For chemical substance management, the Environmental Promotion Department takes the lead in creating and implementing a basic management manual (Product Chemical Substance Management Standard). To monitor implementation, an Environmental Quality Internal Audit Checklist is used. The Environmental Promotion Department and the EMS Internal Audit Team conduct audits at all plants. Audit results are reported to management, linking into the management review system.
In addition to substances regulated by the RoHS Directive, our group has established a list of prohibited substances that includes substances required by customer specifications, voluntarily prohibited substances, and substances regulated by other environmental laws. Furthermore, we have established a list of controlled substances that must be tracked for presence and content. We have also established a list of substances subject to reporting requirements, which includes substances of very high concern (SVHC) subject to authorization under the REACH Regulation.
These are also listed in our Green Procurement Guidelines, and we require our suppliers to submit a guarantee of non-use of prohibited substances. We have introduced X-ray fluorescence analyzers and phthalate screening systems to periodically check the content of environmentally hazardous substances in materials and parts delivered by our suppliers.

Our company uses large volumes of groundwater. For wastewater, we regularly have third-party organizations analyze the water quality to confirm compliance with locally established discharge standards. We also implement regular monitoring based on our own internal standards.
