California Air Resources Board

What California Air Resources Board does

The California Air Resources Board (CARB) is a state government regulatory agency established in 1967 under the Kishiyama Act, operating as one of six boards under the California Environmental Protection Agency (CalEPA). Headquartered in Sacramento with a Southern California office in Riverside, CARB employs 501-1,000 staff and partners with 35 local air districts covering all California counties. Its mandate is to attain and maintain health-based air quality standards, oversee all air pollution control in California, and serve as the lead agency for the state's climate change programs, serving the state's ~40 million residents, more than 4,000 US companies subject to corporate climate disclosure under SB 253/SB 261, industrial polluters participating in the Cap-and-Invest program covering 80% of state climate emissions, and commercial fleet operators subject to zero-emission mandates.

CARB's core operational platforms include the Cap-and-Invest (cap-and-trade) carbon market — one of the world's largest, with $35 billion in lifetime climate investments, 500,000+ funded projects, 30,000 supported jobs, and quarterly joint auctions with Quebec — together with the SB 253 corporate climate disclosure reporting infrastructure, the HVIP and California Clean Fuel Rewards voucher programs deploying $1 billion in electric truck rebates, the Advanced Clean Cars/Trucks/Fleets regulatory frameworks driving a cumulative 2.5 million+ ZEV sales in California (18.9% of new-car sales in Q4 2025), and a statewide air quality monitoring network spanning 26 air districts. Supporting technology includes the ARBER equipment registration system, the Cap-and-Trade auction registry, the Natural and Working Lands Carbon Inventory (4,953 MMT stored as of 2022), and 216,523 charging and hydrogen fueling stations tracked across the state. 17 states plus California have adopted CARB vehicle emissions standards, representing approximately 40% of US new-vehicle sales.

As a non-commercial regulator, CARB generates no traditional revenue. Funding comprises California state budget appropriations, Cap-and-Invest allowance auction proceeds (the 47th joint auction alone generated approximately $770 million at $28-$29 per allowance), regulatory fees under SB 253 ($2,000-$7,000 per in-scope entity annually across 4,000+ US companies), enforcement settlements (including approximately $197 million from Volvo Group North America and $56,250 from Disneyland's Autopia program), and dedicated incentive funding from the Low Carbon Fuel Standard. Programs are delivered through direct government operations, third-party administrators (Southern California Edison for Clean Fuel Rewards; CALSTART for HVIP), and strategic partnerships with the Port of Los Angeles, Port of Long Beach, and Harbor Breeze Cruises for maritime emission reductions. The agency's value proposition rests on unique statutory authority under Clean Air Act Section 209 to set stricter-than-federal vehicle emission standards, comprehensive emissions data infrastructure, and globally recognized regulatory leadership under Chair Lauren Sanchez (appointed September 2025).

Broad incumbents

• U.S. Environmental Protection Agency (EPA): The federal counterpart to CARB for air quality and climate regulation under the Clean Air Act. EPA sets baseline national vehicle and industrial emission standards, grants Section 209 waivers to California, and is currently in active legal conflict with CARB over waiver authority — making it the most direct federal regulatory peer.
• New York State Department of Environmental Conservation: A state-level environmental regulator with broad jurisdiction over air quality, water, and waste — comparable to CARB at the state level. New York has adopted California's ZEV mandate and participates in cap-and-trade discussions, making it the most analogous state-level peer outside California.
• Texas Commission on Environmental Quality: Texas's primary environmental regulator with jurisdiction over air quality, water, and waste at the state level. Unlike CARB, it has not adopted California's ZEV mandates, but it represents a comparable state-level environmental regulatory body — illustrating the policy divergence that exists between CARB-aligned and non-aligned states.

Direct peers

• South Coast Air Quality Management District: The largest of California's 35 local air districts, covering the Los Angeles metropolitan area (the most ozone-polluted region in the US). Like CARB, it conducts air quality monitoring, stationary source permitting, and regional air quality planning — but at a more localized level and with delegated authority from CARB.
• Bay Area Air Quality Management District: Another major California air district covering the nine-county San Francisco Bay Area. It shares CARB's air quality monitoring and stationary source permitting responsibilities at a regional scale and operates under CARB's regulatory framework.
• San Joaquin Valley Air Pollution Control District: California air district covering eight counties in the Central Valley, an area with some of the worst air quality in the US and a focus of CARB's environmental justice work under AB 617. Shares CARB's regulatory and monitoring responsibilities at a regional level.

Regional players

• Oregon Department of Environmental Quality: Oregon's state environmental agency that has adopted California's Advanced Clean Cars and Advanced Clean Trucks rules. It mirrors CARB's regulatory model in a neighboring jurisdiction and represents one of the 17 states following CARB standards.
• Washington State Department of Ecology: Washington's primary environmental regulatory agency, which has adopted California's vehicle emissions standards under Section 177 of the Clean Air Act. Comparable to CARB in mandate and policy direction, but operating at the state level in the Pacific Northwest.
• Quebec Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs: Quebec's provincial environmental regulator and CARB's direct partner in the joint Cap-and-Invest allowance auctions — the largest carbon market linkage in North America. Operates the Western Climate Initiative cap-and-trade system alongside California.
• European Environment Agency (EEA): The EU's environmental information agency, providing comparable air quality monitoring, emissions data, and climate reporting across European member states. Operates as a regulatory counterpart at a supranational level, with similar scope to CARB's environmental quality program administration mandate.
