Sulfr hexafluoride: The Little Gas That Could… Make Global Warming Worse

Mar 25, 2021 · China itself is believed to be responsible for 36% of global SF 6 emissions. Even some developed countries , including the U.S. and UK, may grossly underestimate their output.

Sulfur hexafluoride (Sulfr hexafluoride) emission estimates for China: an

Abstract: Sulfur hexa fluoride (Sulfr hexafluoride) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, sf 6 emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest insulating gas emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the Sulfr hexafluoride production sector (each about 10%).
