Komatsu's Environmental and Social Activities Enhancing Quality of Life

Environmental Risk Management  Reducing the Use of Substances of Environmental Concern and Complying with the EU REACH Regulation

Komatsu has been making efforts from an early stage to reduce the use of asbestos, lead, and other substances of environmental concern. In FY1999, Komatsu created its own list of banned substances and substances approved for use only in limited circumstances(Refer to "Substances of Environmental Concern Banned or to Be Reduced for Use in Products"), which was based in part on the chemical substances banned under Japanís Law Concerning the Examination and Regulation of Manufacture of Chemical Substances Control, as well as regulations in other countries.

In addition, Komatsu has begun comprehensive control of substances of environmental concern. Recently, in compliance with REACH*1, Komatsu began revising its listing of substances designated as approved for limited use, "to be reduced," and "banned." Through the cooperation of suppliers, the Company has initiated a system to strengthen control of substances of environmental concern in its products. This system has been deployed in Japan and Europe, and is also being implemented in other overseas subsidiaries.

By using this system, we identify SVHC (substances of very high concern) in vehicles currently in production and in newly developed vehicles. Furthermore, we also regularly check for new SVHCs to be added to the list.

There are currently 138 SVHCs registered, but more are added on a bi-yearly basis. In future, it is said that the number of SVHC will increase up to 1,500. Komatsu has devised a workflow to monitor control of these substances.
