new type so2 quality for gas-insulated switchgears

Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) switchgear. Recently we had to change a GIS design to AIS due to an instruction from one of our clients. His concern is the global warming potential of SF6. While understanding the clients reasons, I'm not convinced on the argument.
