  • Blog | Why does SF6 switchgear still dominate the market

    Jul 01, 2020Just one kilogram of SF 6 released into the atmosphere is equivalent to 23,500 kg of CO 2 —making it by far the most potent greenhouse gas. SF 6 sticks around too, staying in the atmosphere for more than 3,200 years. There’s a reason SF 6 is one of only seven greenhouse gases listed in the Kyoto Protocol and the Hazardous Substances Data Bank
