The California Air Resources Board (CARB) has proposed extending the first greenhouse gas (GHG) emissions reporting deadline under California’s Climate Corporate Data Accountability Act (SB 253). The initial reporting deadline for Scope 1 and Scope 2 emissions has been moved from August 10, 2026, to November 10, 2026, providing organizations with an additional three months to prepare their disclosures while CARB finalizes the implementing regulations.
The extension follows CARB’s decision to withdraw its proposed regulations from review by the California Office of Administrative Law (OAL) to make targeted clarifications. Once revised, the regulations will be released for a 15-day public comment period before being resubmitted for final approval.
What Has Changed?
The proposed update includes several important changes:
• New reporting deadline: November 10, 2026 (previously August 10, 2026)
• Applies to: The inaugural reporting of Scope 1 and Scope 2 GHG emissions under SB 253
• Reason for the extension: CARB is refining the implementing regulations to provide additional clarity before final adoption.
• Next step: The revised regulations will undergo a 15-day public comment period before final approval.
What Remains the Same?
Although the reporting timeline has been extended, the underlying compliance requirements have not changed.
• Companies that fall within the scope of SB 253 are still expected to comply with the law.
• The first reporting cycle continues to focus on Scope 1 and Scope 2 emissions.
• Scope 3 emissions reporting is expected to begin in 2027, subject to CARB’s final regulations.
• Organizations should continue building robust emissions inventories, governance processes, and internal controls to ensure reporting readiness.
Regulatory Context
California’s climate disclosure framework continues to evolve, and organizations should distinguish between the state’s two major climate reporting laws.
SB 253, which requires eligible companies doing business in California to publicly disclose their greenhouse gas emissions, remains in effect following a federal appeals court decision allowing the law to proceed. In contrast, SB 261, California’s Climate-Related Financial Risk Act, is currently subject to ongoing litigation. A federal district court has temporarily paused enforcement of SB 261 while legal challenges continue, making compliance with its climate-related financial risk reporting requirements voluntary for now.
Organizations should continue monitoring legal and regulatory developments, as future court decisions and CARB’s finalized regulations may further shape California’s corporate climate disclosure landscape.
Why This Matters
While the revised deadline offers additional preparation time, organizations should not treat it as a delay in their compliance efforts.
Preparing high-quality emissions disclosures requires coordinated data collection, governance, validation, documentation, and review across multiple business functions. Companies that continue strengthening these processes now will be better positioned to meet California’s reporting requirements and other evolving global disclosure mandates.
For many organizations, California’s climate disclosure requirements form part of a broader sustainability reporting strategy that also includes frameworks and regulations such as the Corporate Sustainability Reporting Directive (CSRD), IFRS Sustainability Disclosure Standards, and other jurisdiction-specific reporting requirements. Building a centralized and governed reporting process can help reduce duplication while improving consistency across disclosures.
How EcoActive Helps
California’s evolving climate disclosure requirements highlight the importance of having a governed, audit-ready reporting process rather than relying on disconnected spreadsheets and manual workflows.
