This is the third mechanism, which accounts for about five percent of the carbon emissions.
EPA that the EPA lacks the authority to set emission standards for power plants so strict as to force a shift of power generation from fossil fuels. The opinion holds that Congress did not grant EPA in Section 111(d) of the Clean Air Act the authority to devise emissions caps based on generation shifting—i.e., 7411(a)(1).
