The Commitment to a Low Carbon Society
The Japan Iron and Steel Federation (JISF) is promoting its Commitment to a Low Carbon Society, which focuses on the Three Ecos initiatives and the development of innovative new iron and steelmaking processes. JFE Steel is actively implementing initiatives to help achieve the plan’s targets.

|Three Ecos||Eco Processes||Eco Products||Eco Solutions|
|Goal||Further improve energy efficiency by taking full advantage of cutting-edge technologies||Provide high-performance steel materials that result in high performing end-products and thus reducing CO2 emissions||Reduce CO2 in developing countries through the transfer and application of world-leading, energy-saving Eco Process technologies|
|Reduce CO2 emissions by 5 million t-CO2 compared to the BAU benchmark
• Energy-saving: 3 million t-CO2
• Efficient use of waste plastics, etc.:2 million t-CO2
|The use of major high-performance steel materials to contribute to a CO2 reduction of approximately 34.0 million t-CO2||Estimated CO2 reduction impact of 70 million t-CO2|

Assessment of Commitment to a Low Carbon Society Results (JISF)
In FY2018 emissions by the Japanese steel industry decreased by 2.21 million t-CO2 compared to the BAU emissions* benchmark. Various self-improvement efforts, such as raising the efficiency of coke ovens and generation facilities, are steadily contributing to this reduction. JFE Steel is actively working on these self-improvement efforts as well as investing in research and development for new energy-saving technologies.

Revolutionary Iron and Steelmaking Process Development
About 30% of CO2 emissions can be reduced through hydrogen reduction along with separation and capture of CO2 from blast furnace gases. The first facility is expected to come online by 2030, followed by other plants by 2050.
The Japanese steel industry intends to develop ferro coke that accelerates and lowers the temperatures of the reduction reaction in a blast furnace as well as its operational processes to conserve energy further and expand the use of low-rank materials. Currently, a medium-scale plant capable of producing 300 tonnes of ferro coke per day has being constructed in JFE Steel’s West Japan Works (Fukuyama district) and test for practice use aimed for the FY2020 operation will be started.
Reduced CO2 Emissions through High-performance Steel Materials (Effects of Eco Products)
The Japan Iron and Steel Federation (JISF) expects the use of high-performance steel materials to reduce CO2 emissions. It is estimated that the use of 5 major high-performance steel materials for cars, transformers, ships, power generator boilers, and trains in Japan and overseas (FY2018 production: 6.97 million tonnes, 6.8% of crude steel production) helped to reduce CO2 emissions by 31.06 million tonnes (10.10 million tonnes in Japan, 20.96 million tonnes overseas) in FY2018.
• Estimates created by the Institute of Energy Economics, Japan
• Materials included are steel sheets for automobiles, directional electrical steel sheets, thick steel sheets for shipbuilding, steel tubes for boilers, stainless steel sheets.
• For the domestic figures, the calculation includes data from FY1990 onward. For the export figures, the calculation includes data from FY2003 onward for automobile and shipbuilding, from FY1998 onward for steel pipes for boilers and from FY1996 onward for electrical steel sheets.

Global Scale Initiatives
Addressing Global Warming
ISO 14404 is an international standard proposed by the Japan Iron and Steel Foundation (JISF) to the International Organization for Standardization (ISO) as a methodology for the globally unified calculation of CO2 intensity from iron and steel production, ultimately to assess the energy efficiency of steelworks. The Japanese steel industry is addressing global warming through international public-private collaborations, including ISO 14404-based assessment of steelworks in developing countries and recommending specific technologies best suited to India and ASEAN countries. It is continuing this effort together with the Ministry of Economy, Trade and Industry (METI) in order to enhance ISO 14404 so that it can be applied to steel manufacturing facilities with more complex structures.
JFE Steel is also addressing global warming by participating in international activities, such as the Japan India Public and Private Collaborative Meeting, the Japan-ASEAN Steel Initiative and the Japan-China Steel Industries Exchange. In addition, JFE Steel is involved as a member of World Steel Association (WSA)’s Climate Action Program, which uses ISO 14404 as the standard for measurement and calculation.
Contribution to the Development of Calculation in LCA
In order to accurately evaluate the environmental impact of products, assessment and quantification is required over their entire life cycles, from raw resource mining to material production, product manufacture, use and final disposal. Life Cycle Assessment (LCA) is one method for conducting this evaluation.
After final products such as automobiles and buildings finish their mission in society, all of their steel components can be recycled and reused. This closed loop recycling ability is an excellent characteristic of steel materials. If LCA is conducted and this characteristic is taken into account, steel can be viewed as having extremely low environmental impact compared to other materials.
The standard for appropriately considering this ability of steel products to undergo closed-loop recycling was published in November 2018. ISO 20915 (life cycle inventory calculation methodology for steel products) was developed by The Japan Iron and Steel Foundation (JISF) with JFE Steel playing a major role, and provides a life cycle inventory (LCI) calculation method specific to steel products that takes into account the effects of recycling.
In addition, the Japan domestic version of this standard, JIS Q 20915 (life cycle inventory calculation methodology for steel products), was published in June 2019.
Notes: JFE Steel, together with the WSA (World Steel Association, comprising of approximately 170 steel manufacturers and steel related organizations) and the Japan Iron and Steel Foundation (JISF), is working to establish LCA as an international standard methodology for calculating LCI for steel materials.
