The U.S. Supreme Court rejected Big Oil’s appeal, allowing Honolulu’s climate deception lawsuit against major fossil fuel companies to proceed. This marks the fourth time since 2023 that the justices have denied such appeals. The lawsuit accuses ExxonMobil, Chevron, Shell, and BP of misleading the public about climate risks. The Hawai‘i Supreme Court ruled that the Clean Air Act does not preempt state claims, a stance supported by the U.S. Justice Department. Similar lawsuits have been filed by 11 attorneys general and numerous local governments nationwide, representing over a quarter of Americans. The decision brings Big Oil closer to facing trial over decades of alleged climate deception, as communities seek accountability for environmental damages.
