California's Corporate Climate Data Accountability Act: Navigating SB 253, SB 261, and SB 219

Aug 15, 2025 Sustainability

California has set a high bar for climate policy, leading the charge with ambitious laws on greenhouse gas emission reporting and climate resilience. This guide breaks down the key legislation in the state's "Climate Accountability Package"—Senate Bills (SB) 253, 261, and the foundational discussions of SB 219—each designed to enhance corporate transparency and accountability. 

For companies doing business in California, keeping up with these regulations is crucial not only for compliance but also for managing strategic risks, maintaining investor trust, and contributing to a sustainable economy. As a global leader in safety solutions, we offer expertise and guidance to help you navigate these complex regulations with confidence. 

Understanding the Climate Corporate Data Accountability Act (SB 253)

The Climate Corporate Data Accountability Act, or SB 253, is a pivotal shift in how companies report environmental impacts in the U.S. This law requires transparency in greenhouse gas (GHG) emissions reporting, impacting thousands of businesses.
Coverage and Requirements of SB 253
Revenue Requirement
GHG Emission Scopes
Assurance Timeline 
Public & Private Companies $1 billion or more annually
Scope 1, Scope 2, Scope 3 
2026: Scope 1 & 2 Reporting
2027: Scope 3 Reporting

Navigating the Climate-Related Financial Risk Act (SB 261)

SB 261 builds on SB 253 by requiring businesses to disclose climate-related financial risks, addressing the broader impact of climate change on operations and strategy.
This bill would require, on or before January 1, 2026, and biennially thereafter, a covered entity, as defined, to prepare a climate-related financial risk report disclosing the entity's climate-related financial risk and measures adopted to reduce and adapt to climate-related financial risk. The bill would require the covered entity to make a copy of the report available to the public on its website.
Key Provisions of SB 261
Covered Entities
Revenue Threshold
Financial Risk Reporting
Reporting Schedule
Public & Private Companies $500 million or more annually
Physical & Transition Risks
TCFD Alignment

Clarifying SB 219: The Legislative Pathway

Though not enacted, SB 219 played a significant role in the amendment of California's climate accountability framework. Its elements ultimately informed SB 253 and SB 261.
Role of SB 219
While it aided in shaping the legislative discourse, companies should focus on SB 253 and SB 261 to understand current requirements and timelines.
This bill would delay the requirement that the state board adopt regulations until July 1, 2025. It would require that the regulations adopted by the state board require, among other things, a reporting entity to make the annual disclosure to either the emissions reporting organization or the state board, and that the reporting entity publicly disclose its scope 3 emissions on a schedule specified by the state board, rather than no later than 180 days after its scope 1 emissions and scope 2 emissions are publicly disclosed.
The bill would authorize reports to be consolidated at the parent company level and would delete the requirement that the annual fee be paid upon filing the disclosure. The bill would authorize, rather than require, the state board to contract with an emissions reporting organization to develop a reporting program to receive and make certain required disclosures publicly available. The bill would make other related changes to the duties of the emissions reporting organization and the state board, as provided.
