Initiatives for the Environment
Basic Policy on Environment
We will actively address environmental issues and aim to balance between a rich environment in the future and business activities.
Responding to Climate Change
Keihanshin Building recognizes that the climate change problem brings about dramatic changes to the natural environment and social structure, and that it is a key issue (materiality) that has an impact on our Company's overall management and business. Based on this recognition, we evaluate the impact of long-term and highly uncertain climate change on our business, and respond appropriately to medium- to long-term changes including the transition toward a decarbonized society and physical impacts such as climate change and rising sea levels, by building the corporate structure, enhancing the efficiency of energy use, reducing greenhouse gas emissions, and other means.

Information Disclosure Based on TCFD Recommendations
In November 2021, the Company announced its endorsement of the Task Force on Climate-related Financial Disclosures (TCFD). Taking this opportunity, the Company is assessing the impact of climate change on its business, and from June 2022, has been disclosing climate change-related information in line with the framework recommended by the TCFD.
In view of the need to enhance information disclosure on the financial impact that climate change and other sustainability issues have on a company, which enables investors to make appropriate investment decisions, the Company recognizes anew that initiatives to address climate change and other sustainability issues will contribute to the medium- to long-term enhancement of its corporate value.

Sustainable Use of Resources and Contribution to Recycle-oriented Society
We will strive to make effective use of limited resources through prolonging the lives of buildings, reducing waste, conserving water or other methods, thereby contributing to the realization of a recycle-oriented society.
Indicators and Targets
GHG emissions
KPI: Reduce GHG emissions (Scope 1 and 2) by 46% by FYE March 2031 (compared
to the FYE March 2020)
Achieve net-zero emissions by FYE March 2051
In the fiscal year ended March 31, 2024, Scope 3 GHG emissions accounted for about 96% of the Company's total supply chain GHG emissions. Of Scope 3 GHG emissions, approximately 88% are GHG emitted by the business activities of tenants (customers) of our leasing properties (Category 13), and approximately 85% of the Company's total supply chain GHG emissions consists of those emitted by the business activities of tenants (customers) of our leasing properties. This distinctive figure is due to the fact that we lease datacenter buildings.
Compared to office buildings, datacenter buildings use a larger amount of electricity to operate and cool IT equipment. However, we believe that we are making a certain contribution to energy conservation and GHG emissions reduction in society as a whole through efforts such as having datacenter users transfer and consolidate their servers and other IT equipment scattered across multiple locations into a state-of-the-art datacenter building with high energy efficiency.
We believe that in order to reduce GHG emissions across the entire Company, it is essential to promote energy conservation initiatives in cooperation with tenants (customers) and encourage them to consider the use of renewable energy. We will continue to work to reduce GHG emissions in cooperation with tenants (customers).
- ※Prior year results have been revised due to a review of the findings of a third-party verification
organization. Regarding lighting and air conditioning power in some office tenant-only areas,
which was previously calculated as Scope 2, It was pointed out that this is electricity usage by
tenants (customers) and should be classified as Scope 3. Therefore, we have revised the
classification between scopes.
※Figures with check marks have been verified by a third-party organization.
※Calculations were made according to GHG protocol standards.
※Scope 1 and Scope 2 are calculated using emission factors and other methods in line with the
Act on Promotion of Global Warming Countermeasures, based on the amount of energy used
(whether actual figures or estimates) in the relevant fiscal year.
Energy usage
KPI: Reduce per-unit energy consumption by 10% (compared to FY2019) by FY2030
through energy-saving efforts.
- ※ Figures are totals for Scope1 and 2, and do not include properties being leased as a whole
building to a single tenant. Total target floor area is calculated based on the occupancy rate.
Use of renewable energy
KPI: 100% of the electricity used by the Company under Scope 2 shall come from
renewable energy sources by FYE March 2051.
To reduce GHG emissions associated with energy consumption, in addition to promoting energy-saving measures, the Company is also working to introduce power from renewable energy sources. Since the fiscal year ended March 2024, some of the Company's properties have switched to using electricity from renewable energy sources.
- ※Applies only to electricity consumption for Scope 2.
We are also working with tenants (customers) on Scope 3 to reduce GHG emissions, and solar panels are installed on the rooftop of Keihanshin Fuchu Building.

Ratio of properties with green building certifications by total floor space
KPI: Raise the ratio of the area of properties with the Green Building Certification to
50% or more by FY2030 and acquire the Green Building Certification for all newly
constructed properties in the future.
We promote the acquisition of green building certifications, such as CASBEE Real Estate Certification and BELS Certification, in order to objectively assess the condition of our buildings through external evaluations, and at the same time, to use them as a reference for further improvement and enhancement.
Overview of CASBEE Real Estate Certification
The CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) is a method for rating the environmental performance of buildings. The method comprehensively assesses building quality, including interior comfort and attention to the surrounding scenery, in addition to care for the environment (such as use of materials and equipment that conserve energy with a minimal environmental impact). For more information on CASBEE, please see the link below.
CASBEE Real Estate Certification assessment ranking
The CASBEE Real Estate Certifications we have obtained are as follows:

Of net sales of 19.3 billion yen for the fiscal year ended March 31, 2024, net sales from nine properties with green building certifications are 7.0 billion yen, accounting for approximately 36% of total net sales.
Initiatives to realize a recycle-oriented society
Prolonging the lives of buildings and improving durability
The Company strives to prolong the service life of buildings by adopting long-life, high-durability materials and appropriately managing and repairing buildings based on the idea of "preventive maintenance," in an effort to conserve limited resources and reduce the volume of waste. By making improvements in the interior, facilities, the building structure, and other parts, we enable buildings that have been in service for many years, such as the Kawaramachi Building that houses the Company's Head Office, to offer greater convenience and comfort. This has led tenants to use them for many years.
Working with customers to reduce and recycle waste
In cooperation with our cleaning partner companies, we have been asking customers to work
with us for the separation and recycling of waste. We have placed waste sorting boxes on tenant floors with the cooperation of customers, and work together with them to reduce and recycle waste.
Reducing paper consumption at our offices
The Company has been working to reduce the amount of paper used in the its offices by digitalizing operations and adopting paperless work processes.
Appropriate management of hazardous waste
For asbestos, PCB, CFCs and other hazardous wastes, we conduct surveys and dispose of
them appropriately in accordance with relevant laws and regulations.
High energy conservation performance （example of the Toranomon Building）
The Toranomon Building uses airflow windows※*, a zoned air conditioning system, and LED lighting for system ceilings. The building contributes to reducing the burden on the environment with its high-spec energy-conservation performance, such as automatic light adjustment by sensors.
- Airflow is directed between an outer and an inner layer of glass, mitigating the afternoon sun in summer and the cold in winter, and achieving both comfort and energy conservation.

To reduce water usage and the volume of waste
Keihanshin Building considers the appropriate use of limited resources important for protecting the environment and local communities and contributing to the realization of a recycling-oriented society, and it is also essential for the sustainable growth of the Company. Based on this recognition, we have formulated policies aimed at reducing water consumption and the volume of waste generated, and are working on water conservation and waste reduction.
