This sounds like a business sustainability decision rather than out of concern for the environment.
No, the business side was Trump's side.
"Sustainability" (but not in the planet-preserving / extinction-event-avoiding meaning) of fossil fuel over the next century is not at all a problem, if we wished so.
EU has been adamant that this was not the good time to go all-coal for example.
They could have done just that but no, the whole population and the politics are against (except in a few illiberal "democracies").
Even in the US there is a lot of work done recently to patch the methane leaks in gas fields, for example, which have been spotted as big emitters (by negligence or lack of enforcement).
