Under the program, companies deemed responsible for more than 1 billion tons of greenhouse gas emissions during that period could have been ordered to contribute to a massive state-controlled fund.
Beginning in 2028, the targeted companies were expected to collectively pay approximately $3 billion every year.
Over 25 years, New York planned to collect a staggering $75 billion.
The financial burden would have been divided among companies according to the percentage of qualifying emissions the state attributed to each business.
New York officials intended to use the money for infrastructure projects they argued were necessary to prepare for the consequences of climate change.
That included spending on roads, sewer and water systems, public transportation, stormwater infrastructure, electrical systems, coastal defenses and programs intended to reduce the dangers associated with extreme heat.
But U.S. District Judge Brenda Sannes concluded that New York had ventured into territory governed by federal law.
At the center of the dispute was the federal Clean Air Act, which gives the Environmental Protection Agency authority over greenhouse gas emissions.
Sannes determined that the federal framework did not give individual states free rein to establish the kind of emissions-based compensation system created by Albany.
Her ruling described climate policy as an issue extending far beyond New York’s borders.
“The Climate Act is an unusual and sweeping statute, designed to address the effects of climate change–a ‘uniquely international problem of national concern,’” Sannes wrote. “Thus, the Court finds the Climate Act is ‘simply beyond the limits of state law.’”
The judge went even further in explaining why New York could not enforce the program.
“It is precisely because the Climate Act operates within an area of law in which the federal interest is so dominant that it cannot be enforced.”
That conclusion strikes directly at the legal foundation of one of New York Democrats’ most aggressive climate initiatives.
The court also found problems with New York attempting to impose financial responsibility on foreign fossil fuel producers.
Sannes concluded those provisions were preempted under the foreign affairs doctrine, further limiting the state’s ability to pursue companies for worldwide economic activity.
The ruling drew partly from the Second Circuit’s 2021 decision in City of New York v. Chevron Corp., another major legal battle over attempts to make energy companies financially responsible for alleged climate-related damages.
This latest fight began in February 2025 when a coalition of 22 states, led by West Virginia, challenged New York’s law.
Several major industry organizations joined the legal battle, including the U.S. Chamber of Commerce, American Petroleum Institute and National Mining Association.
The U.S. Department of Justice subsequently backed the challengers.
New York officials have indicated they are now considering their options following the federal court defeat.
The setback comes less than two years after Democratic Gov. Kathy Hochul signed the legislation into law on December 26, 2024.
The measure had previously cleared the Democrat-controlled New York Senate in May 2024 and the Assembly the following month.
Supporters promoted the program using the familiar “polluter pays” argument, comparing it to the federal Superfund system used to address contaminated hazardous-waste sites.
But New York’s approach went considerably further by imposing strict financial liability based on historical fossil fuel activity.
The targeted companies did not have to be accused of violating environmental laws when they extracted, refined or sold the fuels in question.
Instead, liability was calculated according to emissions associated with their products over the law’s designated historical period.
That meant companies could face enormous bills today for lawful business conducted years earlier.
New York’s Department of Environmental Conservation was charged with determining which businesses qualified as responsible parties, calculating their individual financial obligations and collecting the resulting payments.
The agency would then oversee how the billions were directed toward approved climate adaptation projects.
Part of the money was specifically earmarked for communities classified by the state as “disadvantaged communities.”
For Hochul and New York Democrats, the law represented an effort to transfer a substantial portion of the cost of their climate adaptation agenda from taxpayers to the fossil fuel industry.
For opponents, however, the program represented an extraordinary attempt by a single state to impose retroactive financial penalties on companies over emissions connected to a global marketplace.
The federal court has now sided with the challengers on the central legal question.
New York may consider an appeal, meaning the battle might not be finished.
But unless the ruling is overturned, Albany’s plan to collect $75 billion from fossil fuel producers has hit a formidable legal roadblock — and other states considering similar climate liability schemes now have another federal court decision to contend with.
