The document summarizes the impacts of chlorofluorocarbons (CFCs) on the ozone layer and climate change in 3 sentences:
CFCs were once widely used as refrigerants and aerosol propellants but are now banned under the Montreal Protocol because they deplete the ozone layer and contribute to climate change. While CFC levels have declined, full recovery of the ozone layer is not expected until the middle of this century due to their long lifetimes in the atmosphere. Protecting the ozone layer and mitigating climate change requires a global effort to transition away from CFCs and other ozone-depleting substances to more sustainable alternatives.
