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

    Abstract. Sulfur hexafluoride (sf 6) 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%).
