One consequence of activism against coal that you may be too young to remember was the spread of smoke filters in Germany. Presently, the top issue is fine particulate matter, which would need more expensive smoke filters (in power plants - open-cast mines are another thing), so the companies continue to resist. I note Greenpeace, much dismissed by our lovely technocrats, did some actions on that front.
