REDD Methodology Modules

The American Carbon Registry (ACR), a non-profit enterprise of Winrock International, has approved the Reducing Emissions from Deforestation and Degradation (REDD) Methodology Modules for registration of projects on ACR.

Winrock International's development of the original REDD Methodology Modules, on which the ACR-approved modules are based, was made possible through the support of Avoided Deforestation Partners. Climate Focus, Carbon Decisions International, Silvestrum, and TerraCarbon LLC contributed to drafting the earlier version of the modules.

The Modules were approved through ACR's process of internal review, an open public comment period, and a scientific peer review by experts in the field of greenhouse gas methodologies for REDD. The peer review was conducted blindly, by independent experts outside of Winrock.

ACR wishes to express our gratitude to the methodology authors, Dr. Tim Pearson, Dr. Sandra Brown, and Dr. Sarah Walker of Winrock International, and to the scientific peer reviewers, for their efforts throughout the methodology drafting, review and approval process.

Background

The REDD Modules are applicable to projects reducing emissions from planned deforestation, unplanned deforestation, and degradation through non-renewable fuelwood collection and charcoal production. The modular approach is an effort to streamline methodology development and use. Rather than developing unique methodologies on a project-by-project basis, each aspect of the project from baseline setting to measurement, monitoring and leakage is treated in a discrete and independent module. Individual modules that are applicable to a specific project's circumstances can then be selected to create an overall methodology for the project.

The REDD Modules may be used on their own for project-level REDD activities, or alternately combined with ACR's forthcoming Nested REDD+ Requirements to register project-level activities nested within a jurisdictional accounting framework. In the latter case the REDD Modules would be used to account for methodological components not addressed by the jurisdictional accounting framework.

Structure

A framework module, REDD-MF, establishes the overall functionality of the methodology, indicates which modules are mandatory and optional, and contains the final calculation of Emission Reduction Tonnes (ERTs). REDD-MF constitutes, together with the modules and tools it calls upon, a complete REDD methodology applicable to projects reducing emissions from planned deforestation, unplanned deforestation, and degradation through removal of fuelwood.

Included underneath REDD-MF are:

1)    Three baseline modules:

  • BL-PL "Estimation of baseline carbon stock changes and GHGemissions from planned deforestation"
  • BL-UP "Estimation of baseline carbon stock changes and GHGemissions from unplanned deforestation"
  • BL-DFW "Estimation of baseline emission from forest degradation caused by extraction of wood for fuel"

2)    Four leakage modules:

  • LK-ASP "Estimation of emissions from activity shifting for avoided planned deforestation"
  • LK-ASU "Estimation of emissions from activity shifting for avoided unplanned deforestation"
  • LK-ME "Estimation of emissions from market effects"
  • LK-DFW "Estimation of emissions from displacement of fuelwood extraction"

3) M-MON "Methods for monitoring of greenhouse gas emissions and removals"

4)    Two miscellaneous modules:

  • X -STR "Methods for stratification of the project area"
  • X-UNC "Estimation of uncertainty for REDD project activities"

5)    Four tools:

  • T-SIG "Tool for testing significance of GHG emissions in A/R CDM project activities" - latest CDM-EB approved version
  • T-ADD "ACR Tool for Determining the Baseline and Assessing Additionality in REDD Project Activities"
  • T-BAR "Tool for AFOLU non-permanence risk analysis and buffer determination" - latest ACR-approved version
  • CPES"ACR Tool for the Estimation of Stocks in Carbon Pools and Emissions from Emission Sources," which includes estimation of carbon pools (above- and belowground biomass in live tree and non-tree pools, dead wood, litter, soil organic carbon, and long-term wood products) and of emission sources (biomass burning, fossil fuel combustion, and N2O emissions from nitrogen application). CPES was approved through a separate  public comment and peer review process, as part of ACR's Methodology for REDD - Avoiding Planned Deforestation, in 2011.
