Current Status of Environmental Impact and Environmental Targets and Outcomes

Current Status of Environmental Impact

The following tables outline the environmental impact (material balance) of manufacturing activities at KIOXIA. Although the environmental burden shows an increasing trend due to
KIOXIA’s increased production capacity resulting from our information infrastructure expansion, we continue to work to reduce this burden through various reduction activities. For details of the environmental impact of Yokkaichi Plant and their environmental activities, see "2019 Yokkaichi Plant Environmental Report" (PDF:4.5MB).

Targets and Outcomes in FY2018

KIOXIA group promotes business activities that contribute to the sustainability of society by setting environmental targets and objectives. The following table summarizes the environmental targets of KIOXIA for 2018, their achievement status. We achieved all environmental targets in FY2018 by the contribution of our cross organizational energy saving activities and waste reduction efforts at our manufacturing plants. We are also actively carrying out social contribution activities with employee participation mainly at our manufacturing plants.

In FY2018, we adopted “rate of change of environmental impacts per unit of GB (gigabyte) from FY2013 basis” as our targets, excluding the Reduction of CO2 emissions from energy sources. Accompanying its plan for business (production line) expansion, the environmental impact of KIOXIA is expected to increase in 2019 compared with the previous year, we will continue to undertake cross-functional and innovative environmental initiatives.
