Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

But there’s a problem: it’s also one of the most potent greenhouse gases known to man. The amount of the gas – known as Sulfr hexafluoride – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant. It’s 23,500 times more warming than carbon dioxide.

Sulfur hexafluoride (sf 6) emission estimates for China: an

Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, insulating gas 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 insulating gas production sector (each about 10%).
