News Release
We are pleased to announce that we will begin offering the "Renewable Energy RE100 Menu" for one commercial building managed by Frontier Real Estate Investment Corporation (Location: Chuo-ku, Tokyo; Representative: Toshihide Ichikawa, Executive Director; hereinafter "FRI").

The subject commercial building is Ikebukuro Square, located in the east exit area of Ikebukuro Station, and is owned by FRI, a real estate investment corporation managed by Mitsui Fudosan Frontier REIT Management Inc. MHI will supply electricity that meets RE100 requirements by utilizing tracked FIT non-fossil certificates. Based on the amount of electricity used by the building in FY2024 and the emission factor of the conventional supplier, we calculate that we can achieve an annual emissions reduction of approximately 1,600 t-CO2*. We will reduce Scope 2 and Scope 3 (indirect greenhouse gas emissions in the supply chain) emissions of the FRI, thereby strengthening our ESG initiatives and contributing to value enhancement.
*Calculated based on the amount of electricity used in the building in FY2024 (3,708,921 kWh) and the FY2023 emission factor of the conventional supplier (the latest published figure).

◾️About our corporate electricity retail business
Based on the know-how of electric power procurement accumulated through the "condominium bulk power supply service" launched in 2004, we have been developing electric power retail services for corporate customers since 2016. In January 2025, the company supplied virtually all of its electricity customers with renewable energy through the use of non-fossil certificates. With the mission of "making decarbonization not an intractable problem," we are helping various corporations and municipalities decarbonize by providing electricity services that enable them to both reduce electricity costs and decarbonize their operations.
◾️Background of this initiative
Mitsui Fudosan Frontier REIT Management Inc. is responsible for real estate investment trust asset management as a member of the Mitsui Fudosan Group and manages the assets of FRI, a REIT specializing in retail facilities. In response to the increasing social demands of recent years, the role of asset management companies has expanded to include not only improving the material value of properties as investment targets, but also promoting sustainability through real estate investment. Under these circumstances, the reduction of Scope 2 and Scope 3 emissions, which account for a large portion of CO2 emissions from business activities, has become one of the most important themes, and the fact that this initiative will reduce CO2 emissions from the subject properties has been highly evaluated.
We will continue to provide energy solutions that both decarbonize and reduce costs to a wide range of industries and corporations, embodying our mission of "making decarbonization less of an intractable problem.
