California climate rules cause uncertainty as CARB delays draft guidance

California Air Resources Board

California has delayed the release of draft greenhouse gas reporting rules for businesses until early 2026, the California Air Resources Board (CARB) said.

The California regulations have been underway since 2023, when Gov. Gavin Newsom signed two climate bills into law, SB 253 and SB 261. The laws will require more than 3,100 large companies to publicly report their greenhouse gas emissions (GHG), in a push by the state to reduce health-sapping air pollution and the carbon emissions that fuel global warming.

The California laws and similar ones in New York are still standing despite coming under fire by the Trump administration. Requirements that were coming online at the Securities and Exchange Commission (SEC) for businesses to make climate-related disclosures were yanked by the Trump administration.
