Coexistence with the environment

Initiatives to reduce CO2 emissions

We are working to reduce electricity consumption in the office by promoting measures such as improving air conditioning efficiency by keeping blinds closed during the summer, turning off all lights in the office at a set time after work and turning on only lights in necessary areas, consolidating servers in highly energy-efficient data centers, expanding the use of public clouds, setting energy-saving settings for office equipment, and promoting a dress code-free policy that allows employees to wear clothes according to the working environment and occasion, including the season and temperature.We are also introducing a "telework system" for all employees, setting up satellite offices, and utilizing shared office services, which not only reduces energy consumption by reducing the use of public transportation for travel, but also reduces paper usage by digitizing documents, thereby contributing to reducing environmental impact.
Furthermore, our head office (Shinagawa Season Terrace), Kansai Branch (Osaka) (Grand Front Osaka), Nagoya branch (Chunichin Building), and Kyoto sales office (KDX Karasuma Building) use electricity generated from renewable energy sources installed in the buildings they are located in. *Employee coverage rate for renewable energy use at business locations: 95.0% (as of April 30, 2025)

Reduction of waste generation

In addition to providing a centralized space for the company to share and manage stationery, documents, envelopes, etc., we have stocked stationery mainly with refills, and are promoting the reduction of the use of office paper and the thorough reduction and separation of waste generated from the office. In addition, we are working to reduce waste by requesting a specialized recycling company to take over furniture and fixtures during renovation work at each base, and further promoting the recycling of equipment used on-site, such as workwear, helmets, and safety belts.

Reducing resource use

We aim to reduce our environmental impact by actively promoting the effective use and reuse of resources. We have set up a centralized space for the company to share and manage stationery, documents, envelopes, etc., and we maintain a stock of stationery, mainly refills. As part of our resource utilization management, we monitor the amount of office paper used and strive to reduce paper usage compared to the previous year. We are making progress in digitizing the circulation of forms, reducing paper output by promoting online meetings, and digitizing documents. Paper usage in fiscal 2024 (*) was 2,503,500 sheets (fiscal 2023: 2,732,500 sheets).

Effective use of water resources

We are committed to making improvements in light of the importance of making effective use of water resources in our business activities. Shinagawa Season Terrace, where Tanseisha's head office is located, is located above the Shibaura Water Reclamation Center, and in addition to conserving water and utilizing recycled water, we also make maximum use of the sewage heat and reclaimed water generated at the center. In addition to utilizing the stable sewage heat as a heat source, we also use the reclaimed water for flushing toilets and watering plants.
