Overview
- Boulder County and the city of Boulder filed the lawsuit in 2018, seeking compensation for climate-related damages caused by ExxonMobil and Suncor’s alleged decades-long misrepresentation of fossil fuel risks.
- The Colorado Supreme Court ruled that Boulder's claims under state common law are not preempted by federal law, rejecting arguments that the lawsuit amounts to regulating greenhouse gas emissions.
- The case now returns to Boulder District Court for further proceedings, marking a significant step in state-level climate accountability litigation.
- Dissenting justices warned of potential 'regulatory chaos' and called for U.S. Supreme Court intervention, highlighting concerns over the broader implications of such lawsuits.
- Similar lawsuits by municipalities across the U.S. have faced mixed outcomes, with the U.S. Supreme Court consistently declining to intervene in state-level climate cases.
