Supreme Court Case Could Reshape Local Climate Lawsuits
The Supreme Court is weighing Suncor v. Boulder County, a case in which Colorado local governments sued oil companies over climate change damages and allegedly deceptive marketing. The companies contend that federal law or the Constitution preempts the claims, while the governments argue they are only seeking compensation for harm. The justices' eventual ruling could influence other climate lawsuits and broader questions about when state and local governments may sue.
The dispute began in 2018, when Boulder’s city and county governments and San Miguel County sued Suncor and Exxon. They seek money to help cover climate-related costs and allege the companies misled consumers about their products’ dangers. Colorado’s top court allowed the case to proceed in 2025. The companies argue federal law or the Constitution bars the claims; the Trump administration backs them. The justices heard arguments in early October and may decide by June or July.
Other climate cases, including in California and New Jersey, are paused awaiting the outcome. State courts have disagreed on similar preemption questions, with Minnesota and Maryland reaching different conclusions this year. Local governments have also used comparable theories in suits over PFAS, opioids, and ghost guns, while the White House warns of interstate and global interference.

... No extra. Need maybe "EXPANDED:" and "CONTEXT:" labels. Good. Potential issue: EXPANDED says "State courts split this year: Minnesota and Maryland reached opposite results on preemption." Source says state courts themselves split over whether federal law pre-empts states and governments from bringing similar deception cases against fossil fuel companies, with Minnesota and Maryland landing on opposite sides this year. Our phrasing okay. "Municipalities have used comparable claims over PFAS, opioids, and ghost guns." Source: anti-gun violence groups say cities used similar legal theories to Boulder's to fight ghost gun dealers. Local governments sued over PFAS and opioids. Good.
