There is a big difference between the ozone layer, acid rain and climate change.
Ozone: Required the move to different refrigerant gasses and implement measures to stop old cfc's being accidentally released.
acid rain: Required the use of low sulfur fuels.
While both were costly they were minor in comparison to climate change emissions.
The problems were incidental to the industries involved and not a something that had to happen for the industry to function.
And the big one, they industries that were required to change could profit from the change.
The complete opposite for co2 emissions.
There is no way to burn coal or oil without producing co2. So there was zero incentive from the companies and countries that profit from these industries to even look at solutions . Let alone implement them.
