Technical cooperation and transfer promoted on a worldwide scale
Contribute to reduction of CO2 emission on a worldwide scale
Japan's steel industry, including Nippon Steel, plays a leading role in the Global Sectoral Approach, a worldwide initiative to preserve the environment and conserve energy based on technologies accumulated in the steelworking industry. 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 where there is the potential to improve energy efficiency. The reduction effects of CO2 emission by transfer of Japanese steelmakers' energy-saving technologies have amounted to 62.59 million ton reduction in CO2 emissions per year in total. This is equivalent to about one-third of CO2 emissions of Japan's entire steel industry.

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 2020, 19 joint meetings have been held: 9 times in India and 13 times in six ASEAN countries. In 2020, we held the online “AJSI Webinar 2020” 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 2018 the technologies customized list was updated into the fourth version for India and into the third version 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 2020, we had carried out the assessment of 12 steel mills in India and 14 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. We have been selected as a Climate Action member.
