Can track it and then in fact they are working with google using an ai tool to under map the map the underlying infrastructure so there is a plume of methane that would drift and they can then work out on the basis of winds blowing and track back to identify exactly what has come from within a companys infrastructure. On that, it is a powerful warming gas with 80 times the Warming Potential of Carbon Dioxide but crucially hanging about forfar dioxide but crucially hanging about for far less dioxide but crucially hanging about forfar less time so 12 dioxide but crucially hanging about for far less time so 12 years compared to centuries for Carbon Dioxide to what it means is if we can reduce emissions of methane, we can reduce emissions of methane, we can begin to slow Climate Change much more quickly and methane is a big contributor with one third of all Climate Change of experience since the beginning of the Industrial Revolution from methane so really important target and a really use
