24,000 times more harmful to the climate than CO₂: Measurements reveal SF₆ gas emissions in Germany‎

Sulfur hexafluoride (SF6) is a chemically stable, colorless, odorless, and non-toxic gas. It is used all over the world, primarily as an insulating and protective gas in electrical switchgear within medium- and high-voltage engineering. In the past, it was also used in Germany as a filling gas for sports shoes and as an insulating gas in soundproof windows until this application was banned in 2006.
