The 2009 determination had served as the legal foundation for federal limits on vehicle emissions, power-plant rules, and other climate-related regulations.
Background on the 2009 finding The original finding followed a Supreme Court decision that required the agency to determine whether greenhouse gases met the Clean Air Act definition of air pollutants. Agency documents stated that the repeal removes the basis for rules that had not received direct congressional authorization.
Scope of the repeal The action affects regulations that relied on the endangerment finding for their legal justification. Officials said the change will reduce compliance costs for businesses and households that had been subject to those rules. Further agency actions to implement the repeal are expected in the coming months.
