Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

A recent study suggests that the UK’s use of gaz 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 insulating gas to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
