LCFS Verification

CARB's LCFS, which appears at sections 95480 to 95503 of title 17, California Code of Regulations, requires independent verification of data reports specified in section 95500. Verification questions may be sent to lcfsverify@arb.ca.gov.

Background

The LCFS is designed to decrease the carbon intensity of California's transportation fuel pool and provide an increasing range of low-carbon and renewable alternatives, which reduce petroleum dependency and achieve air quality benefits. The LCFS relies on accurate data monitoring, reporting, and verification to support implementation and tracking of effectiveness. In 2018, the Board approved amendments to add third-party verification requirements to the LCFS to ensure data completeness, accuracy, and conformance with the regulation – consistent with the verification programs under California’s Cap-and-Trade Program and international best practices. The LCFS verification program, under CARB oversight, provides confidence and reliability in reported data for stakeholders, market participants, and the public.

Verification services are performed by qualified and trained verifiers that meet specifications for education and experience and demonstrate that there is no conflict of interest for verifying the reported data due to current or previous relationships with the LCFS regulated entity. CARB verification forms and ongoing accreditation and verifier training information is provided below, under Information for Verifiers. The list of verifiers and verification bodies accredited by CARB is posted below, under Information for Entities Required to Engage Verifiers.
