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

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. GWP is a calculation of how long the GHG remains in the atmosphere relative to carbon dioxide (CO 2) and how strongly it absorbs infrared radiation (energy). Gases with a higher GWP absorb more radiation than those with a lower GWP and thereby are believed to cause more warming of the earth.
