foundation has an offset project in the Andean Páramo involving 220 square kilometres of eucalyptus and pine planted. The NGO Acción Ecológica criticized the project for destroying a valuable Páramo ecosystem by introducing exotic tree species, causing the release of much soil carbon into the atmosphere, and harming local communities who had entered into contracts with the FACE Foundation to plant the trees. However, some certification standards, such as the Climate Community and Biodiversity Standard require multiple species plantings.

      • Plantations Included in REDD Definition - Plantations are not forests. Large-scale monoculture tree plantations cause serious environmental, social and economic problems. Furthermore, plantations store only 20% of the carbon that intact natural forests do. It thus seems inconceivable that the UN Framework Convention on Climate Change (UNFCCC) would sanction any process that allows natural forests to be replaced with plantations. Yet this is exactly what is being proposed in REDD. Some countries even support a ‘net deforestation’ approach: this would allow them to continue logging and cutting forest to make way for agricultural commodities, including biofuels, in some areas, while conserving forests and/or extending plantations in others.

      • Biodiversity - What might happen in low carbon, high biodiversity regions. UNEP, for example, refers to research indicating that only 15% of global carbon stocks are currently located in protected areas (Price, 2008). Will high biodiversity areas be neglected or de-prioritized? Ormight they be funded, as suggested by UNEP staffer Jeff Price, through premiums attached to high biodiversity REDD credits, or even through a completely separate 0financial mechanism?-*

      • Albedo effect - A study suggested that "high latitude forests probably have a net warming effect on the Earth's climate", because their absorption of sunlight creates a warming effect that balances out their absorption of carbon dioxide. This view is however being challenged by other studies showing that despite the negative albedo effects of temperate forests there is a net benefit and in addition there is weak evidence of a positive albedo effect in the tropics from clouds generated by forests.

    • Ethical Considerations
      • Will Good be the Enemy of the Necessary - It is argued that the cumulative atmospheric concentration of CO2 can be reduced by deferring deforestation: even if deforestation rates return to their original level after a certain period, cumulative concentrations of greenhouse gases will still be less than they would have been (Ebeling, 2007). There now seems to be increasing governmental consensus around what is known as the ‘50-50-50’ option which involves: “reducing deforestation rates 50% by 2050 and then maintaining them at this level until 2100 which would avoid the direct release of up to 50GtC [gigatonnes of carbon] this century, equivalent to nearly 6 years of recent annual fossil fuel emissions.

        The second questionable supposition is that any agreement is better than no agreement. This may be true for some international discussions on less critical issues, but is it for discussing a climate crisis where urgent and radical action is the only way to avert runaway climate change?

      • Equity - Because REDD is primarily intended to create financial incentives that will prompt those engaged in deforestation to switch to managing standing forests., it would reward those engaged in logging and industrial agriculture, while ignoring those countries and communities that have low deforestation rates.

    • Ignored Alternatives
      • REDD - Ignores Root Causes of Deforestation - Nailing down demand-side drivers in importing countries and resolving governance, poverty and land tenure issues in forested countries.

      • Market Bias - The use of methodologies that include exporters’ profits as opportunity costs also implies that those companies might be compensated for lost profits; and that only the market can change concession-holders or other land-holders’ behavior. However, as can be seen in Indonesia, it is quite possible for politicians to simply revoke concessions for logging and commodity production if they have sufficient incentive to do so.

        Considering the ‘full’ costs, including company profits, generates extremely high figures which are then used to justify the use of carbon trading, on the basis that no other funding source can generate finance on the scale required.


    6. Success Criteria
    1. Structure - Many of the emission reduction opportunities are beyond CDM, notably in the REDD+ space. They do not have clear methodologies and are in sectors that may not be amenable to conventional financing. Organizing, financing, and implementing carbon projects in such sectors as low-tillage agriculture and sustainable land management will require developing new organizational and financing models.

    2. Indigeneous Rights - The knowledge and rights of indigenous peoples and local communities must be respected. Indigenous peoples and local communities must be able to participate fully and effectively.

    3. the national forest governance structures must be transparent and effective, taking
      into account national legislation and sovereignty.

    4. REDD+ must not encourage the conversion of natural forests to plantations.

    5. REDD can only help to avoid climate change “if it is based on sustainable forest management and integrated into broader carbon emission reduction strategies…. Weak forest governance and the marginalization of forest dependent communities are important factors that exacerbate forest loss and degradation. As long as these challenges remain unresolved, the success of REDD is uncertain and REDD mechanisms might even inadvertently reinforce corruption, undermine human rights and threaten forest biodiversity” (IUCN, 2008)


    7. Case Studies
    1. GRIF - Guyana REDD Investment Fund - Norway will be the first contributor to the GRIF, and will pay US$30 million into the fund when it is established, planned at the end of this month. The payment is in recognition of Guyana’s efforts to protect its 16 million hectare rainforest, and follows the memorandum of understanding signed by the two countries in November last year. Norway intends to pay up to US$250 million into the GRIF between 2010 and 2015, based on Guyana’s performance in avoiding greenhouse gas emissions from deforestation and forest degradation, as well as Guyana’s on-going and planned strengthening of inclusive and transparent forest management. Guyana will invest GRIF revenues to implement the country’s Low Carbon Development Strategy (LCDS). This will enable Guyana to place its forest under long-term protection, catalyze public and private investment for clean energy (to move virtually the entire economy away from fossil fuel energy dependence), and create new low carbon economic and employment opportunities for forest dependent communities and other Guyanese citizens. The process will be evolving with the full and effective participation of involved stakeholders, including indigenous peoples groups.

      In June 2011, The Norwegian Government responded to the eight points of contention documented by a body of civil society personalities on March 24, 2011, as to the state of affairs of the Guyana REDD Investment Fund, saying that the partnership is very much a work in progress, one that will improve over time. With respect to the complaint over the delays in the preparation of projects, the letter said that getting the modalities of the GRIF sufficiently established and getting the projects approved by the GRIF Steering Committee has taken longer than expected. “This is a reflection of getting a new system to work, including with respect to the application of fiduciary, environmental and social safeguards,” the letter said.

      It noted that it is taking the matter seriously and said the Government of Guyana has prepared six projects and the respective partner entities are at present reviewing these. It said that as of now, no funds have been disbursed from the GRIF, even though Norway has already released the funds to Guyana, amounting to US$70M.

      Another issue that the stakeholders raised in their letter is that of the rate of deforestation under the agreement. The Norwegian letter explained that the intention of the agreement is to maintain a low level of deforestation. “By any means of comparison, the deforestation rate in Guyana remains extremely low. At deforestation rates as low as those observed in Guyana, even very small deforestation events will cause significant [percentage-wise] changes in the deforestation rate,” the letter stated.

      It said Guyana and Norway are intent on quickly disincentivizing any systematic upward trend in Guyana’s deforestation rates. “Based on the revised numbers, we have therefore put in place an incentive structure for that purpose. The incentive structure is publically available in our Joint Concept Note and implies payments start to fall at 0.56 percent deforestation and cease completely at 0.1 percent. By any measure, this is ambitious,” the letter said.

      It said that to further strengthen transparency and credibility of forest management practices and authorities in Guyana, Norway has agreed to establish Independent Forest Monitoring in the country. “An open, competitive tender process to procure the services of a credible party to fill this role has just been completed. When the IFM becomes operational in the near future, this will also be an important recipient of any information you may possess regarding suspected irregularities in the Guyanese forestry sector,” the letter stated.

      Regarding the need for strong and consistent safeguards, the letter said that these safeguards will be applied with those of the IDB, the World Bank and the UNDP, dependent on which institution will be partner entity for the relevant project. It noted that these institutions have played an important role as channels for the Norwegian multilateral cooperation for many years. They have environmental, social and fiduciary safeguards that are compatible with the requirements for the use of Norwegian funds,” the letter said.

      With regard to the complaint about the weak participatory process, the Norwegian letter advised that the stakeholders make their concern known to the authorities in Guyana.

    2. Norway Indonesia REDD+ Partnership - Indonesia’s deforestation rates are significant, and recent estimates indicate that between 2000 and 2005, 3.5 million hectares of forests have been lost (an area larger than Belgium), or around 2.9% of Indonesia’s total forest area.

      In October 2009, President Susilo Bambang Yudhoyono committed to reducing Indonesia’s CO2 emissions by 26% against a business-as-usual trajectory in 2020, the largest absolute reduction commitment made by any developing country. Indonesia has set a bold target and Norway wanted to support the Indonesian government’s efforts to realize its commitment.

      In May 2010 Norway and Indonesia signed a letter of intent to support Indonesia’s efforts to reduce greenhouse gas emissions from deforestation and degradation of forests and peat lands. Norway will support these efforts with up to 1 billion US dollars based on Indonesia’s performance, over the course of the next 7- 8 years.

      The partnership has three phases.
      1. In the first phase, funds will be devoted to finalizing Indonesia’s climate and forest strategy and putting in place enabling policies and institutional reforms.
      2. In phase two, the objective is to make Indonesia ready for the contributions-for-verified emissions reductions while at the same time initiate larger scale mitigation actions through a province-wide pilot project. Phase 2 includes
      3. i. A two year suspension on all new concessions for conversion of peat and natural forest.
        ii. Establishing a degraded lands database, starting in one or more appropriate provinces, to facilitate the establishment of economic activity on such lands rather than converted peatland or natural forests.
        iii. Enforcing existing laws against illegal logging and trade in timber and related forest crimes and set up a special unit to tackle the problem.
        iv. Taking appropriate measures to address land tenure conflicts and compensation claims.
      4. In the third phase, starting in 2014, the contributions-for-verified emissions reductions mechanism will be implemented nationally.

      In 2010 the money was spent on completing a national REDD+ strategy for Indonesia. However, the money will be distributed over a 7-8 year period and most of the funds are tied to verified emissions reductions by Indonesia.

      One focus-area of the partnership is sustainable management of forest and reduced emissions from the forest. Papua and Kalimantan are two areas of Indonesia with large tropical rainforests intact. They are also areas where insecure land tenure currently gives indigenous people and local communities little incentive to contribute to more sustainable management of forest.

      Indonesia agreed to declare a two-year suspension on new concessions on conversion of natural forests and peat forests into plantations.  The suspension was signed Indonesia's President in May 2011. This is not a “ban”, it is a temporary suspension, which applies only to “new concessions”. The Letter of Intent has nothing to say, and will not affect, concessions for clearance that have already been awarded, but not yet cleared.

      According to Greenomics-Indonesia, a Jakarta-based NGO, community and village forestry licenses are not among the many exemptions spelled under the presidential instruction that defines the moratorium. The instruction, issued last month, grants exemptions for industrial developers and allows business-as-usual in secondary forest areas by the pulp and paper, mining and palm oil industries.   "The only exceptions in the Presidential Instruction are for big business. In reality, the granting of licenses for community and village forestry development should have been prioritized for exclusion from the moratorium, especially as such activities are not environmentally destructive," said Greenomics Executive Director Effendi Effendi.

    3. Kenya Agricultural Carbon Project - The first project in Africa that sells carbon offsets from a sustainable land management project, improving the livelihoods of rural communities while tackling climate change. It brought the potential for carbon sequestration in soils to the forefront of carbon finance. Implemented by the Swedish NGO Vi Agroforestry, the project is located on over 40,000 hectares in the Nyanza Province and Western Province of Kenya. Smallholders and small-scale business entrepreneurs are trained in diverse cropland management techniques, including cover crops, crop rotation, compost management, and agroforestry. The farming practices both increase the yield of the land and sequester carbon in the soil.

      The project is developing the Sustainable Agriculture Land Management Methodology under the VCS. The first validation was finalized in November 2010 by Scientific Certification Systems. The project is currently undergoing the second validation. The BioCarbon Fund is leading the methodological work, together with Vi Agroforestry. It will purchase 150,000 emission reductions up to 2016.

    4. Green Wall of China - a series of human-planted forest strips in the People's Republic of China, designed to hold back the expansion of the Gobi Desert. It is planned to be completed around 2074, at which point it is planned to be 2,800 miles long.

      China has seen 3,600 km2 of grassland overtaken every year by the Gobi Desert. Each year dust storms blow off as much as 2,000 km2 of topsoil, and the storms are increasing in severity each year. These storms also have serious agricultural effects for other nearby countries, such as Japan, North Korea, and South Korea. The Green Wall project was begun in 1978 with the proposed end result of raising northern China’s forest cover from 5 to 15 percent and thereby reducing desertification.

      The 4th and most recent phase of the project, started in 2003, has two parts: the use of aerial seeding to cover wide swaths of land where the soil is less arid, and the offering of cash incentives to farmers to plant trees and shrubs in areas that are more arid. A $1.2 billion oversight system, including mapping and surveillance databases, is also to be implemented. The “wall” will have a belt with sand-tolerant vegetation arranged in checkerboard patterns in order to stabilize the sand dunes. A gravel platform will be next to the vegetation to hold down sand and encourage a soil crust to form. The trees should also serve as a wind break from dust-storms.

      As of 2009 China’s planted forest covered more than 500,000 square kilometers (increasing tree cover from 12% to 18%) – the largest artificial forest in the world. However, of the 53,000 hectares planted, a quarter has died and of the remaining many are dwarf trees, which lack the capacity to protect the soil. In 2008 winter storms destroyed 10% of the new forest stock, causing the World Bank to advise China to focus more on quality rather than quantity in its stock species.

      There is still debate on the effectiveness of the project. If the trees succeed in taking root they could soak up large amounts of groundwater, which would be extremely problematic for arid regions like northern China. For example, in Minqin, an area in north-western China, studies showed that groundwater levels dropped by 12-19 meters since the advent of the project.
      Land erosion and overfarming have halted planting in many areas of the project. China's booming pollution rate has also weakened the soil, causing it to be unusable in many areas.
      Furthermore, planting blocks of fast-growing trees reduces the biodiversity of forested areas, creating areas that are not suitable to plants and animals normally found in forests. "China plants more trees than the rest of the world combined," says John McKinnon, the head of the EU-China Biodiversity Program. "But the trouble is they tend to be monoculture plantations. They are not places where birds want to live." The lack of diversity also makes the trees more susceptible to disease, as in 2000 where one billion poplar trees were lost to disease, setting back 20 years of planting efforts.

      China’s forest scientists argue that monoculture tree plantations are more effective at absorbing the greenhouse gas carbon dioxide than slow-growth forests. So while diversity may be lower, the trees purportedly help to offset China’s carbon emissions.

      There are many who do not believe the Green Wall is an appropriate solution to China’s desertification problems. Gao Yuchuan, the Forest Bureau head of Jingbian County, Shanxi, stated that “planting for 10 years is not as good as enclosure for one year,” referring to the alternative non-invasive restoration technique that encloses a degraded area for two years to allow the land to restore itself. Jiang Gaoming, an ecologist from the Chinese Academy of Sciences and proponent of enclosure, says that “planting trees in arid and semi-arid land violates [ecological] principles”. The worry is that the fragile land cannot support such massive, forced growth. Others worry that China is not doing enough on the social level. In order to succeed many believe the government should encourage farmers financially to reduce livestock numbers or relocate away from arid areas.


    8. Companies/Organizations
    1. AWG-KP - The Ad Hoc Working Group on Further Commitments for Annex 1 Parties under the Kyoto Protocol - Currently discussing changes in accounting rules for LULUCF for the second commitment period of the Kyoto Protocol. Proposed changes relate to setting of national reference levels for carbon accounting for forest management interventions; the cap, or amount of offsets that would be permitted from forest management; and accounting for carbon stored in harvested wood products (HWPs).

    2. AWG-LCA - Ad Hoc Working Group on Long-term Cooperative Action - Mandated to explore options for the type of support that should be provided for Phase lll (development of result-based activities that are fully measured, reported, and verified). and will report to the Durban Conference (COP 17). It is likely that multiple channels will be proposed, recognizing the role of the private sector, including through carbon markets, in addition to government assistance.

    3. BioCarbon Fund - A fund managed by the World Bank aimed at projects that sequester or conserve carbon with forests and agriculture. This Fund “can consider purchasing carbon from a variety of land use and forestry projects; the portfolio includes Afforestation and Reforestation, Reducing Emissions from Deforestation and Degradation and is exploring innovative approaches to agricultural carbon.”

      The BioCarbon Fund will purchase 150,000 pollution credits by 2016 from a carbon sequestration project in Kenya. The Kenya Agricultural Carbon Project, which covers over 40,000 hectares, is the first project in Africa that sells carbon offsets from a land management project. It is being implemented by the Swedish NGO Vi Agroforestry, and it is being used as the basis for the development of a Sustainable Agriculture Land Methodology under the Verified Carbon Standard (VCS).

    4. CCBA - The Climate, Community & Biodiversity Alliance - An initiative led by Conservation International, CARE, The Nature Conservancy, Rainforest Alliance, and the Wildlife Conservation Society to promote the development of land management activities that simultaneously deliver significant benefits for climate, local communities, and biodiversity. The CCBA has two major initiatives:
      1. CCB - The Climate, Community and Biodiversity Standards - In use by more than 100 projects around the world. CCB Standards enable investors, policymakers, project managers and civil society observers to evaluate land-based climate change mitigation projects by identifying high-quality projects that adopt best practices to generate significant benefits for local communities and biodiversity while delivering credible and robust carbon offsets. CCB Standards do not quantify carbon reductions, so they are often “stacked” with a carbon standard – primarily VCS – to certify projects’ additional social and environmental contribution.

        In June 2011, CCBA announced that the first two carbon forestry projects have reached verification status against the CCB Standards. While run by different organizations, both projects are located in Kenya. The International Small Group and Tree Planting Program (TIST) managed by Clean Air Action Corporation is a community based reforestation project working with over 50,000 farmers located near Mount Kenya. The sub-project that has achieved verification is 1,565 hectares (3,867 acres) in size and has sequestered approximately 80,627 tons of carbon since inception in 2004 while also generating new sources of revenue and sustainable livelihoods for over 8000 community members. The second project, is run by Wildlife Works and is located in Kasigau is 169,741 hectares (419,439 acres) in size and has generated approximately 1,002,870 tons of greenhouse gas emissions reductions in the first year of operation, providing new and diversified alternative livelihoods to local people and conserving a critical corridor for endangered wildlife.

        Each carbon project that aims to meet the CCB Standards is first ‘validated’ by a third party auditor. The validation process includes a 30-day public comment period and a site visit to check that the project has been designed to meet the requirements of the CCB Standards criteria and is likely to generate the expected climate, community and biodiversity benefits. Once a project has made progress, third party auditors review another set of public comments and visit the site once again to ‘verify’ that the project has been implemented following the validated project design – and to determine what benefits the project has actually generated.

      2. The REDD+ Social and Environmental Standards - Being developed in collaboration with the governments of Ecuador, Nepal and Tanzania to enable government programs to demonstrate that their programs for reducing emissions from land are designed and implemented in a way that ensures a high level of social and environmental performance.

    5. CFS - The CarbonFix Standard - An initiative supported by over 60 organizations promotes
      the development of climate forestation projects to sequester carbon from the atmosphere. The CarbonFix Standard is administered by CarbonFix a non-profit association based in Germany.

    6. FIP - The Forest Investment Program - A program hosted by the World Bank within the Strategic Climate Fund (a multi-donor Trust Fund within the Climate Investment Funds). The FIP's overall objective is to mobilize significantly increased funds to reduce deforestation and forest degradation and to promote sustainable forest management, leading to emission reductions and the protection of carbon terrestrial sinks.

      To obtain REDD funding under World Bank rules, a country must develop strategies to reduce deforestation, a system for monitoring, reporting and verifying emissions reductions, and a reference scenario that accounts for historic and projected future deforestation rates. The bank’s own technical advisory panel expressed concerns about “significant weaknesses” in the plans of Guyana and Panama and suggested that “analysis of the drivers of deforestation was incomplete and poorly aligned with their proposed strategies”.

      As part of the Bank’s Strategic Climate Fund, which is one of two funds in the framework of the Climate Investment Funds. The FIP, established in 2009, will mobilize larger-scale funds to prepare national strategies for the implementation of REDD+ projects under the FCPC in selected pilot countries. Furthermore, it seeks to give funds to other schemes that promote carbon markets in forests, such as the UN-REDD programme. It achieves this by providing “scaled-up financing to developing countries for readiness reforms and public and private investments, identified through national REDD+ readiness or equivalent strategies.”

      The FIP funds are channeled through five multilateral development banks: The African Development Bank, Asian Development Bank, European Bank for Reconstruction and Development, Inter-American Development Bank, and the World Bank Group

      There is disagreement is over whether there is scope for the World Bank to be involved through its existing carbon funds, its newly proposed climate investment funds and its influence over the Global Environment Facility (GEF), which is currently the operating entity of the UNFCCC’s financial mechanism; or whether funds should be handled within the framework of the UNFCCC itself (a view held by many developing countries, as expressed by the G77/China).

    7. FCPF - Forest Carbon Partnership Facility - A global partnership focused on reducing emissions from deforestation and forest degradation, forest carbon stock conservation, sustainable management of forests and enhancement of forest carbon stocks (REDD+). The FCPF assists tropical and subtropical forest countries develop the systems and policies for REDD+ and provides them with performance-based payments for emission reductions. The FCPF complements the UNFCCC negotiations on REDD+ by demonstrating how REDD+ can be applied at the country level.

      Since it became operational in June 2008, the FCPF has created a framework and processes for REDD+ readiness, which helps countries get ready for future systems of financial incentives for REDD+. Using this framework, each participating country develops an understanding of what it means to become ready for REDD+, in particular by developing reference scenarios, adopting a REDD+ strategy, designing monitoring systems and setting up REDD+ national management arrangements, in ways that are inclusive of the key national stakeholders.

      FCPF consists of two funds: the Readiness Fund and the Carbon Fund. The former supports countries in developing a national REDD+ strategy (phase 1 and 2), while the Carbon Fund is a public-private partnership due to become operational in 2011 which facilitates the trading in forest carbon credits (phase 3). In the first phase, countries have to produce Readiness Plan Idea Notes (R-PINs), which are the bases for producing the Readiness Preparation Proposals (R-PP), in order to provide the framework for REDD+ in each country.


    8. FSC - Forest Stewardship Council - An international non-profit, multi-stakeholder organization established in 1993 to promote responsible management of the world’s forests. Its main tools for achieving this are standard setting, independent certification and labeling of forest products. This offers customers around the world the ability to choose products from socially and environmentally responsible forestry.

      The FSC Label means that rather than the state, consumers are used to create shifts in industry and regulate the negative environmental impacts of deforestation.

      The main competing forest certification system is the PEFC (Programme for the Endorsement of Forest Certification schemes), established by a number of stakeholders, including associations of the forest industry, pulp-and-paper production and forest owners[citation needed] in response to the creation and increasing popularity of FSC.

      FSC has faced criticism for a number of practices, including certifying plantations, clear-cutting, and logging of old-growth forests as sustainable forestry. It has also certified companies linked to social conflict and human-rights violations. In fact Asia Pulp and Paper (APP), a brand that has been widely criticized for large-scale rainforest and peatland destruction in Indonesia, was certified by the FSC until an article in the Wall Street Journal in 2007 pushed the FSC to drop it.

    9. Rainforest Coalition - A coalition of nations led by Papua New Guinea and Costa Rica calling for the inclusion of REDD in a global cap-and-trade system. Under such an approach, industrialized countries would finance REDD projects, mainly in developing countries, to compensate for their own emissions.

      The objective is ambitious – forested tropical countries collaborating to reconcile forest stewardship with economic development.

      Who: Developing Nations with rainforests -- partnering with Industrialized Nations that support fair trade and improved market access for developing countries.

      What: Facilitate new and improved revenue streams in order to underpin community-driven environmentally sustainable economic growth.

      How: Reform international regulatory, trade and economic frameworks to effectively align market incentives with sustainable outcomes.

      Participants: Countries participating within the various activities of the Rainforest Coalition include: Argentina, Bangladesh, Belize, Cameroon, Central African Republic, Chile, Congo, Costa Rica, Cote d'Ivoire, DR Congo, Dominica, Dominican Republic, Ecuador, Equatorial Guinea, El Salvador, Fiji, Gabon, Ghana, Guatemala, Guyana, Honduras, Indonesia, Jamaica, Kenya, Lesotho, Liberia, Madagascar, Malaysia, Nicaragua, Nigeria, Pakistan, Panama, Papua New Guinea, Paraguay, Samoa, Sierra Leone, Solomon Islands, Suriname, Thailand, Uruguay, Uganda,Vanuatu and Viet Nam

      Opponents - This is likely due to two major reasons: long-standing national sovereignty issues about the Amazon, and concern about price depression in the Clean Development Mechanism (CDM). So despite encouraging developments from the world’s largest rainforest nation, deep-seated sovereignty questions remain as to whether Brazil will help REDD along or continue standing in its way.

    10. SBSTA - Subsidiary Body on Scientific and Technological Advice - Provide the COP with advice on scientific, technological and methodological matters. Two key areas of work in this regard are promoting the development and transfer of environmentally-friendly technologies, and conducting technical work to improve the guidelines for preparing national communications and emission inventories. The SBSTA also carries out methodological work in specific areas, such as the LULUCF sector, HFCs and PFCs, and adaptation and vulnerability.

      The principles or objectives of the Cancun decision to include forests in any future agreement with the possibility of generating international carbon credits will still need to be operationalized. The SBSTA is expected to develop modalities on the setting of Reference Emission Levels and the design of measurement, reporting, and verification systems (MRV) and to propose guidance on the establishment of information systems by developing countries to report on safeguards.

    11. UN-REDD Programme The United Nations Collaborative initiative on Reducing Emissions from Deforestation and forest Degradation in developing countries. The Programme was launched in September 2008 to assist developing countries prepare and implement national REDD+ strategies, and builds on the convening power and expertise of the Food and Agriculture Organization of the United Nations (FAO), the United Nations Development Programme (UNDP) and the United Nations Environment Programme (UNEP).

      Norway continues to be the UN-REDD Programme’s first and largest donor. Since the Programme was launched in September 2008, Norway has committed US$52.2 million for 2008-2009, and another US$31 million for 2010. Denmark became the second donor country to join the UN-REDD Programme, committing US$2 million in June 2009 and another US$6 million in November 2010. At the end of 2009, Spain announced its pledge of US$20.2 million to the UN-REDD Programme over a period of three years, and confirmed US$1.4 million for 2010 in November 2010.

    12. VSC - Verified Carbon Standard (formerly called Voluntary Carbon Standard) - Founded in 2005 by “business and environmental leaders who identified a need for greater quality assurance in voluntary markets”. As their mission sates, they have some “freedom” to create their own rules of the game, by claiming, “to pioneer innovative rules and tools that open new avenues for carbon crediting and allow businesses, non-profits and government entities to engage in on-the-ground climate action”

      VCS created a “REDD+ Methodology Framework” to assist in the creation of REDD+ methodologies for project activities in the voluntary market. Each approved methodology has been developed by different consultancy companies such as InfiniteEARTH, Winrock International, Wildlife Works Carbon and Face the Future, to name a few.

      The Rimba Raya conservation project, which covers nearly 100,000 hectares of peat swamp forest in the province of Central Kalimantan, Indonesia was the first REDD+ methodology approved under the VCS. It was developed by InfiniteEARTH, written by Winrock International and funded by Shell, Gazprom Market and Trading and the Clinton Foundation.

      VCS has also developed methodologies for crediting AFOLU activities (Agriculture, Forestry and Other Land Use or REDD++), expanding the possibilities to agricultural, peat and pastoral lands. By involving more and more groups interested in profiting from REDD+, the VCS presents itself as an easy way forward without the “hassle” of official regulatory frameworks, while the official REDD+ text within the UNFCCC is still being hotly debated.

    5. REDD myths. A critical review of proposed mechanisms to reduce emissions from deforestation and degradation in developing countries. Friends of the Earth International, December 2008

      This paper analyses critically the measures of REDD negotiated by the United Nations. This analysis tries to answer various questions on REDD’s climate change mitigation power, as well as on who really benefits from REDD funds. The analysis focuses on the financial mechanisms and on their management, which influences its use at a national and local level. The paper suggests in conclusion that the measures should be implemented through participation of Indigenous People helping them to build sustainable livelihoods.

    6. REDD-Monitor - The website emerged from discussions between NGO networks in Europe and the South, who felt the need to share information about the way REDD is developing. REDD-Monitor critically analyzes the problems related to REDD and “avoided deforestation”. In doing so, they hope to help facilitate a public discussion about REDD and hope that by doing so they will make a useful contribution in answering the question “will REDD work?”
