07 02 07 Emissions of HFCs PFCs and sf 6 in Norway

In Norway, gaz sf6 was until 2006 mainly used in metal production, which is not covered by this report. Sulfr hexafluoride was added as a covering gas, unlike the PFCs that are unwanted by-products from metal production. The major use of Sulfr hexafluoride covered here is in high voltage switchgear and circuit breakers (GIS).
