Contribution in the global value chain

Contribute to reduction of CO2 emission on a worldwide scale

With the understanding that the transfer of Japan’s advanced energy-saving technologies overseas can be effective ways to globally reduce CO2 emissions, Nippon Steel is participating in many energy-saving and environmental initiatives in Japan and overseas. For example, we work with the World Steel Association and directly with countries such as China and India.

Japan’s steel industry can contribute to reduction of CO2 emission on a worldwide scale by transferring its advanced energy-saving technologies to emerging countries. The reduction effects of CO2 emission by transfer of Japanese steelmakers’ energy-saving technologies have amounted to 72.64 million ton reduction in CO2 emissions per year in total.

Japan’s steel industry’s international cooperation in energy conservation

As a core member of the Japan Iron and Steel Federation (JISF), Nippon Steel is involved in multinational projects such as those for the Environment Committee of the World Steel Association. In addition, the JISF is promoting 1.joint meetings of public and private steel-related parties, 2.preparation of customized list of technologies, and 3.assessment of steelworks as to energy-saving status. These are the three pillars of collaboration for bilateral energy-saving and environmental cooperation with India, Southeast Asia, and other countries and regions.

1.Joint meetings of public and private steel-related parties

In public-private steel-related joint meetings, we share the Technologies Customized List, the results of assessment of steel mills, and introduce detailed technical information and financing schemes, in order to realize the early transfer of energy-saving technologies to emerging countries. By fiscal 2021, joint meetings have been held: 10 times in India and 14 times in six ASEAN countries. In 2021, we held the “2021 Public and Private Collaborative Meeting between Indian and Japanese Iron and Steel Industry” with India and the online “AJSI Webinar 2021” conference with ASEAN countries and shared examples of energy saving and environmental conservation measures.

2.The technologies customized list

We identify the appropriate technologies for each country and region, and in addition to detailed technical information, we conduct the assessment of steel mills, and provide the Technologies Customized List, which complies information such as on suppliers, for reference. In fiscal 2021 the technologies customized list was updated into the fifth version on blast furnace (BF) steelmaking and the 4.2 version on electric arc furnace (EAF) steelmaking for India, and into the fourth version on BF steelmaking and 3.2 version on EAF steelmaking for the ASEAN countries.

3.Assessment of steelworks

Experts from the Japanese steel industry visit the steel mills overseas to propose energy-saving technologies, provide operational improvement advice based on the operational conditions of the facilities, and conduct the energy-saving assessment of steel mills using the international standard ISO14404. Up to fiscal 2021, we had carried out the assessment of 13 steel mills in India and 15 mills in six ASEAN countries.
