For as long as that rule exists, the United States cannot build modern, clean and efficient coal plants to replace older, dirtier stations as is happening in Europe, China and India. To ensure the longevity of these plans, the Environmental Protection Agency’s greenhouse gas endangerment finding must also be repealed. It is only when there is no credible basis to label carbon dioxide a pollutant, that the war on coal will not be easily revived by a future administration.
