AT TOKYO’s initiatives to achieve sustainability

President’s message

President & Chief Executive Officer
Tatsuya Izumida

As a data center company, AT TOKYO has been diligent in ensuring the safety and peace of mind of our customers’ businesses based on the core principle of zero-downtime operations. We operate a wide range of equipment that consumes significant amounts of energy, which is why we are deeply committed to environmental responsibility. To maintain the high level of service that we offer, we prioritize the safety and health of all our employees, fostering a work environment that supports both their physical and mental well-being. AT TOKYO will continue to advance initiatives focused on ESG (Environment, Social, and Governance).

Our basic policy and progress

AT TOKYO is committed to being part of a sustainable society in line with the ‘SECOM Group Basic Sustainability Policy’*1. Our efforts have been recognized by EcoVadis, an international CSR rating agency based in France, which has awarded AT TOKYO the prestigious ‘Platinum’ rating for the second consecutive year, following the 2023 survey*2. This rating is only granted to companies that are ranked in the top 1% of those assessed globally, reflecting the high quality of their sustainability management systems. In addition, we obtained ISO 45001 certification in 2023, and are dedicated to creating a comfortable work environment that promotes the physical and mental well-being of our employees. We remain focused on further strengthening our efforts to address sustainability challenges.

Environment

Basic policy

Communications traffic and power consumption continue to rise with rapid advancements in digitalization, and so data center companies and their users are required to take even more proactive measures in order to achieve a sustainable and decarbonized society.
The SECOM Group has committed to the ‘SECOM Group Carbon Zero 2045’ initiative*1, aiming to achieve net-zero greenhouse gas emissions by 2045 for Scope 1 and 2 emissions across the entire group, with an interim goal of a 45% reduction in emissions by FY2030, compared to FY2018 levels (SBT certified). AT TOKYO, as a member of the group, will advance initiatives to achieve decarbonization targets. We also promote sustainable practices in procurement, waste reduction, and resource recycling, in alignment with the SECOM Group Environmental Policy.
Through these efforts, we aim to contribute to a sustainable, decarbonized, and environmentally friendly society.

Initiatives to reduce greenhouse gas emissions

Commitment to renewable energy

The SECOM Group has joined RE100 and is committed to ensuring that 100% of the electricity used in its business activities comes from renewable energy by 2045. To achieve this goal, we are actively promoting the use of renewable energy across our operations. Since April 2024, the source of electricity used by our data centers in Tokyo has been classified as renewable energy through the acquisition of FIT non-fossil certificates as standard*1. In addition, we have signed an off-site physical corporate power purchase agreement (PPA), through which a portion of the electricity used at AT TOKYO’s Data Center #3 (DC3) is directly supplied by green power.

Greenhouse gas emissions

In FY2024, AT TOKYO’s greenhouse gas emissions totaled 448.94 t-CO2 for Scope 1, and 13,079.54 t-CO2 for Scope 2 (based on market standards). To further reduce carbon emissions for companies utilizing our data centers, we will continue to pursue a range of sustainability initiatives.

Initiatives for effective use of water resources

Reuse of boiler blowdown water

We are committed to reducing water consumption by reusing cooling water (blowdown water) used to dissipate heat generated in data center server rooms. In FY2024, we successfully reused a total of 39,860m3 of cooling water that would otherwise have been disposed of.

Blowdown water reuse rate in FY2024
CC1 CC2 Total
Blowdown water 57,354㎥ 70,099㎥ 127,453㎥
Recycled water 19,690㎥ 20,170㎥ 39,860㎥
Reuse rate 34.3% 28.8% 31.3%

Promoting water conservation

In addition to installing automatic faucets in the restrooms at all our centers in Tokyo, we have implemented waterless toilets at AT TOKYO Chuo Center #2 (CC2). At AT TOKYO Chuo Center #3 (CC3), we have introduced water-saving taps and flush tank toilets designed to conserve water. Furthermore, CC3 uses a sealed cooling water system for air conditioning, which significantly reduces evaporation into the atmosphere, resulting in substantial water savings.

Management of WUE

Since FY2022, we have been tracking and managing WUE*1for each data center. While evaluating the absolute value of WUE is challenging due to significant variations in water usage based on the method of heat source, we continue to monitor these metrics and assess their performance by comparing it with historical data or PUE*2.

Social

Basic policy

We are dedicated to fostering a work environment where everyone feels motivated and supported. We promote a healthy work-life balance, enhance our training systems, and facilitate remote work options to ensure a positive and flexible workplace.
We are also accelerating initiatives to promote diversity in our workforce, offering flexible work styles to accommodate diverse needs.
In addition, we prioritize Occupational Safety and Health initiatives by obtaining ISO 45001 certification and conducting regular safety patrols. These initiatives help instill a culture that values the safety and well-being of both our employees and partner companies, creating a workplace where everyone can work comfortably and in good health.

Diversity and human resources development

Support for work-life balance

To create a comfortable and supportive work environment, we have established a childcare leave system that can be utilized until a child turns three years old, along with a shortened work-hour system available until the child completes their third year of elementary school. We also offer individual support for expecting parents, including personal interviews and the creation of an in-house handbook.
Additionally, we have introduced a leave system and financial subsidies for infertility treatments, and in 2023, we held a seminar to raise awareness and deepen understanding within the workplace.
Furthermore, we actively encourage our employees to take advantage of the various types of leave available to them.

Comprehensive training system

We offer numerous opportunities for employees to develop diverse skills, helping them expand their knowledge and capabilities as professionals. This approach allows us to integrate diverse values and talents, ultimately enhancing our collective performance as a team.

Facilitating remote work

As part of our efforts to promote work-life balance, we have introduced a remote work system that allows employees to choose their preferred work location. They can now work from home, their hometown, or while traveling.

We conduct risk analysis related to business continuity twice a year. For identified risks, we develop preventive and mitigation measures, along with detailed responses (BCP: Business Continuity Plan) to restore and maintain business operations.
Additionally, we hold company-wide BCP training once a year to ensure its effective implementation.
