Overview
- CARB posted proposed regulatory text for SB 253 and SB 261 and plans to open a 45-day public comment window on Dec. 26, closing Feb. 9, 2026.
- The CARB board will consider the rules at a public hearing on Feb. 26, with a possible continuation on Feb. 27 and a remote attendance option available.
- Under the SB 253 proposal, companies with over $1 billion in revenue would file scope 1 and scope 2 emissions by Aug. 10, 2026, using a revenue definition based on California gross receipts and the lesser of the prior two fiscal years.
- Nonprofits, government entities, insurers, firms limited to wholesale electricity purchases in California, and entities only paying teleworking employees in the state are excluded under the draft rules.
- Following a Ninth Circuit injunction, CARB will not enforce SB 261’s Jan. 1, 2026 deadline and has opened a voluntary filing docket, as business groups including the U.S. Chamber and ExxonMobil continue First Amendment challenges.
