Tool for Reversal Risk Analysis and Buffer Pool Contribution Determination
The Tool for Reversal Risk Analysis and Buffer Pool Contribution Determination (the Risk Tool) provides an assessment framework for Agriculture, Forestry, and Other Land Use (AFOLU) carbon projects to perform a Reversal Risk Analysis. A project’s Reversal Risk Analysis determines its Buffer Pool Contribution Percentage, which is the proportion of credits deposited at each issuance into the ACR Buffer Pool to mitigate the risk of unintentional reversals.
Version 2.0 of the Risk Tool introduces new methods and requirements for calculating project-specific and spatially explicit risks to the permanence of emission reductions and/or removals that are the result of natural disturbances and would be considered an “Unintentional Reversal”. The updated Risk Tool leverages published, publicly available, and geographically specific mapping datasets to determine natural disturbance risks and associated Buffer Pool Contribution Percentages.
The ACR Buffer Pool only compensates for Unintentional Reversals and thus, only unintentional types of risks are assessed in the Risk Tool.
The Risk Tool and the ACR Buffer Pool Terms and Conditions operate in conjunction with the legally binding Agriculture, Forestry, and Other Land Use (AFOLU) GHG Project Reversal Risk Mitigation Agreement between ACR and Project Proponents, which details the requirements for reporting and compensating for Unintentional and Intentional Reversals.
Project Proponents shall use the version of the Risk Tool that is available at the end of the Reporting Period being verified.
- Reporting Periods ending before November 19, 2024, shall use version 1.0 at their next full verification.
- Reporting Periods ending on or after November 19, 2024, shall use version 2.0 at their next full verification.
