Supreme Court Hears Climate Case Against Oil Giants

The U.S. Supreme Court opened its new term Monday hearing arguments in Suncor Energy v. Boulder County, a case that could determine the fate of dozens of climate lawsuits nationwide. Boulder, Colorado, sued Suncor and ExxonMobil in 2018, alleging the companies deceived the public about fossil fuels' role in climate change and seeking damages for resulting disasters like the 2021 Marshall Fire.

The oil companies argue that the Clean Air Act and the Constitution reserve climate policy for the federal government, warning that allowing state suits would let thousands of local juries set national energy policy. Colorado courts ruled the case can proceed under state nuisance and consumer protection laws, rejecting federal preemption arguments.

“We lost our homes and they left us to figure out for ourselves how to make our neighborhoods safe again. At the end of the day, it comes out of our pockets.”

Justice Samuel Alito recused himself days before the hearing due to financial holdings in the energy sector, raising the possibility of a 4-4 deadlock that would leave the Colorado ruling intact. Chief Justice John Roberts and Justice Neil Gorsuch expressed skepticism about the industry's preemption claims but also concern about the lawsuits' sweeping reach.

A ruling is expected by July. The outcome will shape whether states and municipalities can use tort law to recover climate adaptation costs from fossil fuel producers.
