Connect with a Verification Body

The verification bodies listed below are accredited by the ANSI National Accreditation Board (ANAB) and qualified to provide verification services for voluntary and early action projects under the Reserve’s program. Once a verification body has both completed the training requirements AND achieved its ISO 14065: 2007, ISO 14064-3: 2006, and IAF MD 6: 2009 accreditation, it may advertise that it is “recognized and qualified as a verification body for the Climate Action Reserve.” The list of ANAB-accredited Verification Bodies is available on ANAB’s website. The Reserve is also working with Entidad Mexicana de Acreditación, A.C. (EMA) in Mexico to accredit verification bodies to support the Mexico Forest Protocol.

Projects undergoing verification for ARB offset credits: Offset Project Operators must employ verification bodies that have been accredited by ARB in order to be issued offset credits under an ARB Compliance Offset Protocol. Early action projects hoping to transition credits to the Compliance Offset Program must undergo a subsequent regulatory verification of Early Action Offset Credits (EAOCs) by an ARB-accredited verifier as well. Please consult the ARB website for the list of accredited offset verifiers and verification bodies.

Verification bodies that are currently undergoing the ANAB accreditation process and have not yet completed the process are allowed to perform verification activities for Reserve projects if they have already met the training requirements. However, CRTs will not be issued to those projects until the verification body has received its formal accreditation. The verification body should notify the project developer of the circumstances surrounding its expected accreditation and this should be addressed in its verification contract.

If a verification body is having trouble locating a client for an ANAB witness assessment, it should notify the Reserve staff at (213) 891-1444 ext. 3 or [email protected].

Note that verification bodies must have two or more lead verifiers trained on each project type for which they wish to perform verifications. Verification bodies interested in subcontracting verifiers may refer to the list of individual verifiers who have passed our project protocol-specific trainings. Note that the subcontracted verifier(s) must be identified on the Verification Policies Acknowledgement, Agreement, and Verification Staff Reporting Form and the NOVA/COI form. These verification body forms can be found on our Program-wide Project Forms page.
