GHGSat Raises Convertible-Note Funding From Three Investors

GHGSat announced on November 5, 2026 that Mitsubishi Electric, MUFG Bank and Climate Investment invested in its convertible notes in October 2026, in a transaction intended to accelerate a satellite-based greenhouse-gas monitoring service. The Quebec-based company did not disclose the amount invested or the notes’ conversion terms.

The capital builds on a November 2024 partnership among Mitsubishi Electric, MUFG Bank, Satellite Data Services and GHGSat. The partners say the investment will strengthen that collaboration and accelerate development of a tip-and-cue service combining wide-area satellite observations with GHGSat’s facility-level monitoring. The immediate objective is to visualize emissions and identify their sources, rather than to announce a completed commercial launch.

Mitsubishi Electric invested through the ME Innovation Fund, a corporate venture capital fund it co-manages with Global Brain Corp. MUFG Bank’s investment came through Green Convertible Notes issued under GHGSat’s Green Finance Framework, which the bank also helped develop.

The framework treats GHGSat’s space-based remote-sensing business as eligible under the Green Loan Principles’ “Pollution prevention and control” category. DNV Business Assurance Japan supplied a third-party opinion on the framework’s alignment with those and related principles.

Climate Investment is an independently managed specialist investor in decarbonization technologies. It reports $1.8 billion of total committed capital across venture and growth strategies covering energy, industry, transport and the built environment. Its participation adds a specialist decarbonization investor to two Japanese partners already engaged in the satellite project.

Wide-Area Observation Leads to Facility-Level Detail

The planned service assigns different tasks to the two satellite systems. GOSAT-GW, also known as IBUKI GW, will survey wide areas and supply “tips” where greenhouse-gas emissions are suspected. Those locations will generate observation requests, or “cues,” for GHGSat’s constellation, which will conduct localized, high-resolution observations. The division of labor is designed to narrow the search before using the more detailed facility-level measurements.

GHGSat says its constellation can trace methane and carbon dioxide emissions to individual industrial facilities, observe sites daily and deliver detection alerts within hours. It provides emissions intelligence to companies, governments, regulators and investors to help optimize operations and comply with environmental standards.

IBUKI GW launched on June 29, 2025. The Japan Aerospace Exploration Agency’s mission record credits Mitsubishi Electric with primary responsibility for developing the satellite and its onboard sensors. One of those sensors, TANSO-3, observes carbon dioxide and methane; the other, AMSR3, monitors the water cycle. Mitsubishi Electric’s role therefore extends from building the wide-area spacecraft to participating in the partnership developing the service.

Field Verification Precedes Commercialization

Mitsubishi Electric announced on June 25, 2026 that the Japan Organization for Metals and Energy Security, known as JOGMEC, had selected it as a contractor for the technology-verification project and that it had signed the project contract. The work runs during the fiscal year ending March 2027, with Mitsubishi Electric serving as prime contractor.

The project is intended to verify accurate methane detection and quantification under field conditions and establish the technical requirements and operating procedures needed for practical use. Those steps matter because the proposed service depends not only on spotting possible emissions across large areas, but also on producing reliable measurements at specific locations.

Mitsubishi Electric will also evaluate whether satellite-based methane measurements can be applied to the Oil & Gas Methane Partnership 2.0, a United Nations Environment Programme-led, measurement-based reporting framework for the oil and gas industry. It plans to compile the findings for demonstrations and eventual commercialization. Its collaborators include Satellite Data Services, JGC Corporation, Mitsubishi Electric Software Corporation and GHGSat, with MUFG Bank contributing expertise.

The GHGSat financing extends a broader satellite-data buildout by the Japanese partners. On February 27, 2026, Mitsubishi Electric and MUFG Bank increased their existing stakes in Satellite Data Services through a third-party share allotment detailed in a joint announcement, after which SDS transitioned into a fully operating company. Mitsubishi Electric connects that additional investment and the GHGSat notes to a business foundation spanning satellite-data acquisition, analysis and service delivery.

The investment’s significance lies less in a disclosed financing total than in the alignment of capital, spacecraft and verification work around one service. Its commercial path depends on demonstrating that wide-area tips and facility-level cues can produce accurate methane measurements in operating conditions, then converting those results into repeatable procedures and reporting that prospective users can adopt.
