Nippon Steel Corporation

In order to meet its customers’ need to promote carbon neutrality, Nippon Steel Corporation (“Nippon Steel”) newly obtained three “SuMPO EPD”*1 (former name: EcoLeaf) certifications based on the SuMPO Environmental Labeling Program by the Sustainable Management Promotion Organization, a General Incorporated Association (“SuMPO”), for its hot extruded steel shape products.

With its hot extruded steel shapes, Nippon Steel has been responding to customer needs, such as “process saving” and “advanced designability,” by supplying near-net shape products that leverage the mill properties of “free design” and “small-lot manufacturing.” Additionally, hot extruded steel shapes by Nippon Steel are employed in a myriad of sectors and for a variety of uses, starting with logistics equipment and extending to the likes of architecture (design included)/civil engineering, special vehicles, machine tools, foods/medical equipment, and semiconductor manufacturing devices. Today, their uses continue to expand further.
Furthermore, hot extruded steel shapes constitute one of the component products of NSCarbolex™ Solution*2, Nippon Steel’s highly functional product/solution technology that contributes to CO₂ emission reductions in society. By making it possible to omit tasks that necessitate welding and machining upon customer-side steel product processing, hot extruded steel shapes by Nippon Steel are helping to reduce CO₂ emissions and enabling the further reinforcement of initiatives aimed at carbon neutrality across the entire supply chain.

SuMPO EPD is an Environmental Product Declaration (EPD) certification system that uses the Life Cycle Assessment (LCA) methodology to show quantitative environmental information covering the entire lifecycle of a product, from resource extraction to manufacturing, distribution, use, discarding, and recycling. This certification system makes it possible for Nippon Steel’s customers to objectively assess the environmental impact in the lifecycle of hot extruded steel shape products as well as easier to accommodate the likes of the move to display CO₂ emissions on publicly procured goods, which will be a subject of attention going forward.
Since Nippon Steel first obtained the SuMPO EPD for H-beams in December 2019, we have obtained as many as 64 SuMPO EPD certifications for various types of products, including the three new ones.

As the movement toward carbon neutrality accelerates around the world, customers are asking for evaluations that include the materials used.
In addition to constantly pursuing the world's best technologies and manufacturing capabilities, Nippon Steel will continue to proactively disclose the environmental performance of its steel products, which are extremely recyclable and environmentally sustainable materials, while meeting the sustainability standards outlined in the Sustainable Development Goals (SDGs) adopted by the United Nations.

Note1 : SuMPO EPD, a SuMPO Environmental Label Program (former name: EcoLeaf)
A Type III environmental declaration in accordance with the ISO 14025 standard, also known as Environmental Product Declaration (EPD). EPD quantitatively discloses the information on the environment of the declared products from resource mining, manufacturing, using, disposing, and recycling. The SuMPO EPD is operated by the Sustainable Management Promotion Organization (SuMPO). (“EcoLeaf” underwent a name change to “SuMPO EPD” in April 2024.)

The three SuMPO EPD certifications that Nippon Steel recently obtained:
Hot extruded steel shapes with carbon steel
Hot extruded steel shapes with specialty steel (alloy steel)
Hot extruded steel shapes with specialty steel (others)
