Japan’s second largest steel maker JFE Steel Corporation has acquired EcoLeaf from the Sustainable Management Promotion Organization in Japan for tinplates, JFE Universal Brite laminated steel sheet and tin-free steel. Data visualization enabled by EcoLeaf will increase the transparency of environmental impact of JFE products. JFE Steel’s tinplate, laminated steel sheets, tin-free steel sheets, including those for beverage and food cans, are essential materials that support everyday life in diverse settings. Moreover, they offer excellent recyclability of as high as 94% for steel cans, allowing their steel material to be reused over and over in other products. In addition, the per-unit environmental impact of steel in manufacturing is extremely lower than that of other materials and thus steel is an essential material for the realization of a sustainable society. Moving forward, JFE Steel intends to utilize EcoLeaf certification of its various products to promote global environmental conservation initiatives by customers as well as to strengthen transparent communications with customers. EcoLeaf is a Type III environmental labeling system created in Japan for disclosing environmental information about products across all stages using life cycle assessment methodology. The system enables customers to quantitatively and objectively evaluate the environmental impact of products based on manufacturer data that has been confirmed fairly and reliably through third-party examinations and verifications. To support the EcoLeaf environmental labeling program, the Japan Iron and Steel Federation developed the Product Category Rule for calculating the environmental impact of products, for which it received authorization in August 2019. The PCR complies with the ISO 20915 and JIS Q 20915 standards, both of which account for recycling capacity when determining the quantitative environmental impact of steel products. In May 2021, parent company JFE introduced its JFE Group Environmental Vision for 2050. As part of a broad-based initiative to achieve carbon neutrality by 2050, the group is actively expanding its initiatives to reduce CO2 emissions through more eco-friendly products. JFE Steel, in addition to reducing its own direct CO2 emissions, is committed to contributing to a more sustainable world by supplying high-quality, eco-friendly steel products.
