ACR Announces Public Comment Period for Updated Improved Forest Management (IFM) Methodology

The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, is soliciting public comments on an updated version 2.0 of its approved Methodology for the Quantification, Monitoring, Reporting and Verification of Greenhouse Gas Emissions Reductions and Removals from Improved Forest Management in Non-Federal U.S. Forestlands.  

Similar to previous versions of the Methodology, greenhouse gas emission reductions are quantified from forest carbon projects that reduce emissions by exceeding baseline forest management practices, and removals are quantified for increased sequestration through retention of annual forest growth.

A detailed list of Methodology updates can be found in the “Summary of Proposed Modifications for IFM v2.0”.

The Methodology update was developed by ACR over the last year, based on learnings from projects registered under a version of the Methodology, authored by Matt Delaney and David Ford of L&C Carbon and Greg Latta of Oregon State University and originally developed by Finite Carbon. The Methodology is being updated through ACR’s public consultation and scientific peer review processes.

Please send comments to, referencing “comments to IFM update,” by October 20, 2021.
