Get Ready for California Climate Disclosure
California Sets the Standard in Climate Transparency
California has passed two groundbreaking climate disclosure laws that will transform how companies report on sustainability:
- SB 253 – Climate Corporate Data Accountability Act
Companies with over $1 billion in annual revenue doing business in California must disclose Scopes 1, 2, and 3 greenhouse gas emissions, verified by third-party assurance providers. - SB 261 – Climate-Related Financial Risk Act
Companies with over $500 million in annual revenue must file public reports on climate-related financial risks and the strategies in place to mitigate those risks.
With California ranked as the 4th largest economy in the world, these laws are more than state policy — they are setting a national and global benchmark for climate accountability.
Key Deadlines You Can’t Ignore
2026
Report Scope 1 & 2 emissions for FY2025 with limited assurance
2027
Report Scope 3 emissions for FY2026 across your value chain.
2030
Obtain reasonable assurance for Scope 1 & 2, and limited assurance for Scope 3.
