COP 27: Top News for the Second Day of Events

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).

In the ongoing legal challenge to California’s climate-disclosure statutes (SB 253 and SB 261, discussed here by Akin), the U.S. District Court for the Central District of California recently issued an Order on August 13 that denied plaintiffs’ motion for a preliminary injunction. That motion was filed by the U.S. Chamber of Commerce and other business and farming groups arguing the statutes violated their First Amendment rights. The Court found that the plaintiffs were unlikely to succeed on the merits of their claims.

On August 13, 2025, the U.S. District Court for the Central District of California denied a motion for preliminary injunction filed by a coalition of business groups seeking to halt implementation of California’s corporate climate disclosure laws—SB 253 and SB 261. Senate Bill 253 (SB 253 )¹ requires entities that do business in California and whose total annual revenue exceeds $1 billion to disclose Scope 1 and 2 greenhouse gas (GHG) emissions beginning in 2026 (covering 2025 data), and Scope 3 emissions beginning in 2027 (covering 2026 data). Senate Bill 261 (SB 261),² passed as part of the same Climate Accountability legislative package, requires entities that do business in California and whose total annual revenue exceeds $500 million to publicly disclose the business’s climate-related financial risks and measures taken to reduce or adapt to that risk online every two years, beginning in 2026.³

The European Parliament and Council reached a provisional agreement (i.e., a post-consultation, non-binding political deal in relation to the final text of a legislative proposal) to streamline the European Union’s (EU) Carbon Border Adjustment Mechanism (CBAM) on June 18, 2025. This is a key instrument to prevent carbon leakage and align trade policy with the EU’s climate goals. The changes are part of the EU’s broader sustainability legislative simplification package announced earlier this year. This proposal is intended to ease compliance burdens while maintaining the environmental integrity of the CBAM framework.
