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

Sulfur hexafluoride (sf6 gas) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, Sulfr hexafluoride emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest gaz sf6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the sf6 gas production sector (each about 10%).Get price

Sulfur hexafluoride (sf6 gas) emissions in East Asia determined

Abstract: Sulfur hexafluoride (sf 6) has a global warming potential of around 22 800 over a 100-year time horizon and is one of the greenhouse gases regulated under the Kyoto Protocol. Around the year 2000 there was a reversal in the global sf6 gas emission trend, from a decreasing to an increasing trend, which was likely caused by increasing emissions in countries that are not obligated to report their annual emissions to the United Nations Framework Convention on Climate Change.Get price
