Initiatives to Reduce GHG Emissions and Achieve RE100
Mitsubishi Estate recognizes climate action as one of its key management priorities, and is promoting reductions in greenhouse gas emissions arising from its business activities with targets to reduce Scope 1 and 2 emissions by 70% or more and Scope 3 emissions by 50% or more by FY2030. In FY2025, the Company reached its 2030 targets significantly ahead of schedule and also achieved a 100% renewable electricity procurement rate.* These achievements were the result of the Company working to ensure energy-saving measures, install highly efficient equipment, optimize energy consumption through operational improvements at office buildings and retail properties owned and operated by Mitsubishi Estate, in addition to efforts to increase the introduction and procurement of renewable energy.
Going forward, by diversifying procurement methods and strengthening collaboration with external partners, Mitsubishi Estate will continue to ensure a stable supply of renewable energy and pursue procurement with additionality that contributes to the creation of new power sources. The Company will also promote energy conservation and other measures through utilization of next-generation technologies and collaboration with tenants. Through these initiatives, Mitsubishi Estate will increase the environmental performance of owned assets and push for further decarbonization across the entire value chain.
- Achievement of 100% renewable energy use under the standards of international initiative RE100 will be verified through the CDP disclosures for FY2026.
Renovation Business Promoting the Effective Use of Existing Urban Properties
The Mitsubishi Estate Group works on renovation projects that utilize existing buildings in Japan and overseas with the aim of both reducing environmental impact and increasing asset values. In London, following the completion of Warwick Court in 2022 and the commencement of construction on 1 Victoria Street in April 2025, the Group launched a large-scale refurbishment of 125 Shaftesbury Avenue in December 2025. The project will reuse approximately 75% of the existing structure, while renovating it into an office building that is equipped with the latest environmental features. In addition to enabling a significant reduction in CO2 emissions during construction compared to demolition and new construction, the project aims to reduce environmental impact across the building lifecycle by reusing materials, installing highly efficient systems, and utilizing energyefficient design and renewable energy.
In addition to these environmental benefits, the Group is drawing on its long-standing development experience in London and its global expertise in urban development to improve pedestrian circulation, enhance connectivity with surrounding neighborhoods through the creation of new public passages, and create vibrant spaces where people can gather and interact. These initiatives also contribute to enhancing the attractiveness and vitality of the area.
Going forward, Mitsubishi Estate will aim to achieve environmental and economic value by further promoting utilization of existing building stocks in various areas and will continue contributing to the development of a sustainable and appealing urban environment.
