On February 23, 2026, the U.S. Supreme Court granted the petition for writ of certiorari in Suncor Energy, Inc. v. County Commissioners of Boulder County (No. 25-170). In addition to addressing the question presented by petitioners regarding federal preemption of state-law climate change claims, the Court has also directed the parties to brief and argue whether the Court has statutory and Article III jurisdiction to hear the case. This case will be closely watched to determine its impact on underlying climate change litigation in the U.S.

QUESTION PRESENTED Whether federal law precludes state-law claims seeking relief for injuries allegedly caused by the effects of interstate and international greenhouse-gas emissions on the global climate.

A federal district court has preliminarily enjoined the EPA from reclassifying California's Clean Air Act preemption waiver orders as "rules" subject to the Congressional Review Act. The court found that EPA's reclassification likely violated the Administrative Procedure Act and exceeded the agency's authority, though the order does not prevent Congress from proceeding with pending disapproval resolutions.

EPA Issues Decisions On Small Refinery Exemptions

The EPA has released decisions on 34 small refinery exemption petitions from 2025, granting full or partial exemptions that total 1.76 million RINs - significantly more than initially estimated. This discrepancy has prompted the agency to announce a new rulemaking that will reallocate 100 percent of exempted volumes to 2026 and 2027 renewable volume obligations, potentially increasing compliance burdens for nonexempt obligated parties.

Commission Proposes EU Public Procurement Act

The European Commission has proposed replacing the EU's three core procurement directives with a single, directly applicable Regulation that would fundamentally reshape how companies compete for public contracts across Member States.
