In a federal courtroom in Rutland, Vermont, on Monday, state attorneys mounted a vigorous defense of the nation's first climate superfund law, arguing that it falls squarely within the state's traditional authority to protect its citizens and environment. The law, enacted in 2024, seeks to hold fossil fuel companies accountable for damages linked to climate change, drawing inspiration from the federal superfund program that taxes polluters to clean up toxic waste sites. Vermont's push comes in the wake of devastating summer flooding in 2023 and other extreme weather events, which scientists attribute to the increasing frequency of climate-driven disasters.
The courtroom battle pits Vermont against powerful opponents, including the U.S. Chamber of Commerce, the American Petroleum Institute, and the Trump administration's Department of Justice. The Chamber and API filed suit in December 2024, claiming the law is unconstitutional and violates federal regulations by imposing liability on out-of-state energy producers for global greenhouse gas emissions. Adding to the fray, Attorney General Pam Bondi, acting on President Donald Trump's orders, sued Vermont and New York over their similar measures, describing them as "burdensome and ideologically motivated" threats to American energy independence and national security.
Vermont's legal team urged U.S. District Judge Mary Kay Lanthier to dismiss both lawsuits, emphasizing that the state has the sovereign right to raise revenue and address environmental harms without interfering in federal energy policy. "As a sovereign state, Vermont gets to do certain things that are exercises of a traditional state authority. The Superfund Act operates squarely in those areas of traditional state authority," said Jonathan Rose, an attorney with the Vermont attorney general’s office, during the hearing.
The proposed superfund would collect funds from fossil fuel companies to finance climate adaptation projects, including upgrades to stormwater drainage systems, sewage treatment plants, and roads battered by intensifying storms. Proponents argue this mirrors the 1980 federal Superfund law, which has successfully held polluters accountable for environmental cleanup. Vermont officials maintain the law neither regulates emissions nor punishes producers but simply seeks compensation for in-state damages.
Opponents, however, contend that the law overreaches by attempting to regulate global energy production under state jurisdiction. "This case is not about Vermont’s ability to raise revenue and protect the health and welfare of its residents. It’s about Vermont’s attempt to subject global energy production activity to Vermont law, which brazenly disregards the constitutional division of power in the federal government and the states," argued Riley Walters, a Department of Justice attorney, in court.
Walters highlighted the challenges in linking specific emissions to Vermont's harms, noting that greenhouse gases mix globally and make traceability "impossible." He pointed out that previous court rulings allowing state laws to apply to out-of-state conduct required direct connections, which he said are absent here. "It’s impossible to trace in-state harm to any particular source of greenhouse gas emissions, let alone to the fossil fuel production that is even further down along the alleged causal chain," Walters said. "There is not a direct and traceable connection between oil that’s extracted in Texas or in Saudi Arabia and a flood or some other weather event that takes place in Vermont."
West Virginia, a major producer of natural gas and coal, is leading a coalition of two dozen states intervening on the side of the Chamber and API. These states fear the law could lead to demands for billions in recoveries from energy firms within their borders, potentially disrupting local economies. On the opposing side, the Conservation Law Foundation, a New England environmental advocacy group, and the Northeast Organic Farming Association of Vermont have filed briefs supporting the state, warning that striking down the law could embolden federal overreach into state affairs.
Adeline Rolnick, representing the conservation foundation and farmers' association, told Judge Lanthier that allowing the plaintiffs' motions would grant the federal government a "roving license to seek to enjoin any state law that it disagrees with simply by pleading preemption." She argued, "That would be quite an expansion of the federal role in our state-federal system, and the court should instead require the United States to show concrete imminent injury like any other litigant." Rolnick's comments underscored concerns about the balance of power in the U.S. federal system.
Judge Lanthier took the motions under advisement and indicated she would issue rulings as soon as possible, leaving the fate of Vermont's pioneering legislation hanging in the balance. The hearing drew attention not just for its legal stakes but as a flashpoint in the broader national debate over climate accountability. Vermont Republican Gov. Phil Scott allowed the bill to become law without his signature in 2024, expressing reservations about the state confronting the oil industry single-handedly but acknowledging the need for action after years of severe weather impacts.
Since Vermont's move, the concept has spread. New York Gov. Kathy Hochul, a Democrat, signed a similar law last year, prompting the DOJ's lawsuit. Other Democratic-led states are weighing comparable measures, while some are pursuing damages from fossil fuel companies through state courts for climate-related harms. "This is the first time that a state legislature has taken the gigantic step of pursuing polluters and holding them accountable to clean up the mess that they’ve made," said Jennifer Rushlow, interim vice president for CLF Vermont, highlighting the law's potential as a model for nationwide change.
The economic arguments on both sides are stark. The U.S. Chamber of Commerce, through its Global Energy Institute, warned that the law could impose "massive retroactive penalties" on energy producers, with disastrous effects on American families. Marty Durbin, president of the institute, stated, "Reliable, affordable energy helps power economic growth and enhances the quality of life for American families and communities. It defies logic that Vermont would pursue gigantic penalties from companies who are meeting consumer and business demand for this essential resource."
Environmental advocates counter with data on the scale of climate damages. A Dartmouth College research team estimated last year that the world’s largest corporations have inflicted $28 trillion in climate-related harm, with more than half of that figure tied to just 10 fossil fuel providers among 111 companies studied. The researchers' findings, published in a peer-reviewed study, underscore the global scope of the issue and bolster arguments for holding major emitters financially responsible.
Vermont's 2023 flooding alone caused billions in damages, destroying homes, businesses, and infrastructure across the state. Officials reported widespread inundation in areas like Montpelier and Barre, where rivers overflowed and washed away roads and bridges. Such events, linked by scientists to warmer atmospheric conditions from greenhouse gases, have prompted states like Vermont to seek innovative funding for resilience projects amid federal inaction on broader climate policy.
As the case progresses, it could set precedents for how states address climate change in an era of divided national politics. The Trump administration's lawsuit reflects a pushback against state-level environmental regulations, aligning with its emphasis on fossil fuel expansion. Meanwhile, supporters see Vermont's law as a necessary step toward justice for communities bearing the brunt of a crisis they did not create.
With rulings pending from Judge Lanthier, stakeholders on all sides await clarity. The outcome may influence not only Vermont and New York but also the trajectory of similar initiatives in states from California to Minnesota. For now, the courtroom in Rutland stands as a microcosm of the tensions between local environmental imperatives and national energy interests.
