The measurement of greenhouse gases (GHGs) has been crucial in understanding the Earth System and reducing climate change. Nondispersive infrared (NDIR) spectroscopy is one of the best-established methods for measuring GHG concentrations, starting by sucking the gas into a cell. Countries estimate their emissions from various activities and sectors, and need to cut them faster to avoid a climate crisis.
The web page explains the methods and sources used by Australia and CSIRO to estimate and monitor greenhouse gas emissions, as well as the trends and changes in global emissions. The strong greenhouse gas sulfur hexafluoride (SF 6), a manufactured gas used as an electrical insulator, provides estimates on total greenhouse gas emissions, including methane emissions and nitrous oxide emissions, which are measured in carbon.
Human activities, such as burning fossil fuels and changes in land use, release greenhouse gases that trap heat in the atmosphere. Carbon dioxide is responsible for most of global warming, although methane and other greenhouse gases also contribute to climate change. The National Institute of Standards and Technology (NIST) develops tools and standards for accurately and directly measuring GHG emissions based on atmospheric observations.
Measuring the amount of each greenhouse gas in the atmosphere acts as a check against bottom-up derived emissions estimates. The Cape Grim measurement station uses emission inventories and measurements to convert measurement and satellite data from concentrations into emissions and their various impacts. Radiative forcing is calculated using parameterizations that relate the measured concentrations of greenhouse gases to radiative forcing.
The NIST GHG Measurements Program develops technologies to measure emissions directly based on atmospheric observations from towers, aircraft, and satellites. Countries report their emissions through a “bottom up” approach, where national emissions are estimated by combining data on various activities and sectors.

I don’t believe you are even close in your hypothesis. First of all there is no Oxygen in Natural Gas CH4. If you want to guess at how much is burnt just by what is sold you could at least look on a Periodic Table, look up the atomic mass of each element then work from there. Also, back to your bogus Natural Gas Calculation, the weight could not possibly be 410 million tons of CH4, maybe 410 million tonnes, it is metric. In order to get Imperial measurement divide by 2.20.
