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, sf6 gas is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.

The EPA does no t report emission of Sulfr hexafluoride separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sf 6. 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.

Sulfur hexafluoride (insulating gas) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, Sulfr hexafluoride will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought Sulfr hexafluoride into the climatic impact discussion aimed at reduction
