Supreme Court weighs state climate suits against oil majors

The Supreme Court heard arguments in Suncor v. Boulder, a case determining whether federal law prevents municipalities from suing fossil fuel companies under state tort law for alleged climate damages. The dispute centers on whether states like Colorado can hold oil producers accountable for emissions that cross state and national borders, or if such matters fall exclusively under federal jurisdiction.

The city and county of Boulder, Colo., filed the lawsuit against ExxonMobil and Suncor Energy in 2018. The municipalities accuse the companies of knowingly contributing to climate change while misleading the public about the dangers of fossil fuels. Boulder seeks damages to cover costs associated with climate-related harms, citing a 1977 internal ExxonMobil memo that reported scientific opinion favored the link between fossil fuels and rising CO2 emissions. The company argues that because greenhouse gases travel globally, state law cannot impose liability for emissions originating outside its borders.

Energy policy experts warn that a ruling allowing such suits could have severe economic consequences. Jason Isaac, CEO of American Energy Institute, told Fox News Digital that a decision in Boulder's favor would trigger a "mass exodus" from the industry, creating fuel scarcity and driving up prices. Isaac stated that over 90,000 government entities in the United States could initiate similar lawsuits, leading to astronomical defense costs that would ultimately be passed to consumers. He described the potential outcome as opening "Pandora's box" for the energy sector.

During oral arguments, Justice Brett Kavanaugh raised concerns about the financial scale of potential litigation, warning that enough lawsuits could "bankrupt" defendants. He questioned whether the legal theory could extend beyond oil producers to other manufacturers. Justice Clarence Thomas pressed Boulder's attorney, Kevin Russell, on whether the theory exposes businesses beyond the oil industry, including large retailers. Russell acknowledged that nothing in their theory prevents such expansion, though he noted state tort law might impose additional limitations.

O.H. Skinner, executive director of the Alliance for Consumers, argued that these lawsuits aim to implement a backdoor carbon tax because Congress has not passed such legislation. Skinner suggested that liability could extend across the energy supply chain to automakers, utilities, and gas stations. Former Boulder counsel David Bookbinder, who is no longer involved in the case, previously characterized the suit as an "indirect carbon tax" at a Federalist Society forum last year. Boulder maintains that the case is not an attempt to regulate national climate policy but rather an exercise of state authority to provide tort remedies for injuries occurring within its borders.

Utah Attorney General Derek Brown told Fox News Digital that if Colorado wins, it would drive up gas prices nationwide. Brown argued that such decisions are the province of Congress, noting that other states like Utah have already barred these types of state tort lawsuits. Justice Samuel Alito has recused himself from the case without providing an explanation.
