We endeavor to preserve and restore the global environment, reduce our environmental impact through our business and social contribution activities, and contribute to the realization of a society that can develop sustainably.

1. 1.Response to climate change

   We are promoting a modal shift toward public transit as a corporate group engaged in environmentally friendly public transportation. At the same time, we aim to realize carbon neutrality through energy conservation, energy creation, and renewable energy initiatives.

2. 2.Promotion of a recycling-based society

   We endeavor to promote a recycling-based society through the effective use of resources and energy, as well as initiatives to reduce, reuse, and recycle waste.

3. 3.Preservation and restoration of nature and biodiversity

   We endeavor to preserve and restore the rich nature and biodiversity along our railway lines so that the next generation can inherit a better environment surrounding the railway.

4. 4.Communication with stakeholders

   We communicate with our diverse stakeholders through engagement activities and information disclosure with the aim of cooperating and working together with local communities.

5. 5.Promotion of awareness-raising and educational activities for executives and employees

   We engage in ongoing awareness-raising and educational activities through internal training and other initiatives with the aim of enhancing environmental awareness among our executives and employees.

6. 6.Compliance with environmental laws

   We adhere to environmental laws and international standards as we pursue our business activities.

Group companies, including Keikyu Corporation, conduct business activities in compliance with environmental laws and regulations established by the government and municipal authorities and submit plans and reports as required. In addition, the Inquiry and Auditing Group Operating Department conducts regular audits that include inspections of documentation and the status of execution of waste-related contracts. In fiscal 2024, there were no violations committed by the Company or Keikyu Group companies.

With the aim of helping to realize a carbon-neutral society, we have established long-term environmental targets. We will advance and appropriately monitor initiatives to reduce GHG emissions.

We have positioned ESG initiatives as the basis of business management and pursue sustainability measures including climate change countermeasures as a matter of management strategy. In addition, we conducted analysis and disclosure based on the TCFD recommendations in June 2022 with the aim of helping to realize a carbon-neutral society. We will continue moving forward with climate change countermeasures while further increasing analysis and disclosure.

By fiscal 2010, we had discontinued all traditional resistance-controlled railcars and replaced them with energy-saving railcars equipped with regenerative brakes. In addition, we have progressively introduced variable voltage variable frequency (VVVF)-controlled railcars, which are more efficient in regenerating electricity than field chopper-controlled railcars. As of the end of fiscal 2025, VVVF-controlled railcars accounted for approximately 100% of our railcars.

For use in the operation of facilities, we have introduced solar power generation to some of our railway stations and Group companies.

Changeover to renewable energy

Keikyu Corporation
• Electricity consumption of the operations of the Airport Line (since 2021)
• Electricity consumption of the business operations of 19 railways stations on the Keikyu Main Line between Keikyū Higashi-kanagawa and Kanazawa-hakkei Stations and all railway stations on the Zushi Line (since 2021)
• Electricity consumption of the Keikyu Group head office, which includes the offices of 12 Group companies (since 2021)
• Electricity consumption of the business operations* of six railway stations on the Kurihama Line between Keikyū Kurihama and Misakiguchi Stations (since June 2023)

Group companies
• Electricity consumption of Hayama Marina (since April 2023)
• Electricity consumption of certain real estate properties owned by Rinko Estate Co., Ltd. (since April 2023)

The aforementioned introduction of electricity generated from renewable energy sources reduces CO₂ emissions by an amount equivalent to approximately 12,000 tons per year.

• *Railway station lighting, air conditioners, railway station equipment, railway crossings, and signals

In an effort to minimize environmental impact, Keihin Kyuko Bus Co., Ltd., has been operating SORA fuel cell buses and compact electric buses, which were introduced in 2019 and March 2023, respectively. Meanwhile, Kawasaki Tsurumi Rinko Bus Co., Ltd., has been working to reduce the burden on the environment by operating buses that use biodiesel fuel.

To promote a recycling-based society, we are making effective use of finite resources and reducing waste. As a corporate group with rich marine environments in our lineside areas, we are also actively advancing initiatives to reduce ocean plastic waste.

In March 2019, Kawasaki Tsurumi Rinko Bus concluded an agreement with the city of Kawasaki for the use of water that has undergone advanced treatment at the Iriezaki Wastewater Treatment Center. By washing buses with water produced from the advanced treatment of sewage, we will utilize water resources effectively and help build a society based on recycling and consideration for the global environment.

In 2019, we concluded an agreement with Kanagawa Prefecture on cooperation and collaboration for the promotion of the SDGs. As part of this initiative, we are promoting the Keikyu Group Plastic Waste Reduction Campaign, which is focused on reducing ocean plastic waste. Aiming to help realize SDG 14, which calls on humankind to “Conserve and sustainably use the oceans, seas and marine resources for sustainable development,” the Keikyu Group is implementing a range of activities, such as conducting cleanup activities at beaches, popularizing reusable shopping bags, and introducing straws made of biodegradable materials, throughout the Group.

We contribute to the conservation of biodiversity through activities to preserve the natural environment in lineside areas and through
environmentally friendly business activities.

Launched in February 2023, the Miura Forest Project aims to further demonstrate the capacity of these forests to absorb carbon dioxide through the sound management of the approximately 100 hectares of Company-owned forests in the Miura Peninsula, as well as create beautiful and highly functional forests that help preserve biodiversity and open up possibilities for the future.

One of Miura’s irreplaceable assets, Koajiro Forest still has a natural water system as well as a valuable ecosystem that is home to rare species. As part of our cooperation in efforts to protect the natural environment, we have voluntarily preserved roughly 10 hectares of our forest and donated approximately 2 hectares to Kanagawa Prefecture in response to its designation of Koajiro as a special suburban green space preservation area.

We have positioned ESG initiatives as the basis of business management and pursue sustainability measures including biodiversity conservation as a matter of management strategy. We have become an adopter of the TNFD since June 2025, and have been progressively analyzing and disclosing the impact of our group’s business activities on natural capital.
In June 2026, we made comprehensive disclosures, and we will continue to further strengthen our initiatives regarding natural capital as an integral part of our business strategy.
