In response to a survey issued by the American Energy Alliance, Republican presidential candidate Donald Trump gave a firm “no” to the question “Do you support a carbon tax?” He also indicated his opposition to using the social cost of carbon in calculation of cost-benefit analysis for federal rulemakings, but did not elaborate beyond his one-word response in either instance.

The candidate was also asked whether he would support an eventual end to all energy subsidies, to which he responded:

“This is an issue for Congress and the people they represent. Subsidies distort markets and should be used only when national security is at stake. Eventually, all subsidies should end so that the demand for energy will set prices, allow consumers access to the best values and encourage all facets of the energy industry to do all they can to keep their particular source competitive.”

Trump has been an outspoken opponent to climate change action.
