Basic policy
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
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.
| 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.
| FY2023 | FY2024 | |
| CC1 | 2.16 | 2.02 |
| CC2 | 2.03 | 1.96 |
| CC3 | - | 2.65*3 |
*1Water Usage Effectiveness (WUE): The annual water usage in data centers divided by the energy consumption of IT equipment.
*2Power Usage Effectiveness (PUE): The annual power consumption in data centers divided by the energy consumption of IT equipment.
*3Calculated using data from July 2024 to March 2025.
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.
| FY2023 | FY2024 | ||
| Childcare leave adoption rate* | Male | 85.7% | 100% |
| Female | 100% | 100% | |
| Average number of paid leave days taken | - | 14.3days | 14.4days |
*Calculated using a method defined by the Ministry of Health, Labour and Welfare, which includes employees who gave birth more than two fiscal years ago and took childcare leave in the previous fiscal year.
Comprehensive training system
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.

As a company that supports social infrastructure, we have established and maintained a ‘Business Continuity Management’ (BCM) system to protect human life and safety and minimize the impact on society in the event of a natural disaster, such as an earthquake, volcanic eruption, or any other crisis that could significantly disrupt our operations.
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.
