CARB To Extend Deadline for SB 253 Reporting in 2026 by Three Months

On June 24, 2026, CARB announced that it will be extending the 2026 deadline to report Scope 1 and Scope 2 GHG emissions pursuant to SB 253 by three months, from August 10, 2026, to November 10, 2026. 

As a reminder, SB 253 requires business entities organized under U.S. law, doing business in California, and with annual revenues over $1B to (1) starting in 2026, annually disclose their Scope 1 and 2 GHG emissions for the prior fiscal year and (2) starting in 2027, also annually disclose their Scope 3 GHG emissions for the prior fiscal year.

In the upcoming rulemaking, CARB also plans to clarify certain regulatory requirements, and has indicated that there will be a fifteen-day public comment period.

The rulemaking documents will be available on CARB’s rulemaking webpage.
