Vermont’s Climate Superfund Law Faces Legal Challenges

Vermont’s pioneering move to hold fossil fuel companies financially responsible for climate change impacts is currently under scrutiny in a federal courtroom. The state is defending its 2024 law against two lawsuits, arguing for their dismissal.

In a first-of-its-kind initiative, Vermont established a climate superfund law, inspired by the federal superfund law, which previously taxed petroleum and chemical companies to address toxic waste pollution. This legislation follows the severe summer flooding of 2023 and other extreme weather events, which scientists attribute to the increasing effects of climate change. The funds collected are earmarked for climate adaptation projects, including improvements to stormwater systems, sewage plants, and infrastructure.

The U.S. Chamber of Commerce and the American Petroleum Institute have filed lawsuits against Vermont, labeling the law as unconstitutional and in conflict with federal regulations. The U.S. Department of Justice also brought a case against Vermont, referencing an order by President Donald Trump for Attorney General Pam Bondi to counteract what he views as state overreach in energy regulation. Bondi criticized Vermont’s law, alongside a similar one in New York, as “burdensome and ideologically motivated,” claiming they threaten energy independence and national security.

State’s Defense of Its Legislative Authority

Vermont argues that its law aligns with the state’s right to generate revenue, safeguard public health, and address environmental issues. The state asserts that the law neither conflicts with federal mandates nor regulates fossil fuel emissions. “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,” stated Jonathan Rose from the Vermont attorney general’s office during the court proceedings in Rutland.

Conversely, the plaintiffs argue that Vermont cannot impose penalties on out-of-state energy producers for global greenhouse gas emissions. DOJ attorney Riley Walters emphasized, “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.”

Interstate Opposition and Support

West Virginia, a significant producer of natural gas and coal, is spearheading opposition among two dozen states concerned about Vermont’s potential financial demands on energy producers. Meanwhile, Vermont’s law has garnered support from the Conservation Law Foundation and the Northeast Organic Farming Association of Vermont. Attorney Adeline Rolnick, representing these groups, argued that invalidating the law would unnecessarily expand federal authority over state legislation.

Judge Mary Kay Lanthier is currently reviewing the motions and will issue decisions promptly. The U.S. Chamber of Commerce anticipates a favorable ruling, with Marty Durbin of the Global Energy Institute stating that Vermont’s penalties could be detrimental to American families and economic growth.

Despite concerns, Republican Gov. Phil Scott allowed the law to pass without his signature. The concept has since gained traction in other Democratic-led states, with some pursuing similar legislative measures or seeking damages from fossil fuel companies for climate-related harms. Jennifer Rushlow of CLF Vermont remarked, “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.”

A Dartmouth College study estimated $28 trillion in climate damage caused by major corporations, with a significant portion attributed to 10 fossil fuel companies.
