    SF6-free solutions are important because SF6 is a potent greenhouse gas (GWP 23,500) with a long atmospheric lifetime (850 years). The rate of rise of atmospheric SF6 concentration is increasing annually, and the electric power sector is accountable for the majority of these emissions. Therefore, SF6-free solutions are needed.
