Mitsubishi Electric Corp., MUFG Bank, Ltd, and Climate Investment, in October 2026, invested in convertible notes issued by GHGSat Inc., a company engaged in satellite-based greenhouse gas (GHG) monitoring.
Founded in 2011 and headquartered in Québec, Canada, GHGSat pioneered high-resolution GHG remote sensing from space. The company operates a satellite constellation capable of tracing methane and carbon dioxide emissions to individual industrial facilities, enabling emissions to be monitored at unmatched speed and scale: sites are observed at a daily cadence, with alerts about detections delivered within hours. Today, GHGSat provides emissions intelligence to companies, governments, regulators and investors to help optimise operations and comply with environmental standards.
Accurately identifying and quantifying GHG has become increasingly important for addressing global warming. Methane, the main component of LNG, has a greater global warming effect than carbon dioxide. Across the energy sector and a broad range of other industries, there is a growing need to identify exact emission sources, detect leaks swiftly, and accurately quantify emissions.
To address these challenges, Mitsubishi Electric, MUFG Bank, Satellite Data Services Co., Ltd.ii (SDS) and GHGSat entered into a partnership agreement in November 2024 to visualise GHG emissions using satellite data. Since then, the parties have been working to develop a service that uses data from GOSAT-GWiii (Global Observing SATellite for Greenhouse gases and Water cycle; IBUKI GW), which is well suited for wide-area observations, and GHGSat’s satellite constellationiv, which delivers facility-level observations, to visualise GHG emissions and identify emission sources.
Working together, the satellites can establish ‘tip and cue’ operations: IBUKI GW will conduct wide-area observations to identify areas where GHG emissions are suspected and provide ‘tips’ on potential emission sources; those tips will then be used to send observation requests, or ‘cues’, to GHGSat’s satellite constellation, triggering high-resolution localised observation of the relevant locations.
This service, with Mitsubishi Electric serving as the prime contractor, has been selected for JOGMEC’s fiscal 2026 public solicitation for a technology verification project to identify and measure GHG emission sources using satellite data.
