On November 10, 2025, EPA released a proposed rule under the Toxic Substances Control Act (“TSCA”), proposing to amend its reporting requirements relating to per- and polyfluoroalkyl substances (“PFAS”).  The original rule, promulgated in 2023, led to concerns by some regulated entities that it would be difficult to collect the…

Last week, the California Legislature passed two bills comprising the core of a landmark “Climate Accountability Package.”  Together, the two bills will impose extensive new climate-related disclosure obligations on thousands of U.S. public and private companies with operations in California.  Senate Bill 253 (SB 253) would require companies with greater than $1 billion in annual revenues to file annual reports publicly disclosing their Scope 1, 2 and 3 greenhouse gas (GHG) emissions.  Senate Bill 261 (SB 261) would require companies with greater than $500 million in annual revenues to prepare biennial reports disclosing climate-related financial risk and describing measures adopted to mitigate and adapt to that risk.

Yesterday afternoon during an appearance at Climate Week NYC, Governor Newsom told the audience emphatically, “of course I will sign those bills.”  When he does, many more companies will be required to improve the accuracy, completeness and rigor of their GHG reporting and climate risk disclosures. Because of the complexity of GHG reporting, we have focused the remainder of this post on SB 253.  Please see our separate post on SB 261 here.Continue Reading California Legislature Passes Landmark Climate Disclosure Laws: Spotlight on SB 253

Last week, the California Legislature passed two bills as part of the state’s landmark “Climate Accountability Package.”  If signed by Governor Newsom as anticipated, the two laws—Senate Bill 253 (SB 253) and Senate Bill 261 (SB 261)—will usher in significant climate-related disclosure requirements for thousands of U.S. public and private companies that do business in California.

SB 253 and SB 261 mark the most extensive emissions- and climate-disclosure laws enacted in the United States to date.  SB 253 requires companies with greater than $1 billion in annual revenues to file annual reports publicly disclosing their direct, indirect, and supply chain greenhouse gas (GHG) emissions, verified by an independent and experienced third-party provider.  SB 261 requires companies with $500 million in annual revenues to prepare biennial reports disclosing climate-related financial risk and measures they have adopted to reduce and adapt to that risk, with the first report due by January 1, 2026.

This post focuses on SB 261’s climate-related financial risk disclosure requirements. You can find our post on SB 253’s GHG emissions reporting requirements here.Continue Reading California Legislature Passes Landmark Climate Disclosure Laws: Spotlight on SB 261

On 26 June 2023, the International Sustainability Standards Board (“ISSB”) published its inaugural International Financial Reporting Standards Sustainability Disclosure Standards (the “ISSB Standards”) (read our previous blog post on this here).  In August 2023, the UK Financial Conduct Authority (“FCA”) published Primary Market Bulletin 45, confirming its intentions to update its climate-related disclosures for listed companies under the Listing Rules (see LR 9.8.6 R (8) and LR 14.3.27 R) to reference UK-endorsed ISSB Standards.Continue Reading Corporate Reporting in the UK: The International Sustainability Standards Board

On 26 June 2023, the International Sustainability Standards Board (the “ISSB”) issued its inaugural International Financial Reporting Standards (“IFRS”) Sustainability Disclosure Standards (the “Standards”), heralding progress in the development of a global baseline of sustainability-linked disclosures. The Standards build on the concepts that underpin the IFRS Accounting Standards, which are required in more than 140 jurisdictions, but notably not in the United States for domestic issuers subject to regulation by the Securities and Exchange Commission (“SEC”), which must apply US Generally Accepted Accounting Principles (“US GAAP”).  Despite broad investor appetite for  transparent, uniform and comparable disclosure rules, the scope of required sustainability disclosure and timing for adoption of the SEC’s pending climate disclosure rule remains unresolved.Continue Reading ISSB Issues Inaugural Global Sustainability Disclosure Standards

The Greenhouse Gas Protocol (“GHG Protocol” or “Protocol”)—a leading standard setter for measuring and managing corporate greenhouse gas emissions, borne of a partnership between World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD)—has opened stakeholder surveys concerning the revision of its Corporate Accounting and Reporting Standard, Guidance on Scope 2 Emissions, and the Scope 3 Standard and Scope 3 Calculation Guidance.Continue Reading Corporate Carbon Counting Under Scrutiny—Comments Requested on Pending Updates to the Greenhouse Gas Protocol
