To CleanTechies : ” The increased use of hydrofluorocarbons (HFCs) in the production of refrigerators, air conditioners, and other products could play a significant role in accelerating global warming “
The United Nations Environmental Program (UNEP) study notes that the projected emissions of HFCs by 2050 could equal nine billion tons of carbon dioxide — or about one-third of current CO2 emissions.
HFCs were introduced in the 1990s to replace chlorofluorocarbons (CFCs), which were a threat to the ozone layer. So, this was a good idea with a strong downside.
