Yes. If you can't make big sweeping bites into the problem, make whatever bites you can.
Those bites are listed elsewhere on this forum. There were roughly 80 promises, some of which are a good idea, some of which are not. Unfortunately, in the midst of all the Russian kerfuffle Tillerson signed onto what amounts to a committment to the Paris Accords, and the ethanol mandate will be kept. Despite appointing an EPA chief who doesn't believe in AGW, Tillerson's actions effectively negate much of the potential progress that can be made.
Ethanol will continue destroying small engines where people haven't figured out how to get it out of the fuel and can't get ethanol free fuel. Some form of cap and trade remains a possibility. There is little advantage to building oil pipelines when the very market comes under attack by the same administration's actions.
As far as I am concerned, Gorsuch is the salient accomplishment, and the jury is still out on how he will rule.
