Targets and Outcomes

Toshiba Memory Corporation promotes business activities that contribute to the sustainability of society by setting environmental targets and objectives. The following table summarizes the environmental targets of Toshiba Memory Corporation for FY2017, their achievement status, and the targets for FY2018. We met the environmental targets in FY2017 except for two wastes generation targets due to increase of chemical solutions usage and wastewater sludge discharge in association with production increase.

From FY2018, we adopted “environmental impacts per unit of GB (gigabyte) basis” as our intensity targets, excluding the Reduction of CO2 emissions from energy sources.

Accompanying its plan for business (production line) expansion, the environmental impact of Toshiba Memory Corporation is expected to increase in 2018 compared with the previous year, we will continue to undertake cross-functional and innovative environmental initiatives.
