California Air Resources Board

Thursday, August 21, 2025

9:30 AM - 12:30 PM

The California Air Resources Board will hold a virtual public workshop where staff will present a draft framework for a fee regulation, as authorized by Health and Safety Code § 38532 and 38533. The workshop will also draft definitions needed for determining covered entities, such as “revenue”, “doing business in California”, and “parent-subsidiary” relationships. These definitions are relevant to implementing the statutes, which require first reports due in 2026, as they will inform which companies will be subject to reporting. Staff will also provide updates on the regulatory development timeline, considerations for assurance requirements under the California Corporate Greenhouse Gas Reporting Program, take input on proposed minimum reporting requirements related to Health & Safety Code § 38533, and discuss phasing in details for Scope 3 emissions in relation to the largest sectors of emissions.  Staff will take verbal feedback during the workshop and will open a public docket for written comments to remain open for three weeks following the workshop.

The California Air Resources Board held a virtual public workshop to support the development of California’s Corporate Greenhouse Gas Reporting Program, established by Senate Bill (SB) 253 (Wiener, 2023), and the Climate-Related Financial Risk Disclosure Program, authorized by SB 261 (Stern, 2023). SB 219 (Wiener, 2024) amended both programs, extending certain deadlines and implementing other administrative changes. The workshop included an overview of the above-mentioned legislation, a timeline for regulatory development, and an overview of feedback received from stakeholders from our December 2024 California Climate-Disclosure Information Solicitation. Additional presentations will include a comparative analysis of greenhouse gas accounting and reporting mechanisms that currently exist across various regulatory and voluntary programs.
