§ Private Profile · Montréal, QC, Canada
Satellite technology company monitoring greenhouse gas emissions from industrial facilities, providing actionable data for climate mitigation.
GHGSat is a Montreal-based aerospace company that operates a constellation of satellites designed to monitor and measure greenhouse gas emissions from industrial facilities worldwide. The organization provides actionable emissions data and high-resolution insights to help diverse industrial sectors and government authorities accurately quantify and control their environmental output. In 2023, the company's proprietary satellite technology successfully assisted local authorities in identifying and halting a significant methane leak located in England. Prior to establishing the enterprise, the chief executive gained extensive corporate strategy experience consulting for Bain & Company and held senior management roles across the commercial aerospace sector. The firm's leadership was recognized on the TIME100 Climate list as one of the top 100 individuals driving global business climate action. To address a market need for consistent environmental measurements, GHGSat was founded in 2011 by Stéphane Germain.
GHGSat has raised $182.3M across 7 funding rounds.

GHGSat is a Montreal-based technology company that builds and operates the world's largest commercial constellation of high-resolution satellites and aircraft sensors to monitor greenhouse gas emissions, primarily methane and CO2, from industrial sites.[1][2][8] It serves energy, mining, oil & gas, waste management, and agricultural sectors by providing precise, actionable data that helps operators detect leaks, reduce emissions, comply with regulations, and support climate goals—at a fraction of the cost of traditional methods.[3][4][5] The company solves the critical problem of inaccurate or infrequent emissions tracking in hard-to-access facilities worldwide, enabling data-driven decisions for businesses, governments, and regulators amid rising demands for transparency in carbon management.[1][6]
Founded in 2011 with 101-250 employees, GHGSat has achieved strong growth momentum through satellite launches, partnerships like Canada's Oil Sands Innovation Alliance (COSIA), and expansion into predictive analytics combining its data with third-party sources.[1][3][6]
GHGSat was incorporated in 2011 in Montreal, Quebec, pioneering high-resolution remote sensing of greenhouse gases from space.[3][7] While specific founders are not detailed in available sources, the company emerged from the need to address gaps in emissions monitoring for dispersed industrial operations, such as oil sands and shale gas sites, where traditional ground-based methods were costly and limited.[6] Early traction came from collaborations starting in 2015 with COSIA to measure challenging emissions sources in Alberta's oil sands, validating its satellite and aircraft tech against conventional tools.[6] Pivotal moments include developing the first small-satellite sensor for detecting emissions as low as 100 kg/hr, earning recognition as a World Economic Forum Technology Pioneer in 2019, and rapidly expanding its satellite fleet for global coverage.[2][5][8]
GHGSat rides the wave of climate tech and GEOINT unbundling, where satellite constellations address gaps in emissions data amid global net-zero pledges and methane pledges like the Global Methane Initiative.[4][6] Timing is ideal as regulations tighten (e.g., EU methane rules, U.S. oil & gas reporting), while energy transition demands verifiable carbon footprints—market forces favoring scalable, non-intrusive monitoring over expensive ground surveys.[1][5] It influences the ecosystem by providing independent data to emitters for compliance, regulators for enforcement, and scientists for modeling, accelerating decarbonization in high-emission sectors like oil & gas and mining.[2][6]
GHGSat is poised to dominate emissions monitoring as its constellation grows, expanding to more trace gases, air quality, and natural sources beyond current GHG focus.[4][8] Trends like AI-driven analytics, stricter global policies, and carbon markets will amplify demand, potentially evolving it into a full-stack climate intelligence platform. Its pioneering edge positions it to shape industry standards, tying back to its core strength: transforming satellite data into emissions reductions that scale worldwide.[2][7]
GHGSat has raised $182.3M across 7 funding rounds. Most recently, it raised $33.9M Other Equity in September 2025.
