Emissions of the powerful greenhouse gas gaz sf6 are rising

A recent study suggests that the UK’s use of Sulfr hexafluoride has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of sf 6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
