On March 23, 2026, the California Air Resources Board (CARB) held a public workshop initiating the next phase of rulemaking under SB 253, California’s Climate Corporate Data Accountability Act. CARB presented preliminary, pre‑rulemaking concepts that would govern greenhouse gas (GHG) emissions reporting beginning in 2027. Because the first reporting year would cover 2026 emissions, potentially regulated entities should consider evaluating these concepts now and may wish to submit comments to CARB’s rulemaking docket before April 13, 2026.
