The Latest on California’s Climate Disclosure Laws (SB 253 & SB 261)

October 31, 2025

Reading Time : 1 min

Despite litigation challenges and regulatory delays, deadlines are not shifting for reporting under California’s Climate Disclosure laws. Most recently, California Air Resources Board (CARB) delayed publishing draft regulations for SB 253 and SB 261, citing extensive public comments and ongoing input on covered entities. Despite the fact that CARB expects to publish an updated timeline for final regulations in early 2026, inaugural reporting under SB 261 is due by January 1, 2026.

In this video, we break down what the laws require and how to prepare for compliance.

Companies can:

✔ Establish or expand cross-functional teams to prepare for internal data collection, reporting and disclosure

✔ Document reporting processes and procedures to take advantage of CARB’s “good faith” transition policy

✔ Engage with external assurance providers early to understand what documentation, controls and systems will be required to meet the escalating assurance requirements

✔ For companies subject to SB 253, begin tracking and documenting Scope 1, 2, and 3 emissions

✔ Monitor CARB’s rulemaking process and weigh the value of submitting comments.

The California Air Resources Board (CARB) recently finalized a narrowly crafted, initial set of implementing regulations (Regulations) for California’s climate‑reporting statutes (i.e., SB 253 greenhouse gas (GHG) emissions reporting) and SB 261 (climate‑related financial risk disclosures).1 As adopted, the Regulations largely mirror the proposal issued in December 2025, without material changes. The Regulations provide a limited set of foundational compliance mechanics, but defer many consequential issues to future rulemaking initiatives, particularly in relation to how Scope 3 GHG emissions are to be reported under SB 253.

On February 18, the U.S. Environmental Protection Agency (EPA) issued its final rule repealing the greenhouse gas (GHG) “endangerment finding.” EPA’s leadership has characterized the repeal as a return to a narrower reading of the statute in light of scientific, technological and policy developments since 2009. The move significantly attempts to reshape the federal climate regulatory landscape and promptly drew legal challenges.
