High court to decide fate of Boulder climate liability against oil majors

The Supreme Court will hear Boulder’s climate-liability suit against ExxonMobil and Suncor, marking the first high‑court review of local climate accountability cases. A ruling for the oil companies could preempt state claims and void similar suits, while a decision in Boulder’s favor would bolster climate-liability litigation nationwide. The Court’s ruling will hinge on federal preemption and jurisdiction, with recent EPA rollbacks potentially complicating the legal landscape.
