With more than 80 times the short-term warming power of carbon dioxide, methane is a significant climate threat. But finding and fixing methane leaks is no small feat and ground-based detection methods struggle to pinpoint this colourless, odourless gas. In this episode of Solve for X, host Manjula Selvarajah sits down with Stéphane Germain to discuss how his company’s fleet of microsatellites is transforming methane detection. By capturing data from orbit, this satellite technology offers new insights into methane sources, reshaping how we monitor and reduce emissions for a cleaner future.

Featured in this episode:

• Stéphane Germain is the CEO and founder of GHGSat, a global leader in satellite-based methane monitoring. With a background in aerospace engineering, he leads the development of microsatellites that detect greenhouse gas emissions from space, delivering critical data for climate action.
