The changes necessary to mitigate acid rain and the ozone hole didn't threaten existing oligopolies.

Acid rain was "easy" to solve by shipping production overseas (which benefits the rich, since production costs go down), slapping scrubbers onto emitters (whose costs could be passed on to consumers via fees or tax breaks), or changing the formulation of stuff getting burned. The rich stayed rich without changing their business model.

AFAIU, CFCs (and other ozone depleting compounds) had analogs that were relatively easy to use without changing processes. Once again, no yachts were harmed in the making of that solution.

Addressing climate change means we have to change how we do everything: transportation, agriculture, and manufacturing. Even band-aid solutions like EVs and renewable power require minor change and are getting a shit tonne of pushback. Doing the hard work necessary to keep our climate stable (and avoiding possible extinction) would invalidate a bunch of business models.

Hence the resistance.
