Suncor

The US Supreme Court has agreed to hear the City of Boulder's lawsuit against oil company Suncor, a case the city has pursued for years to hold energy firms financially responsible for climate change damages. The ruling could set a nationwide precedent for whether local governments can sue fossil fuel companies in state courts over climate harms.

US states facing court setbacks on climate legislation are fighting to keep their laws alive. New York's climate superfund law, which would make fossil fuel companies pay for climate damages, is being challenged, with Suncor among the companies targeted in litigation echoed by a Colorado Supreme Court case brought by Boulder. Reporting outlines how courts keep blocking such laws and how states are responding with new legal strategies.
