Overview
- A brief Ninth Circuit order issued November 18 enjoins enforcement of SB 261, which would have required inaugural climate‑risk reports on January 1, 2026.
- The order did not extend to SB 253, and CARB signaled an initial SB 253 reporting deadline of August 10, 2026, with rulemaking hearings expected early next year.
- The scope of the SB 261 injunction remains unclear because the court offered no explanation and the request referenced members of specific plaintiff organizations.
- Plaintiffs led by the U.S. Chamber withdrew their emergency application to the U.S. Supreme Court after the appellate stay was granted.
- CARB said it is reviewing the ruling, leaving companies uncertain about who must report and when disclosures may ultimately be required.
