Awareness of Climate Change
Since the Industrial Revolution, an increase in energy consumption has heightened the concentrations of greenhouse gases, such as carbon dioxide (CO2), in the atmosphere, and global warming is progressing. If warming continues without taking any effective countermeasures, there will be major changes in the earth's climate. This will cause phenomena such as rising sea levels and abnormal weather patterns, and have a great impact on the living environments of people and other organisms. Abnormal weather patterns will also increase the risk of damage to the business activities of the Mitsui Fudosan Group.
In order to curb global warming, reduce the risk to our Group due to climate change, protect environments where people and other organisms can live, and build a sustainable, low-carbon society, the Mitsui Fudosan Group believes that one of our key social missions as a real estate developer is to create, supply, and operate buildings and neighborhoods which curb energy consumption, and have low emissions of greenhouse gases.
Over the medium to long-term, we shall reduce energy consumption per base unit (of floor area) by an average of 1% every year.
On a per unit basis (of floor area), energy consumption in fiscal 2018 was 0.04199 ㎘ of oil equivalent/m2 per year, a reduction of 1.6% from the previous year.
(For details on energy consumption per base unit [of floor area], please see "Energy Consumption.")
*Goals:The primary greenhouse gas emitted by the Mitsui Fudosan Group is carbon dioxide (CO2) resulting from energy consumption. Therefore, no reduction goal has been set for greenhouse gas emissions, and our efforts are focused on the goal of reducing energy consumption.
Participation in Initiatives Concerning Adaptation to Climate Change
Participation in the United Nations Global Compact
The Mitsui Fudosan Group supports the UN Global Compact comprising 10 principles relating to human rights, labor, the environment, and anti-corruption advocated by the UN. We signed the compact in December 2018, and participate in the Global Compact Network Japan.
In 2001, our group established a Group Environmental Policy, and we have helped curb global warming by creating buildings and neighborhoods which conserve energy and have low greenhouse gas emissions, and we have also made efforts in areas such as prevention of environmental pollution, reduction of waste, and conservation of water and biodiversity. As a corporate group supporting offices, housing, and other infrastructure necessary for daily life, we will fulfill our social responsibility at an even higher level by making even greater efforts in the future in areas such as environmental conservation.

Energy Conservation, Creation, and Storage
In addition to energy conservation, the Mitsui Fudosan Group is actively engaged in energy creation using solar power and cogeneration systems, and energy storage using large-scale storage batteries. In this way, we create buildings and neighborhoods with low energy consumption and reduced emissions of greenhouse gases. We are also involved in energy-saving activities together with our business partners, tenant companies and stores, and customers.
Energy Conservation, Creation, and Storage in Office Buildings
Efforts at TOKYO MIDTOWN HIBIYA
At TOKYO MIDTOWN HIBIYA (Chiyoda-ku, Tokyo), we employ an exterior covering and high-performance glass to reduce thermal load, use high-efficiency systems and energy-saving equipment such as lighting control systems that utilize daylight, and make use of waste heat from a gas cogeneration system. We also create energy through the installation of a solar power system (generation capacity approx. 20 kW). By using these energy conservation and creation systems, we have attained Level 3 for Perimeter Annual Load (PAL) and Energy Reduction Ratio (ERR) evaluation in the Tokyo Metropolitan Building Environmental Planning System, and the S Rank in self-assessment under the CASBEE (Comprehensive Assessment System for Built Environment Efficiency) scheme.
We have also installed a new sub-plant for district heating and cooling (DHC), and by linking it with an existing DHC plant in the Hibiya area, we have helped realize a high-efficiency energy supply for the entire district.

Office Buildings in Tokyo Certified Again as Excellent Designated GHG Offices by the Tokyo Metropolitan Government
Since fiscal 2010, we have been acquiring and renewing certification for office buildings in the Tokyo metropolitan area based on the standards established by the Tokyo Metropolitan Government for Excellent Designated GHG Offices*.
At these office buildings, we are switching to energy-saving equipment, holding meetings to promote CO2 reduction, strengthening systems for collaboration with tenants, and promoting energy conservation activities.
As of March 31, 2019, Mitsui Fudosan has six office complexes (eight buildings) designated as Top Level Offices and eight office complexes (eleven buildings) as Semi-Top Level Offices under the Excellent Designated GHG Offices program.
*Tokyo Metropolitan Government’s Excellent Designated GHG Offices:The Tokyo Metropolitan Government uses 213 criteria for evaluating the impact of management systems, building equipment performance, and office building equipment operations on reducing CO2 emissions. Office buildings that receive this designation are singled out for their exceptional promotion of global warming countermeasures. The system alleviates liability for CO2 emissions, and has two ranks: Top Level Office (a score of at least 80 points) and Semi-Top Level Office (a score of at least 70 points).

*Note: Kasumigaseki Building and Tokyo Club Building are two buildings considered to be one office complex. Muromachi Higashi Mitsui Building, Muromachi Furukawa Mitsui Building, and Muromachi Chibagin Mitsui Building are three buildings considered to be one office complex.
Energy Conservation at Large-Scale Logistics Facilities
At our large-scale logistics facilities, Mitsui Fudosan Logistics Parks (MFLP), we are installing LED lighting and solar power systems.
Solar power panels at MFLP Inazawa (generation capacity approx. 1,500 kW)
Solar power panels at MFLP Ibaraki (generation capacity approx. 2,000 kW)
Energy Conservation at Mitsui Repark Parking Lots
Under the "Mitsui Repark" brand of Mitsui Fudosan Realty, we are creating next-generation parking lots based on the four key concepts of safety/security, innovation, environmental awareness, and disaster recovery assistance.
For instance, we have installed a hybrid solar system at the Mitsui Repark Minatomachi Niigata Parking Lot (Chuo-ku, Niigata City) which generates and stores solar power, and then illuminates the LED lighting of signage at night. Not only does the system reduce CO2 emissions, it also acts as an emergency power source in case of a disaster or power outage.

Greenhouse Gas Emissions
Greenhouse gases (GHG) emitted due to the business activities of Mitsui Fudosan (see Scope of Data Calculation) are primarily carbon dioxide (CO2) resulting from energy consumption. Aside from that, emitted chlorofluorocarbons (e.g., HFC) also fall under the same category.
GHG emissions at Mitsui Fudosan have been almost flat since fiscal 2016, and in fiscal 2018, the figure of 513,000 t-CO2 per year was almost the same as the previous year. However, GHG emissions per base unit (of floor area) were 0.08015 t-CO2/m2 per year, down 4.7% compared with the previous fiscal year.
Trends in the Amount of GHG Emissions
Note: Calculation of CO2 emissions is done based on the Manual for Calculation and Reporting of Greenhouse Gas Emissions (Ministry of the Environment; Ministry of Economy, Trade and Industry). In calculating CO2 emissions for each fiscal year, we use the definitive values of CO2 emissions coefficients for electric power use in each previous fiscal year.
