California sets 2026 climate disclosure deadline

SACRAMENTO - California’s Air Resources Board (CARB) has formally adopted an initial climate‑transparency regulation to implement SB 253 and SB 261, setting fees, key definitions and the first binding deadline for corporate emissions reporting.

The new rule – 'California Greenhouse Gas Reporting and Climate Financial Risk Disclosure Initial Regulation' – was approved at CARB’s February meeting as the first implementing step for SB 253 (Climate Corporate Data Accountability Act) and SB 261 (Climate‑Related Financial Risk Act).
