Maybe, if China would curtail their CFC usage perhaps.

...A recently reported slowdown in the decline of the atmospheric concentration of CFC-11 after 2012, however, suggests that global emissions have increased...

We show that emissions from eastern mainland China are 7.0 ± 3.0 (±1 standard deviation) gigagrams per year higher in 2014–2017 than in 2008–2012, and that the increase in emissions arises primarily around the northeastern provinces of Shandong and Hebei. This increase accounts for a substantial fraction (at least 40 to 60 per cent) of the global rise in CFC-11 emissions.

Still, the Montreal Protocol is a good example of what can be achieved when we finally reach an imminent crisis.

That's from 2019, they have since reduced the leaks, this from 2021: https://www.nature.com/articles/s41586-021-03277-w

Great news, thanks for the update.
