Greenhouse Gas Emissions Verification

This page last modified May 9, 2012

The Regulation for the Mandatory Reporting of Greenhouse Gas Emissions requires the reporting and verification of greenhouse gas (GHG) emissions.  Beginning in 2010, for their 2009 reported emissions, reporting entities are required to have their GHG emissions verified.  In order to maintain their ARB accreditation, all verifiers must take ARB verifier training, and be re-accredited.  Only the following ARB accredited verification bodies and verifiers may provide verification services.

Accreditation and Oversight

ARB has established and implemented a verification program to support GHG reporting.  Two primary components are an accreditation program for GHG verification bodies and verifiers, and a verifier performance oversight program.  Summary of ARB's Accreditation and Verification Oversight.

ARB is responsible for evaluating the verification services provided by ARB-accredited verification bodies and verifiers to ensure California's high quality standards are achieved.  More about Verification and Audits.
