Federal Court Voids New York's Climate Superfund Act
A district court ruled the state's $75 billion 'polluter pays' law is preempted by federal law and improperly regulates extraterritorial conduct.
On August 31, 2026, the US District Court for the Northern District of New York invalidated the state's Climate Change Superfund Act, a 'polluter pays' law that sought to create a US$75 billion cost-recovery program. The Act would have imposed liability on certain fossil fuel producers for climate adaptation projects based on their worldwide greenhouse gas emissions between 2000 and 2024. The court granted summary judgment for a coalition of states and industry groups, finding the state law was preempted by the federal Clean Air Act. Citing the Second Circuit's decision in City of New York v. Chevron, the court found no material distinction between the Act's statutory scheme and preempted tort claims. The ruling also found the Act’s reliance on extraterritorial emissions raised significant foreign policy concerns, providing an independent basis for invalidation. This decision offers a detailed roadmap for future preemption challenges to similar state-level climate liability laws and will be a focal point in litigation nationwide as New York is expected to appeal.
