Satellite detections from Global Energy Monitor’s Global Methane Emitters Tracker, each an instantaneous rate on the date shown — not an annual total, and not a current reading. GMET attributes a plume to a type of infrastructure, not to a named facility: these were observed near this asset, which is not evidence they came from it.
