Potential replacements for the chlorofluorocarbon (CFC) chemicals now extensively used as refrigerants, propellants, bubbles in plastic and cleaning fluids have already been identified.

Contrary to his assertion, however, virtually all relevant researchers say the link between CFCs and ozone depletion is based on unassailably solid scientific evidence.
