Epson and the Environment


Environmental Risk Management

Any environmental pollution resulting from Epson's business activities could have a serious impact on residents of the surrounding area, as well as for the rest of the region or country. We follow Group-wide standards for pollution control and ensure that all members are well acquainted with the ideas and laws of environmental risk management. Each promotion unit uses ISO 14001 to identify and assess the risk of failing to meet standards or of experiencing environmental complaints or incidents in an ongoing effort to continuously mitigate those risks.

Regulatory limits for oil were exceeded once during fiscal 2014. This incident was reported to the government and is being addressed.
We did not have any complaints and accidents.

Soil and Groundwater Remediation

Epson is pumping and treating groundwater contaminated by chlorinated organic solvents at several sites in Japan, including at its Head Office. In addition, we have barriers in place to prevent further contamination. In addition, treated wastewater discharged into sewers is monitored to ensure that it remains within 1/1000th of the discharge standard (0.3 mg/liter).
