I never bought into the "ozone depletion by Freon" argument. Ozone layer is at the edge of the atmosphere and the Freon chloro-flourocarbon chemicals' molecules are heavier than air. How then does it get up there to destroy ozone? They have never really explained that to any satisfactory level........
I haven't either, to tell you the truth. The premise is that the UV rays' energy actually creates ozone by combining O2 and free oxygen into O3 (please, please keep me honest on this, folks). The CFCs suck up the free oxygen by combining with it, thereby robbing the outer layer of the atmosphere of the free oxygen needed to create the ozone and thereby suck the energy out of the UV rays.
Having said that, there is no connection between any supposed ozone layer effect and global warming. Two different issues.
Ozone is regenerated constantly by the interaction of the solar winds, and the electromagnetic forces at the poles, as well as lightning strikes worldwide, and the Viking Kitties.
Those heavy chloro-flouro-carbon molecules get to our outer atmosphere the same way those heavy ozone molecules do...
