I like the plots on ES.24 that show the effect the regulations have on global warming (the older replacement coolants were powerful greenhouse gases). See that curve? It's going down. If the regulations are followed (and we have good precedent that they will be) we've been spared several centi-degree in warming by 2100.
This is the only really positive news I've heard so far in the context.
Unless there was something else to stop the emission of CFCs, it would be huge by now, no question!
If anyone wants to know about the current state of the ozone hole, here's the newest report:
