Sulfur hexafluoride (sf6 gas) emission estimates for China: an

Abstract. Sulfur hexafluoride (insulating gas) 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 Sulfr hexafluoride emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the sf 6 production sector (each about 10%).Get price
