Supreme Court opens its term with Boulder’s climate lawsuit against Exxon and Suncor
On the first argument day of the new term, eight justices — Samuel Alito has stepped aside — hear oil companies’ bid to throw out a Colorado lawsuit seeking damages for local climate-change costs.
The case: The Supreme Court’s new nine-month term begins Monday with arguments in Suncor Energy Inc. v. County Commissioners of Boulder County, NBC News and NPR reported. Boulder, Colorado, sued Exxon Mobil and Suncor Energy in 2018 under state law, alleging the companies misled consumers about the climate effects of fossil fuels. Boulder says it wants to recover past and future costs of repairs, emergency services and property damage, including wildfire-risk work, NPR said. The case has not gone to trial; it is still in early stages in Colorado courts.
The companies’ argument: Exxon and Suncor deny the allegations. They argue that climate change is an inherently national and international issue that only the federal government can address, and that the federal Clean Air Act overrides such state-law claims, NBC News reported. The Trump administration filed a brief backing the companies.
Boulder’s answer: Boulder’s lawyers say state courts have long handled cases with nationwide effects, such as product liability, and that the suit does not seek to cap any emissions — it is about alleged consumer deception, NBC News reported.
Alito steps aside: The court told lawyers about a week before argument that Justice Samuel Alito would not participate, without giving a reason, NPR reported. Watchdog groups had urged recusal over his investments in oil companies. With eight justices, a 4-4 tie would leave in place the Colorado Supreme Court’s decision allowing the lawsuit to proceed, NPR and NBC News said. The justices are also considering whether they have jurisdiction to hear the case at this early stage.
Why it reaches beyond climate: NBC News said the ruling could affect more than two dozen similar suits nationwide. Lawyer Deepak Gupta said at a Georgetown briefing that the question of state power also touches forever-chemical pollution, nuisance suits over AI data centers and opioid litigation, NPR reported. Other major cases on the term’s docket include a challenge to AR-15 bans and two cases on the Trump administration’s immigration policies, NBC News said.
What this means: This is a fight over who gets to decide — state courts or Washington — when a local government says a national industry harmed it. A ruling for the companies could close the door on dozens of similar cases; a tie or a jurisdiction dismissal would send Boulder’s suit back to Colorado for now.
