California climate disclosure laws: CARB delays SB 253 reporting deadline to November 10 - White & Case LLP
California's CARB has delayed the SB 253 reporting deadline to November 10, 2025, giving businesses more time to prepare climate disclosures.
Aforeworn detected this change in the ESG & Climate Disclosure space on July 6, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated Low urgency. Public companies and large private filers subject to SB 253 should confirm how it applies to their specific situation before acting. There is a time constraint attached: November 10, 2025. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors ESG & Climate Disclosure continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
