Environmental Performance
Based on the Sustainability Policy items “1. Climate change initiative (promoting decarbonization and strengthening resilience)” and
“2. Contribution to resource conservation including water and resource recycling”, JRE has set reduction targets for energy consumption and greenhouse gas emissions in order to improve the environmental performance of its real estate portfolio.
In order to achieve these targets, JRE’s asset management company, JRE-AM implements measures to improve the operational performance of buildings, conduct energy efficiency retrofits, and engage tenant on energy efficiency based on its “Energy Conservation Policy”, which stipulates operational policies for improving energy efficiency of the real estate portfolio, and “GHG Emissions Reduction Policy”, which aims to create a decarbonized society.
CO2 Emissions Reduction Targets and KPIs for FY2030
In response to the growing concerns over the risks from climate change, JRE recognizes that reduction of greenhouse gas (GHG) emissions is of critical importance in light of enhancing the sustainability of our future business. We have been working to reduce energy consumption and GHG emissions of its portfolio, and has achieved a lower consumption and emissions than the previous levels. We verified the possibility of reducing CO2 emissions from over 70 of our properties and established reduction targets for FY2030. Going forward, JRE will contribute to a shift to a decarbonized society through the reduction of GHG emissions while securing its preparedness to natural disasters and other phenomena arising from climate change.

Brownfield Redevelopment GRAND FRONT OSAKA
JRE acquired GRAND FRONT OSAKA (North Building) and GRAND FRONT OSAKA (Umekita Plaza and South Building) in October 2021, ensuring that countermeasures have been implemented against the brownfield land (former yard site) where groundwater and soil contamination has been confirmed.
The north district of the Osaka Station in which GRAND FRONT OSAKA is situated is the largest terminal in western Japan where seven stations and 12 railway lines converge. The property is directly connected to JR Osaka Station via a pedestrian deck and enjoys close proximity to Umeda Station on the Hankyu and Hanshin lines as well as various subway lines, making transportation extremely convenient.
In terms of the environment, the property has a high standard of safety due to its excellent earthquake resistance from adoption of the latest damping structure. The property also forms a network of water and greenery in unison with the several blocks with greening, water features, etc. on rooftops and on the ground, realizing a harmonious environment as a whole.
Moreover, the property employed highly effective low‐CO2 technologies such as natural ventilation, high‐efficiency heat source systems, and solar power generators as well as establishing a network of Building Energy Management Systems (BEMS) of each of its buildings which centralizes control of energy consumption as an entire property. As initiatives for the entire development area, an organization called Town Management Organization (TMO) is set up and it develops city‐wide CO2 reduction management in a bid to realize a decarbonized society. As such, the property has been selected by the Ministry of Land, Infrastructure, Transport and Tourism as “Leading Low‐CO2 Model Business for Residences and Buildings”, serving as an “environmental showcase leading the realization of a sustainable society.”
Consideration to urban greenery and biodiversity
JRE’s sustainability policy stipulates that it will contribute to conserving biodiversity and ecosystem. JRE gives consideration to biodiversity in the operation of buildings by endeavoring to conserve and improve the ecosystem on property premises and adjacent urban green areas and natural areas.
Note that while JRE does not invest in new development projects, the sponsor Mitsubishi Estate Co., Ltd. pursues sustainable land use using certification systems such as Association for Business Innovation in Harmony with Nature and Community (ABINC) certification and SITES certification at the time of development.

Proactive Introduction of Renewable Energy
Accelerated Use of Electricity Made from Renewable Energy (RE100 Compatible)
JRE accelerates the use of electricity made from renewable energy recognized by RE100* ("renewable electricity"). As of the end of September 2024, JRE has completed the switch to renewable electricity at its properties of 100% operational control. JRE proactively introduces renewable electricity into the buildings other than 100% operational control and further accelerates the reduction of CO2 emissions.
RE100 is the global corporate renewable energy initiative bringing together hundreds of large and ambitious businesses committed to 100% renewable electricity.
JRE’s Switch to Renewable Electricity (Outline)
Utilization of Onsite Renewable Energy
JRE promotes the reduction of CO2 through the utilization of renewable energy in solar generation at some of the office buildings owned by JRE such as Otemachi Park Building, the ARGYLE aoyama, Shinjuku Front Tower, Toyosu Foresia, Toyosu Front, GRAND FRONT OSAKA (North Building) and GRAND FRONT OSAKA (Umekita Plaza and South Building).
Otemachi Park Building
Reuse and Recycle of Water
Some of the buildings owned by JRE are equipped with facilities for reusing rainwater and greywater, as JRE endeavors to reduce the consumption of tap water.
Environmental contribution in collaboration with tenants
Aiming to make environmental contributions by collaborating with tenants, JRE has been gradually introducing Green Leases in terms of both operational improvement and efficiency retrofits.
Moreover, JRE is conducting diverse sustainability initiatives together with our tenants.
Introduction of Green Leases
JRE works to reduce environmental impact in cooperation with tenants by promoting the incorporation of green lease clauses in leasing contracts. Green lease clauses incentivize tenants to work on improving environmental performance and to share data on the consumption of energy, water, and other resources, reduce the amount of waste generated in renovations, and use energy-efficient and environment-friendly equipment and materials.
We also promote green refurbishments that utilize green leases that contains a cost recovery clause. When carrying out green refurbishments, both the building owner and its tenants reap the benefits of reduced utility and other bills to realize a win-win relationship. For example, the owner receives a portion of the savings made on electricity bills through green refurbishments back as green lease payments for a certain period by incorporating a cost-recovery clause, thereby ensuring a fair distribution of the economic benefits of such refurbishments.
＜Kanazawa Park Building: Example of Installing LEDs Using a Green Lease Scheme＞
At the Kanazawa Park Building, the owner installed LED lighting at its own expense in tenant areas. The owner receives a portion of the savings made on electricity bills thanks to the installation as green lease payments for a certain period, thereby ensuring a fair distribution of the economic benefits of such refurbishments. Even if tenants make green lease payments, these can be more than offset through reductions in utility bills. Accordingly, both tenants and the owner enjoy economic benefits. In addition, we pay an incentive fee to the PM that acts as the contact point for negotiations with tenants, provides explanations on the scheme, and collects green lease fees. In these ways, we have established a win-win system for all three parties: tenants, the owner, and the PM company. With the owner recovering its investment and enhancing the value of its real estate, tenants reducing their electricity bills and improving their work environment, and the management company receiving fees, the installation of LED lighting at Kanazawa Park Building serves as an example of how to establish win-win relationships for all parties while enhancing property environmental performance through CO2 emissions reductions.

Collaboration with Suppliers
Green Procurement Policy
JRE-AM which is JRE’s asset management company, has set the Green Procurement Policy as one of the policies to implement the specific items upheld in the Sustainability Policy. The Green Procurement Policy provides guidelines on the selection of products to be procured by JRE-AM as well as on the selection and evaluation of suppliers. JRE-AM has been promoting sustainability measures across its supply chain based on this Policy.
PM company selection criteria and evaluation measures
JRE has established selection criteria for property management (PM) companies to which it commissions the management of properties, and evaluates all of the PM companies once a year, in principle. In addition to the companies’ building management and maintenance abilities, JRE evaluates the PM companies by their environmental friendliness in terms of operations, occupational health and safety measures for their employees, and understanding of and cooperation with the Sustainability Policy set by JRE-AM. Moreover, JRE requests the PM companies to make proposals to help JRE reduce environmental impacts, such as energy efficiency measures in buildings. In this way, JRE makes environmental improvement efforts in cooperation with the PM companies.
Other measures
JRE makes contracts with professional firms to conduct energy assessment of a selection of our properties, and utilizes the results to understand the current level of their energy performance and to formulate improvement plans for the future.
