Chemicals in cooling and refrigeration systems can be far more destructive to the environment than carbon dioxide. It’s time to phase them out

Our planet’s fragile ozone layer is on a path toward full restoration by about 2050. But there’s a hitch: the success has hinged largely on replacing ozone-depleting substances with hydrofluorocarbon (HFCs) – chemicals we now know are highly damaging to the environment. It is time to reduce these pollutants.

Air conditioning, refrigeration, and insulation often contain factory-made HFCs. They are greenhouse gases that can be hundreds or thousands of times more potent than carbon dioxide in damaging our climate system, yet their global use is rapidly increasing every year.
