Supreme Court to Hear Boulder Climate Lawsuit Against ExxonMobil and Suncor

The Case Before the Court
On September 30, the U.S. Supreme Court agreed to hear a lawsuit filed by the city and county of Boulder, Colorado, against ExxonMobil and Suncor Energy. The dispute centers on whether federal law precludes state-law claims that the companies misled the public about the risks of fossil fuels and caused climate-related harms. The arguments will be presented on the first day of the Court’s new nine-month term.
Legal Background
The litigation follows a series of pivotal rulings. In 2007 the Court held that greenhouse gases are air pollutants under the Clean Air Act, granting the EPA authority to regulate them. A 2011 decision blocked states and environmental groups from suing under federal law to force carbon-emission cuts, prompting plaintiffs to rely on state statutes. In 2021 the Court sided with energy firms on a procedural issue that allowed cases to be moved to federal court, a venue companies view as more favorable. The Boulder case reached the Supreme Court in 2023 after a lower-court ruling returned it to state court; Justice Samuel Alito recused himself from the current proceedings.
Positions of the Parties
Exxon and Suncor argue that federal law bars Boulder’s claims and that allowing the suit could let states regulate production nationwide. Boulder officials contend the companies misled the public while continuing to sell fossil fuels, seeking monetary damages for infrastructure repairs, environmental damage, emergency management and public-health harms.
Potential Impact
A ruling in favor of Exxon and Suncor could lead to the dismissal of dozens of climate-related suits filed by state and local governments, limiting the ability of jurisdictions to hold fossil-fuel producers accountable for greenhouse-gas emissions. Conversely, a decision upholding Boulder’s claims could expand the reach of state-law climate litigation, potentially affecting thousands of other companies.
