A federal judge has ruled New York's 2024 Climate Change Superfund Act unconstitutional, dealing what the report calls "a decisive blow" to superfund legislation. Chief Judge Brenda Sannes of the U.S. District Court for the Northern District of New York found that the law, signed by Governor Kathy Hochul, violated both the Supremacy Clause and the Clean Air Act. The ruling comes as other states weigh similar climate superfund proposals, prompting the report to frame the decision as a warning about the legal viability of such measures.

Judge Sannes outlined three core constitutional problems with the legislation. First, the Clean Air Act preempts New York's superfund law because federal environmental regulations already grant the U.S. Environmental Protection Agency authority to regulate greenhouse gas emissions at the interstate level, preventing New York from creating its own cap-and-trade emissions program. Second, the judge determined that climate change is inherently an international and interstate issue, giving the federal government exclusive power to craft a unified response that the state law would undermine. Third, the ruling emphasized that the federal government's foreign affairs authority applies because the law would affect companies beyond U.S. borders. An analysis by the New York Public Interest Research Group identified foreign firms including Saudi Aramco, BP, TotalEnergies, and Shell as entities that would fall under the Climate Change Superfund Act's reach, an area where New York lacks legal jurisdiction.

The decision spares New York consumers from potential cost increases, according to the report. Because of how superfund liability works, the expenses would ultimately fall on all taxpayers who benefited from fossil fuel use, translating into higher energy costs in a state that already has the fourth-highest electricity prices in the nation. The report notes these cost hikes aren't always immediate but can show up later. After Hurricane Sandy, New York created the FuelNY initiative to build a strategic fuel reserve for emergencies, but making it harder for fuel suppliers to operate in the state would complicate establishing this reserve. In an emergency, fuel prices would climb further as limited supply meets surging demand.

The ruling isn't necessarily final. Governor Hochul is reviewing next steps, potentially allowing New York Attorney General Letitia James to appeal. But the decision strengthens similar legal challenges, including the Trump Administration's lawsuit against Vermont over its own climate superfund law. For states weighing their own versions of climate superfund legislation, the report concludes the case demonstrates the legal fragility of such laws.
