Tool for Calculating the Long-Term Average of Forest Carbon Stocks , v1.0

The Tool for Calculating the Long-Term Average of Forest Carbon Stocks will provide a standardize procedure for determining when and how ARR and IFM apply a long-term average of forest carbon stocks. Once finalized, the tool must be used by all ARR and IFM projects. The tool will serve two primary functions:

1. It will determine if a project is required to apply a long-term average of forest carbon stocks.
2. Where a long-term average is required, it will provide the steps for determining the long-term average.

Use of the tool will enhance integrity by ensuring projects are only credited up to the estimated long-term average of forest carbon stocks while accounting for long-term gains from forest growth and losses due to harvesting.

• The proposed tool is being developed by Verra and is currently at “Step 3: Draft Methodology Development” of the VCS Methodology Development and Review Process (PDF).
• Stakeholders interested in collaborating during methodology development or developing projects that this tool might enable are encouraged to contact methodologies@verra.org. Please include the Methodology Development ID #M0405 in the subject line.
