The California Air Resources Board (CARB) will hold a virtual public workshop to support the development of the California Corporate Greenhouse Gas Reporting Program authorized by Senate Bill (SB) 253 (Wiener, Stats. 2023; codified in Health & Safety Code (HSC) § 38532), as amended by SB 219 (Wiener, Stats. 2024, Chapter 766; codified in HSC §§ 38532 and 38533).
The workshop will include an update from CARB staff on additional information for the August 10, 2026, Scope 1 and Scope 2 emissions reporting deadline. The workshop will also cover the next stage in regulatory development and provide an overview of the development of the greenhouse gas reporting requirements for 2027-2030 under HSC § 38532. Discussion will include preliminary staff options for Scope 3 emissions reporting requirements for 2027-2030, a solicitation of alternative approaches, and an overview of staff’s approach to the economic analysis.
The workshop will be held virtually:

Time: 1:00 p.m. – 4:00 p.m. (Pacific Time)

Status of Initial Fee Regulation
On February 26, 2026, the Board approved a regulation to establish a fee component and set the first reporting deadline under HSC § 38532. Reporting entities are required to report Scope 1 and Scope 2 GHG emissions by August 10, 2026, as described in the Enforcement Notice published by CARB in December 2024. Under this initial regulation, entities subject to HSC § 38532 would be required to report Scope 1 and Scope 2 emissions by the proposed deadline.
Background
The California Corporate Greenhouse Gas Reporting Program, authorized by Senate Bill (SB) 253 (Wiener, 2023, codified in Health & Safety Code § 38532), is being developed by CARB and will require U.S.-based companies, with total annual revenues in excess of one billion dollars ($1,000,000,000) that do business in California (“reporting entities”) to annually disclose their Scope 1, Scope 2 and Scope 3 emissions for the prior fiscal year. The initial (first-year) annual emissions disclosures in 2026 are required to address Scope 1 and Scope 2 emissions, and in subsequent years (beginning in 2027) must include Scope 3 emissions.
