Sulfur Hexafluoride (sf 6) Emission Estimates for China: An

Abstract. Sulfur hexafluoride (SF 6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, SF 6 emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest SF 6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the SF 6 production sector (each about 10%).

Sulfur hexafluoride is a commonly used insulator in electricity transmission and distribution equipment. Because of its high global warming potential (GWP), CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear in 2010. As new technologies using lower or zero GWP insulators emerge, CARB staff are proposing to amend the current regulation to further reduce greenhouse gas emissions and to increase flexibility in complying with the standards.

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

gaz sf6 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).
