Are increased HCFC emissions delaying the recovery of the ozone layer?
The World Metrological Organization/United State Environment Programme (WMO/UNEP) 2006 Scientific Assessment of Ozone Depletion concludes that recovery of the ozone layer will take longer than expected, well into the second half of this century, largely because of: “an increase in HCFC-22 emissions due to larger estimated future production.” The Antarctic ozone hole is not expected to be eliminated until around 2065.
