As the SEC Gears Up for Mandatory Climate Disclosure, So Does California

Feb 25, 2021

Reading Time : 3 min

California Senate Bill 260 (SB 260), entitled the Climate Corporate Accountability Act, would direct the California Air Resources Board (CARB) to develop requirements for corporations with more than $1 billion in revenue that do business in California to disclose their scope 1, 2 and 3 greenhouse gas emissions in annual reports beginning no later than January 2024. By 2025, those corporations would have to begin publishing “science-based” emissions targets consistent with the Paris Agreement’s aspirations to limit global warming to no more than 1.5 degrees Celsius above preindustrial levels.

While many large companies already issue climate disclosures on a voluntary basis, SB 260 would no longer give them—or their more reluctant peers—a choice. Importantly, the bill’s required scope 2 and 3 emissions reporting would force companies to disclose, for the first time, the indirect emissions that result from their purchase and use of electricity as well as their supply chains, business travel, procurement efforts, water use and wastes. Covered entities also would have to engage certified third-party auditors to verify their disclosures and emissions targets, another noteworthy first that should lead to a greater degree of standardization over time in climate reporting. Given the bill’s capacious reach and the minimum contacts with California required to trigger its applicability, most large companies in virtually every sector would soon face climate disclosure requirements.

By contrast, the SEC’s current federal disclosure regulations, such as Regulation S-K, require neither emissions accounting nor target setting. Instead, companies have discretion to consider and report only on issues they deem “material” under the current principles-based approach to disclosure. Simply put, SB 260, if enacted, would revolutionize the U.S. regulatory disclosure landscape in under three years, and possibly pave the way for more robust disclosure in other ESG areas over time. These requirements might exceed those that a Gensler-led SEC will impose and could encourage other states to adopt similar systems to supplement or fill the gaps left by the federal regime.

With that said, the bill is not without other political and legal restraints, and it is not on a surefire path toward enactment. Although supported by a number of prominent environmental organizations, like the California League of Conservation Voters, the bill’s somewhat vague definition of “science-based emissions target” has the potential to govern direct and indirect greenhouse gas emissions anywhere a covered entity operates, even places beyond California’s borders. This broad ambit could conflict with the U.S. Constitution’s Commerce Clause, and may give pause to California legislators and greenhouse gas regulators. 

Opponents likely will argue that existing California laws already impose comparable requirements on a number of regulated entities. These laws—such as Assembly Bill 32, and Senate Bills 32, 350 and 100—require companies with direct, in-state greenhouse gas emissions exceeding 10 million metric tons per year to report and reduce those emissions according to CARB targets. Currently, many sectors face these requirements, including the energy, electricity generation, transportation, cement, chemical, and agriculture sectors. In addition, California has set ambitious emissions reductions goals governing the generation and sale of electricity, including a requirement that 100 percent of retail electricity sales come from renewable energy sources by 2045. Similarly, 40 percent of truck engine sales in the state by 2045 must consist of zero-emission models, and other regulations impose (or soon will impose) some form of reporting and reduction requirements on companies doing business in California. Thus, to some extent, SB 260 may be duplicative, overly burdensome, and of marginal benefit when considered against the backdrop of California’s current regulatory environment. For these reasons, the measure could face resistance from moderate members of the Democratic caucus.

The bill will face its first test as early as next month in the State Senate’s Environmental Quality and Judiciary Committees. If it clears both committees and the State Senate, it then must pass the State Assembly, after which point it likely would receive the Governor’s approval as early as this fall. It also remains to be seen whether the SEC’s eventual federal disclosure requirements supersede, or merely set the floor for, these potential California-specific requirements.

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.
