The Japanese government has been promoting JCM (Joint Crediting Mechanism) as part of measures against global warming. JCM is a system whereby Japan contributes to sustainable development in developing countries by spreading superb low carbon technologies, products and services and implementing measures. Japan’s contributions to reducing greenhouse gas emissions are quantitatively evaluated, and such reductions are utilized as credits as part of Japan’s achieving its reduction targets.

Seventeen countries have signed a JCM partnership agreement. Since 2013, Sumitomo Electric has been working on a project to demonstrate and verify power loss reduction by introducing energy-saving power transmission systems in Mongolia, one of the signatories.

This project is part of an undertaking implemented by Hitachi, Ltd. under a commission from the New Energy and Industrial Technology Development Organization (NEDO). Sumitomo Electric delivered low-loss, large-capacity power cables for the power transmission line between Oyu Tolgoi Substation and Tsagaan Suvarga Substation, through which electricity was supplied to mines and areas where no electricity had been available. The transmission amount was monitored, and the effect of reducing the power transmission loss was converted into carbon dioxide (CO2) emissions.

The one-year monitoring period is now over, and we are eligible to apply for issuance of CO2 reduction credits.

In February 2019, Sumitomo Electric received a certificate of appreciation from Mongolia’s National Power Transmission Grid for introducing advanced technologies that help reduce greenhouse gases emissions and the consequent contribution to Mongolia’s economic development and electric power supply to areas without electric service.

Through the development of unique products and technologies, Sumitomo Electric continues its efforts to tackle environmental issues by stabilizing electric power supply, promoting energy saving and reducing greenhouse gases emissions in and outside Japan.
