About this article

This article explains California's SB 253 and SB 261 climate disclosure laws and their global implications for corporate transparency. It offers a roadmap for companies to get ahead of compliance.

Global Impact of California SB 253 and SB 261

California, a global leader in environmental policy, has taken a significant step towards a more sustainable future with the passing of SB 253 and SB 261, also known as the Climate Accountability Package. They present both significant opportunities and considerations for Consumer Packaged Goods companies operating in California.

Increased Transparency

SB 253, the Climate Corporate Data Accountability Act, mandates increased transparency for large companies (over $1 billion in annual revenue) doing business in California. Starting in 2026, these companies will be required to disclose their greenhouse gas (GHG) emissions annually, categorized as:

Emissions along the value chain often represent a company’s biggest greenhouse gas impacts, often representing more than 90 percent of the company’s total emissions. Inclusion of Scope 3 emissions enables companies to understand their full value chain emissions and to focus their efforts on the greatest GHG reduction opportunities. Despite mandatory Scope 3 reporting for CPG companies in California not required until 2027 for the previous reporting year, early preparation and compliance offers a head start, a competitive edge, supply chain benefits, a smoother transition, and future-proofs them for stricter regulations.

This comprehensive set of disclosures, aligned with the Greenhouse Gas Protocol standards, will provide a clearer picture of a company’s environmental footprint. Independent verification adds a layer of credibility, ensuring the accuracy of reported data.

Climate Risks in Focus: Proactive Management

SB 261, the Climate-Related Financial Risk Act, complements SB 253 by requiring companies with revenue exceeding $500 million to disclose climate-related financial risks. This biennial report, starting in 2026, will delve into:

Following the Task Force on Climate-Related Financial Disclosure (TCFD) framework, this report empowers businesses to proactively manage climate risks and build resilience. Note that SB 261 lowers the revenue threshold ($500 million) compared to SB 253 ($1 billion) so it would cover an even larger set of companies.
