GHGSat Inc. operates a satellite constellation for monitoring targeted greenhouse gas emitters. Its GHGSat D satellite demonstrates a miniature hyperspectral SWIR imaging spectrometer designed to detect emissions from sources such as tailing ponds, landfills, and industrial stacks including flaring and venting.
