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 the manufacturing activities at KIOXIA.
Although the environmental burden shows an increasing trend due to KIOXIA’s increased production capacity resulting from expansion of our information infrastructure, we continue to work on reducing this burden by means of various initiatives.
For details of the environmental impact of Yokkaichi Plant and their environmental activities, see the "2020 Yokkaichi Plant Environmental Report" (PDF：7.2MB).

Targets and Outcomes

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 2019 and their achievement status.

We again achieved all environmental targets in FY2019 thanks to our energy-saving activities promoted across the organization and efforts to reduce the amounts of used and discarded chemical substances at our flash memory manufacturing plants. We are also actively carrying out social contribution activities with employee participation and biodiversity conservation activities, primarily at our manufacturing plants.

We adopted the “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 our plans for production line expansion, the environmental impact of KIOXIA is expected to increase in 2020 compared with the previous year, and we will continue to undertake cross-functional environmental initiatives.
