    But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earths atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to
