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.

On May 29, the Supreme Court issued a unanimous opinion in Seven County Infrastructure Coalition v. Eagle County, Colorado that dramatically changes the way courts scrutinize federal agencies’ environmental reviews under the National Environmental Policy Act (NEPA). Justice Brett Kavanaugh, writing for a five-justice conservative majority (with Justice Neil Gorsuch abstaining), held that (a) courts must afford federal agencies “substantial judicial deference” regarding both the scope and contents of their environmental analyses; and (b) courts do not need to consider the effects of the action to the extent they are “separate in time or place” from the proposed project. The ruling gives federal agencies permission to greatly streamline their NEPA analyses at a time when those agencies are rapidly being drained of their resources and facing increasing pressure to expedite lengthy permitting processes.

In an 8-0 decision, the U.S. Supreme Court reversed a D.C. Circuit ruling that had blocked construction of a new 88-mile freight railroad line, clarifying the scope of impacts that federal agencies must consider under the National Environmental Policy Act (NEPA).

It seems that the death of Chevron deference was not the end of agency deference.
