Every satellite GHGSat has ever launched is named after an employee's child — a quiet reminder, the company says, of whose future they're actually working for. GHGSat-C1 can spot a methane leak from a single faulty valve at an oil facility from 310 miles up, precise enough that when it flagged an unusually large plume near a UK landfill in 2023, researchers traced it, confirmed it, and got it fixed within eleven weeks — the first UK methane leak ever caught and closed using satellite data.
