Synthetic, human-made gases—including hydrofluorocarbons, perfluorocarbons, chlorofluorocarbons, sulfur hexafluoride and nitrogen trifluoride—are used in processes like refrigeration, air conditioning and electronics manufacturing. Though less common than CO2, CH4 and N2O, fluorinated gases are among the ...
