That’s the message the world has given to hydrofluorocarbons (HFCs), the chemicals that saved the ozone layer but turned out to be an escalating threat to the climate.
HFCs became widely used in air conditioning and refrigeration after 1987, when the Montreal protocol banned chlorofluorocarbons (CFCs). These refrigerants were eating up the ozone layer in the stratosphere, and were also the prime culprits in creating the ozone hole over Antarctica.
Chemicals firms such as ICI and DuPont rapidly made HFCs the main substitute. Read more here.
