Ena City, NGK, Ricoh, and IHI to Start Trial Project for Decarbonization and Economic Circulation System

Establishing a Scheme to Convert Environmental Value into Credits and Create a Positive Circulation between the Environment and the Economy

Ena City (Gifu Prefecture; Mayor: Takane Kosaka), NGK INSULATORS, LTD. (hereinafter “NGK”), Ricoh Company, Ltd. (hereinafter “Ricoh”), and IHI Corporation (hereinafter “IHI”) will start a trial project in October 2022 for a decarbonization and economic circulation system. The system will convert the environmental value gained by Ena City through the generation and sales of electricity from the renewable energy of the regional power producer and supplier Ena Electric Power Co., Ltd. (hereinafter “Ena Electric Power”) into economically compensable value (“credits”) and make use of those credits.

The credits generated will be used within Ena City, and a scheme will be developed to generate inflows of funds from outside the city. The system will help to turn Ena City into a zero-carbon city by promoting a cycle in which the scheme revitalizes the local economy and encourages the further expansion of the introduction of renewable energy.

Since April 2022, NGK and Ricoh have been conducting a trial project for using blockchain technology to perform tracking of all processes of Ena Electric Power's renewable energy from generation to consumption, including charging and discharging of surplus energy to NAS® batteries for storing electricity. The project is tracking the consumption of renewable electric power generated and consumed in-house at Ena City’s public facilities, and it is deemed to represent environmental value held by the city in the form of carbon dioxide (CO2) reductions.

The trial project to be initiated will use an environmental value platform developed by IHI to convert this environmental value into credits through the J-Credit Scheme. The environmental value held by the city will be converted into credits and sold to businesses and producers in the city. This will encourage the development of carbon offset products with added environmental value and will help to boost the environmental brand power of Ena City, which has been selected as an SDGs Future City. In the future, the project aims to establish a positive environmental and economic circulation scheme that maximizes environmental value by using the inflow of funds generated from outside the city through the project to encourage the further introduction of renewable energy and energy conservation.

In the past, there were mechanisms in place to generate and trade environmental value, such as COreductions, through in-house consumption of renewable energy. However, these mechanisms were burdened by time-consuming procedures because they required manual and complex work, such as data collection and the filing of applications with various documents. This project will strive to streamline the procedures through to credit conversion by utilizing Ricoh and IHI’s digital technologies and IoT technology.

Through this trial project, the project’s partners will help to turn Ena City into a zero-carbon city and establish a decarbonization and economic circulation system that will serve as a model case for local governments across the country, with the aim of achieving carbon neutrality by 2050.
