Environmental management

The Keikyu Group Basic Environmental Policy

We endeavor to preserve 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.

Action Guidelines

  • We endeavor to make further improvements to convenience and to create appealing value along our railways, with a focus on providing environmentally friendly public transportation.
  • We endeavor to reduce our impact on the environment through the effective use of resources and energy, as well as initiatives to reduce, reuse, and recycle waste.
  • We endeavor to coexist with and preserve the rich natural environment along our railway lines so that our children, who will lead the next generation, inherit a better environment surrounding the railway.
  • We place value on communication with all of our stakeholders, and endeavor to cooperate and work together with local communities.
  • We endeavor to correctly comprehend and comply with environmental laws and regulations and to improve the environmental awareness of all of our employees through awareness campaigns and educational activities.

Endorsement of Task Force on Climate-related Financial Disclosures (TCFD) Recommendations

ESG initiatives, in our view, form the foundation of business management. Accordingly, we have established key performance indicators (KPIs) with the aim of curbing the greenhouse gas (GHG) emissions generated by our business activities. In addition, on November 11, 2021, Keikyu announced its endorsement of the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), established by the Financial Stability Board with a view to realizing a carbon-free society. Going forward, we will disclose climate-related financial information in accordance with TCFD recommendations.

Environmental data

Environmental burden data, environmental accounting

Environmental burden data (FY2020)

Energy and resources are essential for the operation of railways and the conduct of business activities, and these activities produce waste, including CO2 and other substances that cause global warming. The Keikyu Group quantitatively analyzes and strives to reduce the environmental impact of its business activities.

Nonconsolidated environmental accounting

Environmental accounting is a system for recognizing the costs incurred as a result of environmental preservation activities as well as the effects of such activities. Environmental accounting also provides a framework for measuring and communicating this information as quantitatively as possible.
We have been using environmental accounting since fiscal 2008.

Environmental initiatives

Efficient use of resources and energy (realization of a low-carbon society)

Promoting the introduction of energy-saving vehicles

By FY2010, all of our trains adopted regenerative brakes to improve energy efficiency. Electricity generated when brakes are applied on a train is fed back to the overhead lines, to power other trains.

Initiatives to Reduce Our Environmental Footprint

Our railway operations are introducing new, outstanding energy-saving railcars. By 2010, we had discontinued traditional resistance-control railcars, and all of our railcars had been equipped with energy-saving regenerative brakes.
In 1990, we began using a variable voltage variable frequency (VVVF) control system, which is more efficient in regenerating electricity than a field chopper control system. The aforementioned initiatives have reduced electricity consumption by about 30.0%.
