Speaking Sustainability

On December 9, 2025, the California Air Resources Board (CARB) announced that it will convene a public hearing on February 26, 2026, to consider approving the adoption of regulations governing California’s climate-related disclosure statutes: SB 253 and SB 261.[1] CARB also published the proposed regulatory text, which we explore below.

On December 1, 2025, the California Air Resources Board (CARB) released an Enforcement Advisory clarifying that it will not enforce SB 261 against covered entities for failing to publish climate-related financial risk reports by the January 1, 2026, statutory deadline.¹

The California Air Resources Board (CARB) recently released a Draft Checklist to assist companies in preparing climate-related financial risk reports under Senate Bill 261, codified at California Health and Safety Code (HSC) § 38533. While the Checklist offers limited new guidance, it provides a useful roadmap for entities subject to reporting obligations, particularly entities that may not have prepared previously and/or published disclosures consistent with recommendations issued by the Task Force on Climate-related Financial Disclosures (TCFD).
