A federal judge in the Northern District of New York has struck down New York’s Climate Change Superfund Act, ruling that the “polluter pays” climate law is preempted by federal law and “simply beyond the limits of state law.” The court concluded that the Clean Air Act (CAA) does not authorize New York’s compensation scheme, which calculates liability based on greenhouse gas (GHG) emissions attributable to worldwide fossil fuel extraction and refining. It separately held that any cost-recovery demand against a foreign producer would be preempted under the constitutional foreign affairs doctrine, which limits state intrusion into matters committed predominantly to the federal government. The court directed the parties to file a status report by September 14, leaving the form of further relief unresolved. In practical terms, the court has decided that the Act is preempted and cannot be enforced but has not yet determined the precise terms of its final order, including whether to formally enjoin its enforcement.

The decision in West Virginia v. James, Case No. 1:25-cv-00168 (N.D.N.Y. Aug. 31, 2026), issued by Chief U.S. District Judge Brenda K. Sannes, who was appointed by President Obama, marks the first judicial invalidation of a state climate superfund statute and carries significant implications for the climate superfund landscape and the three remaining lawsuits challenging these laws.
