These laws will impact thousands of companies doing business in the state, requiring them to disclose greenhouse gas (GHG) emissions and climate-related financial risks.
Understanding the nuances of California SB 253 and SB 261 is crucial for affected businesses to ensure compliance and strategically navigate this new regulatory landscape.
Unpacking California SB 253: The Climate Corporate Data Accountability Act
SB 253 mandates comprehensive greenhouse gas emissions reporting for large companies operating in California. Its primary aim is to increase transparency regarding corporate carbon footprints.
What is SB 253?
At its core, SB 253 requires companies with total annual revenues exceeding $1 billion (USD) that do business in California to publicly disclose their Scope 1 (direct emissions), Scope 2 (indirect emissions from energy consumption), and Scope 3 (indirect emissions from supply chains) GHG emissions. These disclosures must align with the Greenhouse Gas Protocol standards.
Key Requirements and Deadlines:
- Affected Entities: Public and private companies with over $1 billion in annual revenue doing business in California.
- Reporting Scope: Annual disclosure of Scope 1, Scope 2, and Scope 3 GHG emissions.
- Timeline:
- 2026: Reporting for Scope 1 and Scope 2 emissions (based on 2025 data) begins.
- 2027: Reporting for Scope 3 emissions (based on 2026 data) begins.
- Verification: Emissions reports will require third-party assurance, starting with limited assurance and transitioning to reasonable assurance for Scope 1 and 2 emissions by 2030.
- Penalties: Non-compliance can lead to penalties of up to $500,000 per reporting year.
SB 253 aims to provide stakeholders with consistent and reliable data on corporate emissions, fostering accountability and driving emissions reductions.

Understanding California SB 261: The Climate-Related Financial Risk Act
Complementing SB 253, SB 261 focuses on the financial risks that climate change poses to businesses. This act mandates disclosure of these risks and the strategies being implemented to mitigate them.
What is SB 261?
SB 261 requires companies with total annual revenues exceeding $500 million USD doing business in California to prepare and publicly disclose biennial (every two years) reports on their climate-related financial risks. These reports should follow the framework recommended by the Task Force on Climate-Related Financial Disclosures (TCFD).
Key requirements and deadlines:
- Affected Entities: Companies (corporations, partnerships, LLCs) with over $500 million in annual revenue doing business in California.
- Reporting Scope: The biennial disclosure of climate-related financial risks and measures taken to reduce and adapt to these risks is aligned with TCFD recommendations.
- Timeline: The first report is due by January 1, 2026.
- Oversight: The California Air Resources Board (CARB) will contract an organization to review reports and provide an analysis of systemic and sector-wide risks.

SB 261 aims to ensure that businesses proactively identify, assess, and manage climate change's financial implications.
