A federal court of appeals has ruled that the Environmental Protection Agency can regulate carbon emissions from vehicles and power plants.
A coalition of energy companies, manufacturers and individual states—including Kentucky and Indiana—challenged the rules in court. They argued that a core provision—the finding that greenhouse gases, like carbon dioxide are pollutants and pose a danger to human health—wasn’t based on science. And without that finding, they argued the federal government couldn’t set standards for vehicle and power plant carbon dioxide emissions.
