Fracking for Europe, by a (mostly) French company, done in the United States. Would be interesting to see if methane gas emissions can be actually detected - of course they're not going to flare the gas when the extraction site is in a residential area, that would be too conspicuous. Which of course also begs the question why this has to be done in a residential area. I looked at Arlington, TX on Google Maps and realized that this must be a side effect of the American sprawl: if there is oil/gas to be extracted in the area, you have to do it in a residential area, because there is no open space to be seen anywhere nearby...

The linked video is /extremely/ opinionated and contains much misinformation. Just need to level set on that first -- > Would be interesting to see if methane gas emissions can be actually detected Obviously. But unlike in the video you need to actually use gas detectors instead of a thermal camera and look around the wellheads and gathering pipelines where the gas /is/ and not at some random compressor's engine exhaust heat. Fortunately the folks who maintain these things have qualified engineers who actually know how to use their equipment and the agencies who regulate them have standards that are actively monitored and enforced without requiring the oversight of well meaning old ladies with too much free time. > why this has to be done in a residential area Because it's where the field is, and you have to build gathering systems where the wells are. There is even more oil and gas infrastructure crammed into urban Los Angeles than there is in DFW though.

  Methane can be detected by optical spectrometry. Since methane is not only a pollutant but also a very potent green house gas (30x stronger than CO2), efforts are made to map the sources from the air and space [0-2]. Edit: I found the FLIR camera shown in the video. It is made for gas emission analysis: https://www.flir.com/products/flir-g-series/ https://www.flir.com/products/flir-g-series/ [0]https://www.optica-opn.org/home/newsroom/2022/february/mapping_methane_with_spaceborne_spectrometry/ https://www.optica-opn.org/home/newsroom/2022/february/mappi...
