Exxon

ExxonMobil is taking its fight over climate change liability to the US Supreme Court, in a move that could shield its Houston-based oil operations from climate-related lawsuits. The company is seeking to limit the ability of cities, counties and other plaintiffs to pursue damages over its role in producing fossil fuels that contribute to global warming. The case is being closely watched because a ruling in Exxon's favor could set a national precedent affecting climate litigation against oil companies across the country.

ExxonMobil and Suncor have petitioned the US Supreme Court to halt local lawsuits that the companies argue threaten domestic fuel production. The cases, brought at the local level, could impose liability on fuel producers. The companies contend such litigation interferes with national energy policy and interstate commerce, raising questions about where climate and fuel-related claims can be heard.
