Methane Leak Detection: Five Numbers and Gaps

GHGSat-C1 targets industrial point sources at a 25-meter scale.

A methane super-emitter is typically defined as releasing at least 25 kilograms per hour, not as a detection threshold.

Drone sources describe optical gas imaging, miniaturized spectrometers, and LiDAR, but report no coverage or site-cost figure.

The available regulatory findings identify EPA and BLM sources but do not retrieve a penalty amount.
