California SB 261 Climate Disclosure 2026: CARB Releases Draft Reporting Checklist

September 2, 2025: The California Air Resources Board (CARB) released a draft checklist to support companies in preparing their first climate-related financial risk reports under SB 261, also known as the Climate-Related Financial Risk Disclosure Program. These reports are due January 1, 2026, and must then be submitted biennially thereafter.

What’s New?

  • Draft Checklist Now Available: CARB’s checklist outlines the minimum content and structure required for SB 261 compliance. 
  • Public Docket Opens December 1, 2025: Covered entities must post the public link to their SB 261 report in CARB’s docket, which remains open through July 1, 2026. 
  • Subsidiary Reporting Clarified: Subsidiaries don’t need to issue separate reports if the parent’s consolidated report covers them. 
  • Framework Flexibility: Companies may align with TCFD (2017), IFRS S2, or another recognized regulatory or exchange-based framework. 
  • Fiscal Year Data Permitted: SB 261 does not mandate calendar-year data; companies may use their most recent and reliable data, including fiscal year reporting. 
  • Insurance Exemption: Entities regulated by the California Department of Insurance—or operating as insurers in any state—are exempt from this requirement. 
  • Scope 1, 2, and 3 Emissions: Disclosure of Scope 1–3 emissions is not required in the first reporting year, but it will become relevant for future reporting cycles. 

Why It Matters

  • Advance Guidance Provided: CARB’s checklist helps organizations plan before their first SB 261 submission, reducing compliance uncertainty. 
  • Boosts Transparency: The December public docket ensures climate risk reports are publicly accessible in one central location. 
  • Simplifies Multi-Entity Reporting: Consolidated reporting at the parent level reduces duplication and eases reporting burdens. 
  • Promotes Global Alignment: Accepting established frameworks encourages comparability with international standards. 
  • Practical Data Guidance: Allowing fiscal-year data offers companies flexibility and eases disclosure efforts. 
  • Targeted Exclusions: The insurance industry is excluded, focusing the program on intended sectors.
