    Electric utilities are under increasing pressure to address the issue of SF 6 (sulphur hexafluoride) leaks from substations. SF 6 is widely used as an insulator in high voltage circuit breakers and switchgear, but it is also a greenhouse gas. In the USA, the Environmental Protection Agency has recently begun asking utilities for a voluntary reduction in SF 6 emissions.
