Our recent Client Alert provides a useful summary of the current state of play regarding the development of California’s corporate greenhouse gas reporting and climate-related financial risk disclosure programs (CA Climate Disclosure Laws). In late August, the California Air Resources Board, or CARB, held its second virtual public workshop as part of its regulatory development process, providing several key updates on definitional issues, annual fees, reporting deadlines, and reporting requirements, among others. In addition, on September 2, 2025, CARB released a checklist to help covered companies prepare for compliance with Senate Bill 261 (climate-related financial risk disclosures). We expect CARB to release additional guidance and information about the CA Climate Disclosure Laws, and we encourage all companies that believe they might be covered by the CA Climate Disclosure Laws to pay close attention to the CARB website for the latest information.
