Eco-friendly Products

Basic Concept

In addition to reducing the environmental impact of our business activities, we also aim to reduce the environmental impact of our products throughout their entire life cycle, including when they are used and recycled at our customers' sites. By acquiring external environmental certifications such as the "EcoLeaf" and "Carbon Footprint of Products (CFP)", we believe that we can be easily selected by our customers and thus contribute to reducing the environmental impact of society as a whole.

Development of Eco-friendly Products and Services

Although steel is a material that can be recycled semi-permanently, the entire life cycle of steel, including manufacturing, distribution, use, disposal, and recycling, has an environmental impact, such as the generation of CO2. Our group has acquired environmental certification to produce eco-friendly products and services with reduced environmental impact and to allow our customers to make objective judgments. We will continue to maintain reliability and transparency while balancing the environment and management.

Obtaining Eco-label Certification

Yamato Steel has acquired two types of environmental declaration certification, the EcoLeaf, and the Carbon Footprint of Products (CFP), from the Sustainable Management Promotion Organization, for six of its products*, including H-beams. Yamato Steel is the first company in the steel industry in Japan to acquire these two types of certifications.
In the future, we will further expand our recognition through sales activities and actively promote the development and diffusion of eco-friendly products.

* Certified products: H-Beams, I-Beams, Channel Steel, Steel Sheet Piles, High-spec H-Beams, and Patterned H-Beams, listed in Yamato Steel’s product catalog.

What is the EcoLeaf?

  • The Japan EPD Program by SuMPO is a certification program that uses a Life Cycle Assessment (LCA) method and calculates and discloses quantitative environmental information on the environmental impact of value chains at each stage, ranging from raw material procurement to production, distribution, use, disposal, and recycling.
  • The EcoLeaf complies with ISO 14025 standards and is referred to as a Type Ⅲ environmental declaration (EPD). A third party externally verifies this certification from the perspective of reliability and transparency.

What is the CFP?

CFP is an abbreviation for Carbon Footprint of Products.
CFP is one of the systems to convert greenhouse gases emitted during the entire product life cycle into carbon dioxide emissions and quantify them to realize a low-carbon society.
This system can be used as an incentive for both businesses and consumers to take action to reduce greenhouse gases.
