Supreme Court to decide if states can hear climate lawsuits against oil companies.

The U.S. Supreme Court will hear a case brought by ExxonMobil and Suncor Energy seeking to block a climate lawsuit filed by Boulder, Colorado, which alleges the companies misled the public about fossil fuel impacts and are liable for climate-related damages. The case, one of many similar suits by cities and counties, could determine whether state courts can hear climate liability claims or if such matters must be handled federally. The Trump administration supports the oil companies, arguing state lawsuits interfere with federal climate policy, while Boulder contends states have authority to address out-of-state harms. The decision may shape the future of climate litigation nationwide.
