About
Source: ghgsat.comGHGSat describes itself as “a global GHG emissions monitoring company delivering independent greenhouse gas insights through the world’s largest dedicated satellite constellation and advanced aircraft sensors.” It says its “facility-level data and analytics help operators protect revenue, improve asset performance, and enable governments to design effective, evidence-based climate and energy policy.” Its own history records that founder Stéphane Germain saw the measurement gap as “a solvable engineering problem” — to “Miniaturize a high-resolution gas detection sensor into a microsatellite that could measure precisely” — and that “In 2016, GHGSat launched Claire—the world’s first commercial satellite for greenhouse gas emissions monitoring from space”, complemented from 2022 by “aircraft carrying the same patented sensor”.
Secured $47M CAD in September 2025 from Yaletown Partners, Fonds de solidarité FTQ and BDC Capital (equity) plus National Bank and EDC (debt) — $173M CAD raised since founding. spaceq.ca
Launched two new methane-monitoring satellites during COP30 in November 2025, bringing its fleet to 16 satellites in orbit. wastedive.com
Announced plans in November 2024 to grow its constellation from 12 to 21 satellites by the end of 2026. spaceq.ca
