The Supreme Court opens its term with Suncor Energy v. Boulder County, the first of dozens of climate-accountability lawsuits to reach the justices, with oil companies arguing that federal law and the Constitution preempt local tort claims over climate damage.
Boulder sued Suncor and Exxon in 2018 for costs tied to heat waves, drought, and flooding, accusing the companies of misleading the public about fossil fuels' role in warming. The companies now invoke the same Clean Air Act authority the Trump administration has spent the year rolling back, including rescinding the 2009 endangerment finding that underpinned greenhouse gas regulation.
Justice Alito recused without explanation, leaving eight justices on a court that has already curtailed EPA authority once in West Virginia v. EPA. Advocates say the case is less about jurisdiction than about closing the last open door, after legislation and regulation, for anyone seeking to make fossil fuel companies pay.
