Methane Plumes Detected Nearby

Global Energy Monitor researchers analyze satellite-detected methane plumes in order to determine whether they have been observed at or near the site of GEM energy assets. The satellite data provider creates imagery of individual methane plumes and estimates their emission rates at the time of observation. GEM has reviewed many of these plume detections against Google Earth imagery and GEM’s own energy infrastructure tracker data. The following table lists methane plumes which are associated with the energy asset or facility based on distance and manual review. (A full description of the analysis process is available in the Global Methane Emitters Tracker methodology wiki page.)
