Here is a cool infograph to put the methane budget in context: https://essd.copernicus.org/articles/12/1561/2020/essd-12-1561-2020-f06-web.png https://essd.cop

Here is a cool infograph to put the methane budget in context: https://essd.copernicus.org/articles/12/1561/2020/essd-12-1561-2020-f06-web.png https://essd.copernicus.org/articles/12/1561/2020/essd-12-15... One question I raise is how much of the methane leaks related to oil & gas activity also include accurate data on abandoned oil/gas wells? The method described in the paper should perhaps in the future confirm the accuracy of the current estimates.

Yes, current data for most of these things are estimates based on complicated extrapolations. Being able to measure them more accurately, particularly in countries that don't publish any reliable information is going to be interesting. As far as I'm aware the current new info is generally summarized as "worse than we expected" since overestimates (i.e. accurate estimates) would get heavy pushback without solid data to justify them.

Every time we get better instrumentation and revise that data, the share of emission from fossil fuel handling explodes. I can only imagine it will keep growing until we have satellite surveys of all sources on the entire world.
