Our company adopts the environmental policy of Marubeni-Itochu Steel Inc. as our basic philosophy and framework. Recognizing that protecting the irreplaceable global environment and passing it on to the next generation is a shared responsibility of all humankind, we contribute to the sustainable development of human society.

Basic Policy

Through our domestic trading and processing of steel products, we set the following basic policies to engage in activities that reduce environmental impact.

Consideration for the Natural Environment
In conducting our business activities, we give consideration to local communities and the natural environment, and strive to prevent pollution.
  1. We recognize the environmental impact of the products we handle and our processing activities, and conduct transactions with due regard to conserving natural ecosystems.
  2. When implementing business investments and development projects, we assess their environmental impact and give appropriate consideration to the environment.
Compliance with Environmental Laws and Regulations
We comply with international environmental treaties and the environmental laws, regulations, and other requirements of Japan and relevant countries.
Efficient Use of Resources and Energy & Realization of a Circular Economy
We strive to use resources and energy efficiently and contribute to the realization of a circular economy.

LRQA

CSR | Social Contribution

Through our business activities, we contribute to building a better society.

The steel pipes we handle emit large amounts of CO2 in their production and transportation processes, and their impact on the environment is significant.

By accurately understanding the needs of the steel pipe market and working in partnership with manufacturers and trading companies, we help curb excessive production while still meeting market needs.
In addition, by operating warehouses across Japan to store and distribute products, we realize efficient logistics with minimal waste.
By capturing needs correctly (producing no more than necessary) and providing functions that enable efficient transportation, we contribute to minimizing environmental impact.
