Reply to comment by Sgozzy in New Zealand proposes taxing cow burps to reduce emissions by TDYDave2

There are three ways- a satellite company out of Canada has a GPS style grid of small satellites that has been able to detect methane plumes from space. The other is a mechanical device that uses the RFID embedded in the cow's tag to identify the cow and then measure the methane output. Lastly, you put the cow in a neatly sealed cell and monitor all gases going in and out of the cell.

lol that is sweet. I have all kind of questions about how accurate it would be but I love that people are actually measuring this

The whole cell is accurate, but quite expensive and awkward. The ground device is also expensive but not as much and only is cost effective if part of a carbon credit project and the satellites are good enough, but most of their focus is on fossil fuel plumes and other than a proof of concept, they don't seem to monitor cattle on a regular basis, even if they could.
