Alongside SB 253, California Senate Bill 261 (SB 261)—the Climate-Related Financial Risk Act—mandates biennial climate financial disclosures for all commercial entities operating in California with annual revenues exceeding $500 million, codifying Task Force on Climate-related Financial Disclosures (TCFD) principles into statutory state law.

Core Compliance Thresholds

Covered entities must prepare and publicly publish a comprehensive Climate-Related Financial Risk Report on their official website on or before January 1, 2026, and biennially thereafter. The report must detail material financial risks arising from climate change and the operational measures adopted to mitigate and adapt to such risks.

1. The Four Pillars of SB 261 Climate Financial Risk

SB 261 explicitly requires disclosure structured around the recommendations of the Task Force on Climate-related Financial Disclosures (now monitored by the IFRS Foundation and ISSB Standard IFRS S2):

  • Governance: Board oversight of climate-related risks and management’s role in assessing climate vulnerability.
  • Strategy: Actual and potential impacts of climate risks and opportunities on business operations, supply chains, and financial capital allocation.
  • Risk Management: Organizational processes for identifying, assessing, and integrating climate risks into enterprise risk management (ERM) frameworks.
  • Metrics & Targets: Key operational indicators used to manage physical asset exposure and regulatory transition risks.
