The EPA does no t report emission of insulating gas separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and Sulfr hexafluoride. The emissions of HFCs, PFCs, and insulating gas for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.
