The EcoLeaf Environmental Product Declaration(*) for steel sheet piles (including
NS-PACTM Sheet Piles) was published by Nippon Steel Corporation (“Nippon Steel”).
The EPD program is operated by Sustainable Management Promotion Organization (“SuMPO”).
Nippon Steel’s steel sheet piles are used in construction fields, including river revetments, port
and harbor structures, roads, retaining walls and cofferdams, and widely appreciated in the market for
their excellent quality and drivability. Drawing on a wealth of accumulated technical expertise for
rolling, fabrication and utilization in these fields and taking advantage of the quality characteristics
of its steel sheet piles, Nippon Steel has developed various new products, such as hat-type sheet piles
with superior drivability and cost-effectiveness and NS-PACTM Sheet Piles with high corrosion
protection that is required for port and harbor structures.
EcoLeaf is an EPD(*) certification system that uses the Life Cycle Assessment (LCA) methodology to show
quantitative environmental information covering the entire life cycle of a product, from the raw material
supply, transportation, manufacturing, assembly, use, waste processing and recycling. This allows our
customers to assess the environmental impact throughout the life cycles of the steel sheet pile products.
By using our steel sheet piles, our customers can obtain benefits such as labor-savings in construction,
lighter weight, and longer service life, reducing CO2 emissions throughout the supply chain to help their
efforts toward carbon neutrality. Our customers can also respond to the movement toward indicating CO2
emissions for publicly procured goods, which is expected to attract attention in the future.
Since December 2019, when Nippon Steel first obtained the EcoLeaf environmental product declaration for
H-shapes, we have thus far obtained total of 43 EPDs for various products, covering most of our steel
products. As the movement toward carbon neutrality is accelerating worldwide, growing numbers of customers
of various sectors evaluate the materials they use.
Nippon Steel will pursue world-leading technologies and manufacturing capabilities while aggressively
disclosing the environmental performance of steel products, which are highly recyclable, environmentally
friendly, sustainable, and in compliance with the Sustainable Development Goals (SDGs) adopted by the
United Nations.
