It's fuzzier than that. For example, there is a lot of momentum behind carbon capture and storage research and implementation that was built up under previous presidents (yes, even pre-Obama), and it would take a great deal of work for congress to re-route funding that the Department of Energy has already allocated. Even 45Q tax credits for capturing and storing CO2 started working through the federal government before the current administration, with the partial goal of determining what a carbon price would actually be.

CCS technology may be currently used to say "look, clean coal!", but it's still useful and important for a low-carbon future.
