  • Is the end coming for sulfur hexafluoride, the most powerful

    Oct 15, 2020 · With a global warming impact that is 23,500 times higher compared to CO 2 and an atmospheric lifetime of 3,200 years, SF 6 is the most harmful known greenhouse gas. Not surprisingly, the Kyoto Protocol lists SF 6 as one of the six greenhouse gases that are restricted for use (together with CO 2, CH 4, N 2 O, HFC and PFC).
