Yeah but they were able to reduce the acid rain, stop CFCs and slowed depletion. So those things are not great examples since they were resolved through change.
We stopped using CFC's in the United States and Europe, but Chyna and India still use them and at higher volumes than we ever did. So that change in the use of CFC's very likely did NOT reduce/slow acid rain or fix the ozone hole.
Also I did not link CFCs to acid rain. Acid rain was mainly from the use of heavy coal burning in the past. There were measures put in place back in the 80s/90s to reduce the sulfur from the coal, plus now lots of natural gas and other energy sources. So that is what reduced acid rain.
Still I agree acid rain is probably a big issue in like China since they still use a lot of coal, but are moving off of it.

Correlation does not imply causation.

That's just not true, CFC levels plummeted in the from the late 80s and onward.
India and China don't account for even a fraction of the peak in the 80s when the issue was discovered and banned.
They even noticed a spike a year or two ago and traced it down to the source.
China peaked in 1998 at 50 ODP Tonnes of CFCs, but almost zeroed out by 2008. the world wide peak was ~1000 ODP Tonnes in 1986.
