Activities to transfer and diffuse decarbonization technologies overseas ECO SOLUTION
Contribute to reduction of CO2 emission on a worldwide scale
With the understanding that the transfer of Japan’s dvanced 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 75.55 million ton reduction in CO2 emissions per year in total.

Japan’s steel industry’s nternational 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.oint 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 2022, joint meetings have been held: 11 times in India and 15 times in six ASEAN countries. In 2022, we held the “2022 Public and Private Collaborative Meeting between Indian and Japanese Iron and Steel Industry” with India and the online “ASEAN-JAPAN Steel Initiative Webinar 2023 - Pathways to Carbon Neutrality” 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. 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 for the ASEAN countries, into the fourth version on BF steelmaking and 3.2 version on EAF steelmaking in fiscal 2021.
Technologies customized list
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 2022, we had carried out the assessment of 14 steel mills in India and 16 mills in six ASEAN countries.

Activities as a Climate Action member
Nippon Steel participates in the Climate Action Program of the World Steel Association, which uses universal methods to calculate and report on the CO2 emitted by steelworks. As a Climate Action member (data provider), our 15 years of contribution has been highly recognized.
