California SB 261 – Climate-Related Financial Risk Act
California law requiring US-based companies with more than $500 million in annual revenue that do business in the state to publish a climate-related financial risk report every two years, following the TCFD framework or an equivalent. The Ninth Circuit enjoined enforcement while the Chamber of Commerce appeal is pending, so CARB has not enforced the 1 January 2026 deadline. Companies may post reports voluntarily to a CARB docket opened 1 December 2025.
- Enforcement
- Mandatory by statute; enforcement suspended by court injunction
- Effective date
- Statutory first report due 1 January 2026 and every two years after; CARB is not enforcing that date and will announce an alternate reporting date after the appeal is resolved
- Covered entities
- US companies doing business in California with revenue >$500m
