The US Supreme Court has agreed to hear a case, brought by Suncor Energy USA and ExxonMobil Corporation, against a climate accountability lawsuit filed by the city of Boulder, Colorado. The oil companies argue that federal laws preempt the city's claims. This marks the first time the Supreme Court has considered a climate accountability case, potentially impacting similar lawsuits across the US. A ruling against the oil companies could bolster climate litigation, while a ruling in their favor could void the Boulder case and others like it. The court will also consider whether it even has the authority to hear the case at this time. The Supreme Court's decision could be complicated by the EPA's recent repeal of a legal determination that allowed the federal government to regulate climate-warming pollution.
