SB 253 mandates that thousands of US public and private companies with annual revenue over $1 billion and operating in California must publicly disclose their full GHG emissions (Scope 1, 2, and 3).
SB 261 requires US public and private companies with annual revenue over $500 million and operating in California to prepare biennial reports disclosing their climate-related financial risks and the measures they are taking to mitigate those risks. This is aligned with the TCFD framework.
SB 253 Scope 1 & 2 Reporting: Begins in 2026 and must be based on the prior fiscal year (2025).
SB 253 Scope 3 Reporting: Begins in 2027 must be based on the prior fiscal year (2026).
SB 261 Climate Risk Reporting: Biennial reports begin in 2026.
Companies may face steep penalties up to $500,000 annually for non-compliance. Ensuring audit-ready data and transparent disclosure is critical to mitigate this financial exposure.
