Gotta start somewhere. Europe will follow soon.
Hopefully, the participants will be smart enough to start applying the tax to imports from places like China, to incentivise them to change their ways or become uncompetitive. Might even see some manufacturing come back here, using less wasteful processes, using technologies that can then be exported to others.
And we'd still be paying less tax than anyone else in the western world, just like we do now.
But that's probably too "lefty idealism" for you...
