Environmental Management System

Basic Approach to the Environment

ID&E established the Ten Environmental Principles striving to reduce the environmental load and effectively utilize resources through business and to encourage each employee to think and act on their own.
We use a quality and environmental management system that practices these environmental principles in business and the ID&E expertise and knowledge about environmental conservation to help preserve the environment according to the SDGs that aim to realize a sustainable world.

    Proactively engage in environmental impact assessment.
  • 5.
    Pay attention to the diversity of environmental fields.
  • 6.
    Enhance technological capabilities with environmental consideration as a value added.
  • 7.
    Consider cost effectiveness in relation to environmental considerations.
  • 8.
    Propose measures and processes enabling environmental considerations.
  • 9.
    Accumulate, share and communicate knowledge and information relating to environmental considerations.

    Incorporate environmental considerations into quality management system.

Quality and Environmental Management System

Nippon Koei has built and operates a quality and environmental management system at each business headquarters in compliance with ISO 9001 and ISO 14001 standards in an active effort to ensure quality and protect the environment in its business activities.
This quality and environmental management system standardizes business processes and fosters ongoing improvements by setting and pursuing quality and environmental objectives as well as assessing the effectiveness of the system.
By operating this system and responding to quality and environmental risks and opportunities that affect our business activities, we are working to improve quality and customer satisfaction and fulfill our social responsibilities through environmental considerations.

Operational Flow of the Quality and Environmental Management System

Contributing to the environment through business

We have been involved in many environment-related projects in the consulting business. In our business model centering on consulting, the direct environmental load on our business is limited but supporting customers' environmental efforts makes it possible to indirectly contribute to the environment, contributing to the improvement of the global environment through our business. In power and energy related businesses, we are also involved in the operation of hydroelectric power plants independently, contributing to the spread of renewable energy.

Water Resources

We are developing a water and sewage network to supply and treat water safely and stably and developing dams that are useful for utilizing water resources and preventing flood damage. In the fiscal year ended June 30, 2020, we started 16 new projects in countries including Indonesia, Nepal, and India.

Modal Shift Promotion

In order to eliminate trafc congestion and air pollution in areas where urbanization is progressing rapidly, each country is working to improve their urban public transportation networks. In the scal year ended June 30, 2020, we started 12 new projects in countries including India, the Philippines, and Bangladesh, contributing to the reduction of CO2 emissions and the improvement of people's quality of life.

Environmental Data

CO2 emissions are decreasing due to the promotion of energy-saving activities at offices and factories and the use of solar power generation at factories.
In addition to curbing energy consumption, we are working to supply 100% renewable electricity from the hydroelectric power plants that we operate to three of our company locations (Head Office, R&D Center, and a manufacturing site).


We carry out planning and studies for biodiversity and ecosystem conservation. In the fiscal year ended June 30, 2020, we started new projects in countries including Myanmar, Vietnam, and Iran.

Development of Clean Energy

We provide consulting and management systems for the introduction of clean energy, including hydraulic power and solar power in Japan and overseas. In addition, we are independently engaged in a small-scale hydropower generation business and currently own eight power plants. In the fiscal year ended June 30, 2020, the amount of power generated was 14,918,000 kWh, which is equivalent to a CO2 reduction of 7,117 tons.

Waste Treatment

We formulate plans and conduct studies for proper waste management and treatment. In the fiscal year ended June 30, 2020, we started new projects in countries including Myanmar, Mozambique, and Dominica.
