  • U.S. Appeals Court Continues Pause on Litigation of SEC Climate-Relate Disclosure Rule

The Details

The U.S. District Court for the Western District of Texas entered a preliminary injunction against Texas Senate Bill 2337 (SB 2337) one day before the bill’s effective date. The bill would have regulated proxy advisory firms on their diversity, equity and inclusion (DEI)- and ESG-related investment recommendations and disclosures.

  • The bill, meant to take effect September 1, was intended to limit the use of DEI- and ESG-related considerations at proxy advisory firms by requiring financial analysis supporting its advice and to publicly disclose that such advice does not solely serve shareholders’ financial interests.
  • Institutional Shareholder Services (ISS) and Glass Lewis brought separate lawsuits, arguing the law unconstitutionally restricted their speech and interfered with the Employee Retirement Income Security Act (ERISA).
  • The court agreed with the proxy firms’ arguments that the bill “discriminates based on viewpoint” and compels firms to adopt the government’s stance on contentious issues.
  • Texas Attorney General Ken Paxton has announced that his office will be appealing the preliminary injunction orders. A trial on the merits is currently scheduled to begin in February 2026.

The Environmental Protection Agency (EPA) released a proposed rule that would significantly scale back the Greenhouse Gas Reporting Program (GHGRP) and eliminate reporting requirements for all source categories except Petroleum and Natural Gas Systems (Subpart W).

  • The agency maintains that the Clean Air Act does not require collection of greenhouse gas data outside of Subpart W (excluding distribution). EPA will consider separate petitions for reconsideration of Subpart W in a different rulemaking.
  • The proposal would relieve approximately 8,200 facilities across various sectors (e.g., cement, power generation, electronics, ferroalloy production and solid waste landfills) of current reporting obligations.
  • Comments regarding the proposed rule are due by November 3, 2025.

The U.S. Court of Appeals for the 8th Circuit issued an order on September 12 continuing to hold in abeyance the litigation over the agency’s Biden-era climate-related disclosure rule.

  • The order emphasizes that the Securities and Exchange Commission (SEC) must either defend the disclosure rule in court or conduct a rulemaking process to rescind or revise it.
  • SEC commissioners voted in March 2025 to cease defending the rule and had asked the court to proceed with clarifying the agency’s rulemaking authority. Akin discussed that development here.

The court rejected SEC’s approach, holding the case in abeyance “to promote judicial economy” until SEC chooses a path forward. Akin will continue monitoring developments

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.
