Initiatives implemented by the Group companies
Greenhouse gas reduction
Utilizing energy-saving rail cars and equipment
All of the Group's railway companies aim to reduce their environmental burden by improving transportation efficiency. To that end, they have been upgrading to energy-saving rail cars and installing energy-efficient facilities at train stations in an effort to cut down on energy consumption.
- Seibu Railway Progressively replacing express trains on the Seibu Ikebukuro Line with new highly energy-efficient Laview model express trains
- Seibu Railway Introduced trains with energy-saving 40000-series models equipped with state-of-the-art motors to reduce electricity consumption by 40% compared with previous models
- Seibu Railway Installed regenerative braking systems to more efficiently restart after braking, and equipped train stations with backup power supplies
- Seibu Railway Installed LED lighting in train stations
- Seibu Bus, Izuhakone Bus, Izuhakone Taxi Group, Ohmi Railway, and Ohmi Taxi Introduced hybrid vehicles to bus and taxi fleets
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.
- Seibu Railway, Prince Hotels, and Ohmi Railway Operating nine solar power plants nationwide that generate about 22 million kilowatts annually
- Prince Hotels Operating a hydroelectric plant in the city of Karuizawa that generates 1.48 million kilowatts annually
- Operating air-conditioning systems using geothermal energy at the Hakone Yunohana Prince Hotel and Manza Prince Hotel, reducing CO2 emissions by 2,470 tonnes annually
- Seibu Construction Researching applications of small-scale and micro hydroelectric power generation to use water resources on Group-owned land and at plants
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.
Reducing waste from operations
The Group companies have been carrying out various initiatives for minimizing trash and controlling waste, such as promoting a shift to paperless operations by using information and communications technology (ICT) to reduce waste at offices and workplaces. Moreover, Prince Hotels has been taking steps to reduce, process, and recycle food waste at hotels.
- Prince Hotels Cutting food loss by improving purchasing policies, displaying posters to educate staff and guests about leftover food, and reducing meal portions
- Prince Hotels Reusing spoiled and leftover food as fertilizer
- Digitizing and reducing paper documents and records to cut down on paper consumption and to control waste
Promoting recycling and reuse
Seibu Railway and Seibu Bus have been supplying other companies with decommissioned trains, used buses, and usable equipment to ensure their reuse and reduce the environmental burden related to their dismantling and disposal. The Group companies also make use of wood from thinning the forests that they manage, including a forest in the city of Hanno, Saitama Prefecture.
- Seibu Railway, Seibu Bus, and Ohmi Taxi Supplied other companies with decommissioned trains, used buses and taxis (after maintenance and inspection), and used signaling equipment
- Seibu Railway and hotels in Hawaii Used wood from forest thinning to make benches and wood chips.(Click here for Seibu Railway's environmental initiatives.)

- Seibu Landscape Established a technique for composting plant-based waste
- Ohmi Railway Became Japan's first private-sector bus operator to use biodiesel made from vegetable oil and light oil
Ensuring water supply
Taking steps to limit water consumption
To help conserve precious water resources, The Group companies have created policies for limiting water consumption and installed equipment for reusing rain and wastewater.
- Prince Hotels Reusing wastewater and rainwater

Implementing measures for maintaining a clean water supply
The Group is actively involved in preventing water pollution. For example, Prince Hotels makes donations to municipalities that possess reservoirs in order to help them maintain good water quality. Meanwhile, Seibu Construction and Seibu Landscape both implement measures for preventing the discharge of wastewater from their construction work.
- Prince Hotels Donating one yen for every bottle of local spring water sold to the city of Minami-Uonuma, Niigata Prefecture(details included in the Prince Hotels news release)
- Seibu Construction Building barriers with bentonite clay in landfills to prevent waste from contaminating the groundwater
- Seibu Landscape Using backing soda instead of herbicides when weeding eliminates the discharge of herbicides into nearby bodies of water and rivers
Protecting forest and species
Proactively preserving forests
The Group companies have been cooperating with the municipalities they operate in to protect forests and green spaces, and companies that have forests on their properties make proactive efforts to conserve them.
