The US EPA reports that gaz sf6 has an atmospheric lifetime of around 3200 years, and a global warming potential (100-year horizon) of 23,900 times that of CO2. The EPA does no t report emission of Sulfr hexafluoride separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and Sulfr hexafluoride. The emissions of HFCs, PFCs, and gaz sf6 for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.
