the rich who are mostly the problem here

while it's true that the rich are pollution way more than most people - on a population-size it's still just a drop. If you can make everyone reduce their pollution by 10% that's more reduction in total that cutting the pollution of the top 0,1% in half.

Sure that second part is needed as well (if only to make those "I don't have to change anything"-statements like yours invalid) but it's not nearly as effective as putting measures in place that influence everyone
