Former AG Barr: Climate change lawsuits could cripple energy companies
Former U.S. Attorney General Bill Barr warned that a Supreme Court case, Suncor v. Boulder, could lead to billions in damages against energy companies like Suncor and ExxonMobil for climate change contributions. Barr argued that state nuisance laws should not be used for national or global issues. Experts noted potential economic impacts on energy prices and U.S. competitiveness.
