Greenhouse gas reduction

Utilizing energy-saving rail cars and equipment

All of the Group's transportation companies aim to reduce their environmental impact by improving transportation efficiency. To that end, they have been upgrading to energy-saving rail cars and installing energy-efficient facilities at train stations and will continue to carry out research on train, bus, and taxi driving technologies in an effort to cut down on energy consumption.

Specific initiatives

Proactively utilizing renewable energy

Various group companies are working to reduce their energy consumption by using electricity supplied from renewable energy sources, such as solar power plants, and utilizing geothermal heating and cooling systems. Moreover, Seibu Construction has been researching applications of small-scale and micro hydroelectric power generation as a means for reducing emissions of greenhouse gases.

Specific initiatives

Improving energy conservation at offices and plants

The Group companies have been making buildings more energy efficient by installing various types of equipment, including highly efficient heating systems and LED lighting. Newly constructed office buildings, especially, are designed with the latest energy-conserving technologies. In recognition of these efforts, the Association for Housing Performance Evaluation & Labeling, Japan's leading building assessment association certified Tokyo Garden Terrace Kioicho with the highest rating, five stars, under their Building and Housing Energy-Efficiency Labeling System.
