What Is sf6 gas? and How Is It used?Is gaz sf6 A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of Sulfr hexafluoride Emissions Difficult? Do Better Solutions Exist?ConclusionSulfr hexafluoride is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry Sulfr hexafluorideis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.

European Commission President Ursula von der Leyen recently proposed a “European Green Deal,”—Europe’s new growth strategy, which seeks to transform the European Union (EU) into a climate-neutral economy by 2050. This objective builds on the commitments made by the EU under the Paris Agreement to reduce greenhouse gas emissions by at least 40 percent by 2030 compared to 1990. The European Commission plans to enshrine the 2050 climate neutrality objective into law in March 2020. The European Council endorsed the Green Deal objectives, despite opposition from Poland. The discussions are set to continue in June 2020. According to the objective of the “European Green Deal,” carbon emissions would have to be reduced by at least 50 percent by 2030 compared to 1990 levels.
