Greatly reducing the rate at which we were going for CFCs. China has more than made up for our lack of CFC production by doubling down on hCFCs. Combine that their with blatant disregard for any environmental regulations and I don't see how the overall level has decreased to such a significant amount to declare it the reason the ozone is improving over the last 10 years. Especially since the other green house gases have still be increasing.
