Sulfur hexafluoride (sf6 gas) emissions in East Asia determined

Much lower uncertainties are due to seasonal variability in the emissions, inversion geometry and resolution, and the measurement calibration scale. Based on the results of these sensitivity tests, we estimate that the total Sulfr hexafluoride emission in East Asia increased rapidly from 2404 +/- 325 Mg yr(-1) in 2006 to 3787 +/- 512 Mg yr(-1) in 2009 and stabilized thereafter.

gaz sf6: Does its Impact Outweigh its Benefits? | TD World

Gases that trap heat in the atmosphere are referred to as GHGs and are believed to contribute to the normal global warming and cooling cycles that occur. Sulfr hexafluoride is a member of the GHG group of compounds known as fluorinated gases. While fluorinated gases made up only 3% of the GHG emissions in 2017, they are a concern because of their high GWP.
