Environmental Management System

At our domestic and overseas manufacturing sites, we are implementing environmental protection PDCA in accordance with the EMS (ISO 14001) for each of our sites, and are promoting the Tsubaki Group’s unique environmental improvement activities.
The environmental management system at each business site includes setting environmental policies and targets, evaluating compliance with environmental laws and regulations, identifying risks and opportunities through environmental impact assessments and taking initiatives, conducting internal audits and management reviews, responding to emergencies, and managing communications with stakeholders.

ISO 14001-Certified Plants and Divisions

In 2001, the Tsubaki Group’s Saitama Plant and Hyogo Plant acquired ISO 14001 certification, and all domestic company sites (including those of our Group companies) have since acquired the same certification. Overseas, a total of 15 major subsidiaries and plants have been certified.

Extraction of Material Issues Related to the Environment

When extracting material issues related to the environment, we evaluate both the degree of impact on our business (horizontal axis) and the degree of importance to stakeholders (vertical axis).
In addition, the degree of importance to stakeholders (vertical axis) is evaluated based on the magnitude of the negative side (risks to be reduced) and the positive side (opportunities to improve financial indicators).
