Atmospheric insulating gas: Trends, Sources, and Prospects

Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, insulating gas will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought gaz sf6 into the climatic impact discussion aimed at reduction
