ACR Validation and Verification Standard
The American Carbon Registry (ACR) requires independent third-party validation and verification of all carbon offset projects following ACR Validation and Verification Guidelines.
Verification is a risk-based process carried out in conformance with ISO 14064-3:2006 and ISO 14065:2007. ACR validation and verification bodies (VVBs) shall be accredited for project validation and verification and the scope of the applicable methodology, and VVB teams shall meet the competence requirements as set out in ISO 14065:2007. VVBs shall also be approved by ACR following the requirements detailed on the ACR webpage for Validation and Verification.
ACR is updating its validation and verification guidelines to the ACR Validation and Verification Standard. Stakeholders are invited to submit comments to ACR@Winrock.org by April 30, 2017.
