Apr 12, 2021 · This is just the UK, SF6 stays in the atmosphere for a minimum 1000 years where as CO2 100 years. SF6 is on the increase the US expect a 6.2% increase over the next 6 years. SF6 might not damage the Ozone but it will accelerate Global Warming given the fact that it stays in the atmosphere longer can cause more damage over a longer period of time.
