Climate Litigation Claims

ExxonMobil Holdings Corp · 2026-10-01 · Importance 34 · Surprise 42

Exxon Mobil and Suncor Energy petitioned the U.S. Supreme Court to dismiss a climate-change lawsuit brought by the city and county of Boulder. The companies argue that climate change is a global issue outside the scope of state-level litigation and that the federal Clean Air Act should govern the claims. The Justice Department supports the companies, while environmental groups and local governments argue that states may pursue traditional tort claims for in-state harms; the ruling could affect dozens of similar cases nationwide.
