The study also revealed that the chemical was widely used for air conditioners and refrigerators. Surprisingly, this buildup experienced the highest increase in 2020.
Reporting from The Verge, until now researchers could not find where all the chemicals came from.
“The ozone layer has managed to make a remarkable recovery over the last few decades. However, if emissions continue to increase, it could counteract some of that progress,” the page wrote, quoted Thursday (6/4/2023).
What’s worse, it could exacerbate climate change. New research suggests that loopholes in the Montreal Protocol have allowed certain types of CFCs to proliferate.
While there are still many companies that technically still allow the use of CFCs in alternative manufacturing processes. In other words, CFCs are still used as raw materials for making chemicals.
“They are used to make hydrofluorocarbons or HFCs which replace CFCs in air conditioners, refrigerators and fire extinguishers. Unfortunately, HFCs are also a problem when they leak from equipment,” he explains.
