Supreme Court Hears Climate Change Lawsuit Against Oil Companies
Confirmed
In Short: The Supreme Court heard arguments on Monday in a case that could set a precedent for climate change lawsuits against oil and gas companies.

Chief Justice John Roberts questioned the implications of allowing municipalities nationwide to file similar lawsuits, suggesting that if the court allows the case to proceed, “the next day... there will be at least 50” similar lawsuits filed in state courts around the country.
Attorney Kannon Shanmugam, representing the industry, argued that the Boulder case was attempting to use the courts to decide a public policy issue that is properly up to Congress and other elected officials.
Kevin Russell, an attorney representing Boulder, countered that state lawsuits can address damage in Colorado, regardless of where the fossil fuels are produced.
Justice Brett Kavanaugh said that “a wall of precedent” establishes that lawsuits concerning interstate air and water pollution are matters of federal law.
Justice Sonia Sotomayor pointed out that the high court has allowed similar suits to proceed in state courts.
Justice Ketanji Brown Jackson asked whether the case had reached the high court too early, noting that the Colorado Supreme Court has not decided other claims the companies have made in state court.
Sarah Harris, the principal deputy solicitor general, said Boulder’s case “egregiously exceeds” the state’s authority, arguing that interstate air pollution is an inherently federal area.
Boulder Mayor Aaron Brockett expressed optimism after the arguments, saying, “It's taken a long time to get to this point, but it feels very positive that that effort that we started in this exact location eight years ago has gotten to the stage of going to the Supreme Court, and then hopefully the next step of having a full hearing in court.”
What this adds
The case, Suncor Energy v., concerns whether Boulder County, Colorado, can sue two fossil fuel companies in state court to reclaim damages caused by climate change.
The Trump administration supports the companies, arguing the lawsuits are unconstitutional.
The court's decision could impact similar cases across the country.
Justice Samuel Alito recused himself from the case, leaving open the possibility that the Supreme Court deadlocks 4-4 in the case, which would mean the decision of the Colorado Supreme Court would stand, allowing Boulder's case to proceed.
