On Monday, June 9, the U.S. Fish and Wildlife Service (FWS) opened a short, 30-day public comment period soliciting information and comments to, “improve the overall efficiency and effectiveness” of Section 10(a) take permitting under the Endangered Species Act (ESA). If it seems like Section 10(a) just underwent a comment period not too long ago, that’s because it did. In 2023, under the Biden Administration, FWS solicited comments on proposed revisions to the regulations implementing that section, which were finalized last April. Now, the Trump Administration is seeking suggestions on how to further revise its ESA permitting rules.
CARB Workshop on Climate Disclosure Laws: More Questions Than Answers
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.
Citizen Suits and Larger Penalties May Be the Future of California Water Quality Protections
The California legislature continues to advance Senate Bill 601 (SB 601), the “Right to Clean Water Act,”[1] which aims to safeguard protections for California’s streams and wetlands that lost federal protection under the Clean Water Act (CWA) as a result of the Supreme Court’s 2023 Sackett v. U.S. EPA decision. If approved, SB 601 would expand enforcement to include citizen suits and increase penalties for unpermitted discharges to state waters.
No Harm, No Foul? Services Propose to Remove Harm Definition from Endangered Species Act Regulations
On April 17, the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) (together Services) published a proposed rule to rescind the long-standing definition of “harm” under the Endangered Species Act (ESA). The proposal appears to be one of the first in response to President Trump’s April 9 Presidential Memorandum, “Directing the Repeal of Unlawful Regulations,” which directs federal agencies to revise or rescind regulations that conflict with the plain meaning of the underlying statute. If adopted, it will significantly change the ESA’s implementation. The FWS and NMFS are taking comments on the proposed rule from April 17 through May 17.
New Executive Order Challenges State Climate Laws
Challenging a slew of state climate-related laws and programs, President Trump’s April 8, 2025 executive order (EO) set the stage for more legal fights between the federal government and states. In the new EO, “Protecting American Energy from State Overreach,” Trump took aim at state laws and programs that address greenhouse gas emissions (GHGs), climate change, environmental justice, and environmental, social, and governance (ESG). Some states have already indicated they will oppose the Trump administration’s efforts.
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.
Court Order Hobbles Challenge to California’s Climate Disclosure Laws
Companies following the ongoing legal challenge to California’s climate disclosure laws in hopes that the court would strike down or limit the scope of these laws will be disappointed by the order issued by the U.S. District Court for the Central District of California on February 3, 2025. The order dismissed constitutional challenges levied against SB 253, which requires large companies “doing business” in California to annually report their greenhouse gas (GHG) emissions, and SB 261, which requires disclosure of climate-related financial risks. The ruling clears the path for the California Air Resources Board (CARB) to develop implementing regulations for SB 253, which are statutorily required to be issued by July 1, 2025.
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
On December 5, 2024, the California Air Resources Board (CARB) issued an Enforcement Notice regarding the Climate Corporate Data Accountability Act (SB 253), which will require companies “doing business” in California to report their Scope 1, 2, and 3 greenhouse gas emissions (GHG), with reporting for 2025 Scope 1 and 2 emissions beginning in 2026 (see our previous discussion of the law’s requirements here).
