CA Air Resources Board

California GHG Reporting and Climate Financial Risk Disclosure Initial Regulation Adopted

The California Air Resources Board adopted the California Greenhouse Gas Reporting and Climate Financial Risk Disclosure Initial Regulation on February 26, 2026, establishing fee structures and administration procedures for SB 253 and SB 261. The regulation sets the first-year reporting deadline under SB 253 as August 10, 2026, with reporting limited to Scope 1 and Scope 2 emissions. The rule applies to large corporations doing business in California with gross revenue exceeding $500 million or $1 billion depending on the statute.

Emergency Vehicle Emissions Regulation Permanently Adopted

The California Air Resources Board permanently adopted the Emergency Vehicle Emissions Regulations initially enacted in 2025 as a temporary measure. The permanent adoption responds to federal disapproval of California's waivers for Advanced Clean Cars II and Heavy-Duty Engine and Vehicle Omnibus regulations. The amendments confirm that earlier vehicle emissions standards remain in effect, providing manufacturers flexibility to certify to pre-ACC II and Omnibus emission standards while voluntarily complying with newer requirements.
