Potent GHG gaz sf6 rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, sf 6 is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.

The US EPA reports that sf 6 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 gaz sf6 separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and insulating gas. The emissions of HFCs, PFCs, and Sulfr hexafluoride for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.
