On May 29, 2025, the California Air Resources Board (CARB) held a virtual public workshop to review and discuss its rulemaking response to California Senate Bills (SBs) 253, 261, and 219, which require companies that “do business in California” and meet certain revenue thresholds to publicly disclose their greenhouse gas (GHG) emissions and material climate-related financial risks. Although CARB staff presented some “initial staff concepts” concerning CARB’s approach to implementing SBs 253 and 261, CARB asked more questions than it provided answers. The clear takeaway from the workshop was that CARB has a long way to go before it is ready to issue a formal notice of proposed rulemaking on SBs 253 or 261, and there is still an open question of whether CARB will issue guidance or regulations for SB 261, which is self-implementing.
California’s AB 550: A Blueprint for Balancing Development and Species Conservation
California’s drive toward a net-zero carbon economy by 2045 is sparking innovative solutions to harmonize environmental conservation with infrastructure development. Assembly Bill (AB) 550, sponsored by Assembly Member Petrie-Norris, aims to amend the California Endangered Species Act (CESA) by permitting renewable energy projects to take unlisted but “at-risk” species. The proposed legislation recognizes the dual imperative of advancing clean energy while conserving California’s biodiversity.
California Sets Stage to Improve Hazardous Waste Management
In what should be welcome news to industry and others who generate hazardous waste in California (including contaminated soil), the California Environmental Protection Agency (CalEPA), through the Department of Toxic Substances Control (DTSC), released a Draft Hazardous Waste Management Plan: A Modern Approach to a Circular Economy (Plan) on March 15. As provided in the Plan, DTSC proposes to potentially simplify the characterization of hazardous waste, provide for alternative management standards for certain hazardous wastes, and adopt certain existing U.S. EPA recycling exemptions and exclusions.
CARB Solicits Public Input on Greenhouse Gas and Climate Risk Disclosure Laws
On December 16, 2024, the California Air Resources Board (CARB) requested public feedback to “help inform its work to implement” the Climate Corporate Data Accountability Act (SB 253) and the Climate-Related Financial Risk Act (SB 261) (see our summary of these 2023 laws here). The “information solicitation” was issued shortly after California State Senator Scott Wiener and Senator Henry Stern, who authored the bills, penned a letter to CARB expressing their frustration with CARB’s apparent lack of momentum in advance of a July 2025 statutory deadline to adopt regulations governing the greenhouse gas (GHG) and climate risk disclosures that large entities “doing business in California” must make beginning in 2026. CARB is accepting comments in response to the solicitation for 60 days, through February 14, 2025.
California Offers Enforcement Relief on GHG Disclosures

California Adopts Landmark GHG Emissions and Climate Risk Reporting Laws
On October 7, 2023, California Governor Newsom signed two landmark bills into law, Senate Bill (SB) 253 and SB-261, imposing new requirements on large companies doing business in California to publicly report their annual greenhouse gas (GHG) emissions and climate-related risks. These laws apply to both publicly traded and privately held companies, exceeding the scope of the climate disclosure rule proposed by the U.S. Securities and Exchange Commission (SEC) in March 2022.
