2021/8/28A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
