Building Environmental Management System
At Hitachi Construction Machinery Group we have been active in promoting the development of an environmental management system as the architecture for our environmental conservation activities. After acquiring ISO14001 certification for the Tsuchiura Works in 1997, we have gone on to expand the scope out to newly established works.In 2012 we integrated the environmental management systems for the Head Office Sections and Works Sections. We are also making progress with configuring the environmental management system for our group companies in Japan and overseas in order to raise the level of our environmental conservation activities.
Environmental Management System Certification Status
Hitachi Construction Machinery Group is promoting the acquisition and maintenance of ISO 14001 facilities and other EMS (Environmental Managing Systems) with a focus on production group companies that account for over 95% of the environmental impact.
In FY2024, 91.7% of production companies attained ISO 14001 certification including simple version of EMS. For bases that have not obtained ISO 14001 or a simplified EMS, we conduct internal audits and periodically inspect the status of compliance with environmental laws and regulations, management systems, etc.
