GHGSat

What GHGSat does

GHGSat Inc. is a privately held Montreal, Canada-based company founded in 2011 by Stephane Germain that operates the world's largest commercial constellation of high-resolution greenhouse gas monitoring satellites. Its technical core is a patented Wide-Angle Fabry-Perot (WAF-P) imaging interferometer deployed on small satellites (20x30x40 cm), delivering ~25m spatial resolution and a 100 kg/hr methane detection threshold with ±20% quantification accuracy. By November 2025 the constellation had grown to 16 satellites and is complemented by an airborne sensor (DATA.AIR), third-party data integration (Global Survey) over Sentinel-2 and TROPOMI, and the SPECTRA analytics platform for emissions visualization.

GHGSat's primary customers are carbon-intensive enterprises — major international oil and gas operators (ExxonMobil, Aramco, TotalEnergies, Chevron, Shell, Petrobras, SOCAR, Cheniere, Comstock Resources), coal mine operators, waste-management companies including Veolia, and power generation and agriculture emitters. Governments and regulators (UK Space Agency, Environment and Climate Change Canada, NASA via CSDA) and NGOs (UN organizations via IMEO, Clean Air Task Force) form a secondary buyer base. Revenue is generated through subscription access to satellite and analytics data products (Abundance Dataset, Concentration Maps, Emission Rates), custom airborne monitoring campaigns, and emissions analytics sold on annual or multi-year contracts. The go-to-market is enterprise field sales with dedicated Oil & Gas and Industry & Government teams and a "Request a Demo" / "Talk to an Expert" conversion model.

The company has raised approximately $126M+ in cumulative funding since inception across multiple rounds, including a $45M Series B (July 2021), a $20M CAD SDTC grant (November 2021), a ~$44M round (September 2023), and a $47M round (September 2025) led into global expansion. It operates from five offices (Montreal HQ, Calgary, Ottawa, Houston, London), has 150+ employees, and maintains strategic alliances with NASA CSDA, ESA Third Party Mission, OGCI Climate Investments, Carbon Mapper, SRON, UNEP IMEO, JOGMEC / Mitsubishi Electric, Petrobras / MAVIPE, the Uzbek Space Agency, and the POSEIDON European Horizon program.

Core offering

GHGSat operates the world's largest commercial constellation of high-resolution greenhouse gas monitoring satellites (16 satellites) equipped with patented WAF-P imaging spectrometer technology to detect and quantify facility-level methane and CO2 emissions. It sells subscription-based satellite data (DATA.SAT), airborne monitoring campaigns (DATA.AIR), third-party satellite data analytics (Global Survey), and emissions intelligence services through its SPECTRA platform to industrial operators and governments worldwide.

Product overview

GHGSat offers a comprehensive satellite and aircraft-based greenhouse gas emissions monitoring platform consisting of four core products: DATA.SAT (high-resolution satellite data service), DATA.AIR (airborne monitoring), Global Survey (third-party satellite data access), and Emission Analytics. These are unified through the SPECTRA platform, which provides a data gateway for visualization and trend analysis. The constellation of 16 satellites enables daily monitoring worldwide, while the patented WAF-P imaging interferometer technology delivers ~25m spatial resolution for detecting emissions 100x smaller than other satellite systems.
