CARB Climate Programs
Navigate the requirements of the California Air Resources Board (CARB) with confidence. From reporting preparation to accredited third-party verification, our expert guidance helps ensure accuracy, compliance, and market integrity.
Overview and Impact on Regulated Entities
The California Air Resources Board (CARB) administers one of the nation’s most comprehensive climate regulatory programs, focused on reducing greenhouse gas emissions and ensuring environmental accountability across regulated sectors. A core component of these programs is mandatory third-party verification, requiring CARB-accredited verification bodies to independently assess the accuracy, completeness, and compliance of reported data. Programs such as the Mandatory GHG Reporting Regulation (MRR), Low Carbon Fuel Standard (LCFS), and Cap-and-Trade rely on verified data to maintain market integrity and regulatory confidence.
Standard Carbon is a CARB-accredited verification body, delivering independent, technically rigorous verification services with clarity, efficiency, and regulatory precision.
Frequently Asked Questions
Overview of CARB Verification
What is CARB’s verification program?
CARB’s verification programs are regulatory frameworks requiring independent third-party verification of emissions and data reports under key California climate and emissions programs (e.g., Mandatory GHG Reporting (MRR), Low Carbon Fuel Standard (LCFS), Cap-and-Trade/Offset, and other CARB programs). The purpose is to ensure accuracy, quality, and regulatory compliance of reported data.
Why is verification needed?
Verification ensures that emissions and other mandated data meet CARB’s strict accuracy standards and that independent verification bodies provide consistent, credible evaluations required under state law and regulation.
Who can conduct CARB-required verification?
Only CARB-accredited verification bodies and CARB-accredited individual verifiers may perform regulatory verification services for reporting entities subject to CARB verification requirements.
What reports must be verified?
Entities subject to CARB’s programs (e.g., MRR/Greenhouse Gas Reporting, LCFS, Cap-and-Trade/Offsets) must submit reported data that is independently verified by a CARB-accredited verification body. Examples include:
- GHG emissions inventories under the MRR.
- Fuel and emissions data under the LCFS.
- Offsets/GHG reductions for Cap-and-Trade compliance.
What is a verification statement?
A verification statement is a formal document submitted by the accredited verification body confirming that the emissions or data report has been independently verified according to applicable CARB requirements.
Are U.S. EPA verifications accepted by CARB?
No — verification by U.S. EPA does not automatically satisfy CARB verification requirements, though coordination may help streamline dual agency compliance.
Accreditation, Training & Conflicts of Interest
What are the accreditation requirements for verification bodies?
Verification bodies must apply for CARB accreditation, demonstrate sufficient staffing and technical capacity, and comply with CARB’s criteria specific to the program they will verify under (e.g., MRR, LCFS, offset). Accreditation ensures that the body maintains competence and independence.
What training is required for CARB verification accreditation?
CARB conducts verifier training for certain programs (e.g., MRR). Accredited bodies and individuals must complete relevant CARB-approved training to ensure familiarity with verification procedures and regulatory expectations. Training schedules and requirements are posted by CARB and updated periodically.
Do verifiers need to be reaccredited?
Yes. Individual verifiers must apply for reaccreditation on a periodic basis (e.g., every three years under MRR) to maintain their accredited status.
Is there unique training for offset verifiers?
Yes, CARB typically requires verifiers to complete program-specific training (e.g., Compliance Offset Protocol training) and examinations demonstrating competency in the relevant methodologies and procedures.
What conflict of interest rules apply?
Verification bodies and auditors must disclose and manage conflicts of interest as part of CARB’s accreditation and verification process, ensuring objectivity in verification services.
Program Specific Verification
When is verification due?
Verification timing is program-specific. Under the MRR regulation, entities must have their GHG emissions reports verified annually by the specified deadline (e.g., typically August 10 for MRR reports).
What does MRR verification cover?
Independent verification of reported greenhouse gas emissions in accordance with CARB’s MRR regulation (Title 17 CCR 95100-95157) is required for entities meeting reporting thresholds.
How is MRR verification performed?
Verification bodies assess emissions reports for completeness, accuracy, and conformance with the regulation and guidance, then issue a verification statement confirming the acceptability of the data.
What LCFS data requires verification?
Data defined under LCFS (e.g., fuel carbon intensity scores, pathway reports) must be independently verified by a CARB-accredited verification body.
Where can I find LCFS verification guidance?
CARB publishes Annual Reporting and Verification User Guides, training details, and LCFS-specific FAQ resources on its official LCFS verification webpages.(California Air Resources Board)
Are offset projects subject to verification?
Yes. Projects generating compliance offsets require regulatory verification by accredited bodies. Offset verification involves additional requirements like Notice of Offset Verification Services (NOVS) and conflict of interest submissions before verification work begins.
Program Specific Verification
What must the verifier provide to CARB?
The verification body submits documentation demonstrating completion of verification, including conflict-of-interest assessments, verification statements, and any required forms as specified by the program.
How does a reporting entity prepare for verification?
Entities should ensure their data systems, methods, calculation documentation, and reporting conform with the applicable regulation (e.g., MRR, LCFS) and coordinate early with an accredited verification body to address potential issues before the verification deadline.
Where can questions about CARB verification be directed?
Each program’s CARB verification webpage lists contact emails for verification questions, such as:
- MRR verification questions: ghgverify@arb.ca.gov.(California Air Resources Board)
- LCFS verification questions: lcfsverify@arb.ca.gov.(California Air Resources Board)
Other programs (e.g., offset verification) have similar contact information on CARB webpages.(California Air Resources Board)
