Responding to Climate Change

Approach to Climate Change

Solving the problem of global warming caused by greenhouse gases is an urgent issue for all of us living on this planet.

We provide a consulting service to reduce greenhouse gas emissions of our customers in a wide range of business fields. For example, Nippon Koei promotes the modal shift from automobiles to railroads and ships, supports conversion to renewable energy (hydraulic, solar, wind, and biomass), supports the efficient use of energy through ESCO (Energy Service Company) services, and contributes to a variety of fields, such as controlling greenhouse gas emissions by improving waste treatment technology and supporting the CDM (Clean Development Mechanism) business.

In the area of research and development, we have set "develop technology for responding to climate change" as one of the main technology measures that we are implementing across the entire company since the fiscal year ended June 30, 2016, and are working on the development of related cutting-edge technology and new businesses.

Also, since responding to climate change is an issue common to all of us, we are also working to widely share and disseminate our related know-how.

In addition to the existing framework, we will strongly promote new fusion of internal and external technologies and knowledge, and actively contribute to the realization of a low-carbon society by actively utilizing open innovation.

Specific Initiatives

Support and Participation in the “Challenge Zero”

Nippon Koei supports the “Challenge Zero” Declaration, which acts as a cooperative initiative to combat climate change between the Keidanren and Japanese government.

Challenge Zero actively communicates and advocates further innovative action by companies and associations worldwide to realize the decarbonized society positioned as a long-term goal in the Paris Agreement, an international framework of climate change countermeasures.

Contributing to the decarbonization of Yangon

Contributing to the decarbonization of Yangon

Our company was selected by the Ministry of the Environment of Japan for the 2020 City-to-City Collaboration for Low-Carbon Society, and with Fukuoka City as our partner, we are conducting the Green Recovery Promotion Project for Optimal Urban Transportation and Environment Creation to reduce CO2 emissions in our sister city, Yangon (located in Myanmar).

In Yangon, waste is increasing and inefficient waste collection and transportation operations are becoming an issue. In this project, quantum computing and AI technologies provided by Groove Notes Inc. will be used to improve the efficiency of worker shifts, work planning, and transportation routes. The project aims to formulate a city-level waste strategy and develop a collection and transportation system while taking into account safety, energy efficiency, and environmental protection.

Small-scale Hydropower Generation Initiatives

Small-scale Hydropower Generation Initiatives

The history of small-scale hydropower generation at Nippon Koei stretches back to the end of the Taisho Period. Before the war, our founder Yutaka Kubota and a group of engineers visited a hydropower business on the Yalu River flowing on the border between Korea and China. At the time, our company was involved in a variety of power supply development businesses including the Suiho Dam and Supung Hydropower Station (60,000 kW) on the Yalu River, known as the largest dam in the world. We carry on this history even today by engaging in all aspects of the power business from power generation to supply, such as the manufacture of water mills, power generators, central monitoring and control systems as well as dam management systems founded in the planning, design and supervision of project construction whether dams and other waterway facilities, power transmission and distribution facilities, or power distribution systems. Our efforts in hydropower generation formalized as a business in the 2010s with emphasis on popularizing renewable energy.

One of these hydroelectric power generation businesses is the Suidoyama hydroelectric power plant (Koriyama City, Fukushima) that started operations in March 2020. This power plant features small-scale hydropower generation for effective use at an existing waterworks facility. The system incorporates a power generation mechanism that uses the altitude difference to transport water taken from Inawashiro Lake to use as tap water to the water purification plant. This is the first public-private venture in Koriyama City. The project has been highlighted as a business that effectively takes advantage of unused energy while producing clean energy.

This project aims to revitalize the climate change adaptation business by conducting a survey and examination on the possibility of Japan's contribution to climate change adaptation business in developing countries and the ideal way for Japan to go about efforts in the field of climate change adaptation. In December 2019, we held a climate change adaptation business seminar to share information with private companies about business opportunities related to climate change adaptation. At COP25, we have also held side events such as panel discussion relate to climate change adaptation cohosted by the Ministry of Economy, Trade and Industry.

Portal site NK-ClimVault

We have developed correction technology for climate change prediction and have launched the portal site NK-ClimVault, which allows users to obtain future climate prediction information on rainfall and temperature in major cities free of charge. As a tool that anyone can use to obtain highly accurate basic climate information, it can be used for climate change adaptation business and research in various fields.
