Sources of the pollutant

The sulphur hexafluoride (SF6) group of substances is produced exclusively by chemical synthesis and used in a variety of technical applications, for example as a dielectric coating agent and circuit breaker in electrical equipment and as a protective gas in magnesium smelting.

 

Effect of the pollutant

SF6 contributes to the greenhouse effect. It has a Global Warming Potential (GWP) of 22 800, i.e. 22 800 times the GWP of CO2, the reference greenhouse gas (GWP CO2 = 1) (GWP values from the Intergovernmental Panel on Climate Change (IPCC)'s fourth assessment report published in 2007).

At high concentrations, SF6 can cause asphyxiation by starving air of oxygen.

 

Classification of the sub-sectors with the highest emission levels* in 2015

Classification Sub-sectors Share of sub-sector in total national emissions in mainland France
1 Electricity production 40%
2 Industrial and transport equipment including: 37% including:
Other use of SF6 22%
Electric equipments 15%
Electronic components manufacturing 0.9%
3 Non ferrous metals production 7.4%
4 Tertiary sector 7.3%

*: one sector (of six altogether: energy transformation, manufacturing industry, residential/tertiary, agriculture/forestry, road and other transport) is broken down into sub-sectors.
