Three Types of Environmental Audits

diagram: Three Types of Environmental Audits

The Mitsubishi Electric Group combines three types of audits to verify the environmental activities of each site from a multifaceted approach. The first type is environmental audits conducted by the head office at works, R&D centers and affiliated companies. The second is external audits conducted by ISO certification bodies at ISO 14001-certified sites. The third is internal environmental audits conducted by the head office, works, R&D centers and affiliated companies themselves.

From within these three types, the internal environmental audits and environmental audits target a wide range of fields, including compliance with environmental laws, precautions against environmental accidents such as toxic substance leakages, and the implementation of environmental plans. Accordingly, properly conducted audits call for a high level of specialized knowledge and communication abilities. As such, we carry out ongoing education for the purpose of training and improving the skills of auditors. For internal auditing, we conduct cross-audits among sites and offer audit training courses through internal technical education to ensure appropriate auditing skills. Through these initiatives, Mitsubishi Electric will continue to work to qualitatively improve and enhance environmental management activities throughout the Group.
