Join hosts Lysandra, Dave, and John for an in-depth conversation with Stephane Germain, Founder and CEO of GHGSat Inc., whose satellites directly measure methane and CO₂ emissions at the facility level. This episode dives into the science, technology, and real-world implications of replacing proxies and estimates with hard data, finally showing operators what’s actually happening on the ground.
Stephane explains how their satellites identify greenhouse gases using spectral fingerprints, how snapshots taken over time build a statistically meaningful record, and why direct measurement often reveals emissions that are far higher than what traditional models predict. The discussion ranges from the physics of methane detection to the economics of leak mitigation, touching on agriculture, oil and gas, waste, mining, and the global regulatory landscape.
We also explore the human side of emissions monitoring: why estimates tend to be conservative, how culture and incentives shape reporting, and what it takes to verify data with academic institutions, NASA, and the European Space Agency. Throughout, Stephane shares vivid case studies that show how satellite data uncovers hidden losses, improves safety, and creates real commercial value.
This episode is for anyone curious about the future of emissions measurement and the rapidly growing role of space-based climate technology.
