The Trump administration’s “America First” energy policy seeks to increase the output of oil, gas and coal, boost employment and make the United States independent of foreign suppliers. But because of its focus on aiding the coal industry and reducing environmental protections, the plan has drawn criticism from environmentalists and a wide range of officials. Many see the moves as outdated because natural gas has already surpassed coal as the leading source of electricity generation. President Trump’s decision to pull out of the Paris climate agreement, an international accord designed to cut greenhouse gas emissions, also has drawn harsh criticism, even from many corporate leaders. Corporations, as well as state and local government officials, are pledging to meet greenhouse gas targets set under the accord.
