California’s climate disclosure rules target companies nationwide
Businesses incorporated in California and in the United States that have annual revenues of $1 bn or more and do business in California are required by California law to report their prior-year greenhouse gas emissions in 2026 and subsequent years.
Senate Bill 253 adopts the Greenhouse Gas Protocol as the reporting framework and requires verification by a third party.
OmnexFuturepast offers third-party verification services for this program. This webinar explains the differences between limited and reasonable assurance and how a consolidated organizational inventory of greenhouse gas emissions differs from facility-level greenhouse gas reporting. SB 261 requires U.S. businesses with $500 mn in annual revenue to publicly post climate-related financial risk disclosures by January 1, 2026, and biennially thereafter.
These disclosures can follow recommendations of the Task Force on Climate-related Financial Disclosures or similar reporting frameworks. The California Air Resources Board plans to finalize implementing regulations by the end of 2025.
