sf 6: The Truths and Myths of this Greenhouse Gas

sf 6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, insulating gas is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. sf6 gas is the energy industry’s “dirty little secret”: FALSE. sf6 gas is certainly no secret in the Norwegian energy industry.
