Environmental Evaluation by External Parties

Introducing KIOXIA's awards and evaluation by external parties.

Yokkaichi Plant receives Minister of the Environment Award (FY2020)

KIOXIA’s Yokkaichi Plant received the “Climate Change Action: Minister of the Environment Award (in the dissemination and promotion category of the mitigation field)” in November 2020. This award is a part of the promotion of measures tackling climate change issues and it recognizes individuals or groups who have made remarkable achievements to prevent global warming. We were recognized for our cross-departmental energy-saving activities at our Yokkaichi Plant and also our activities to address climate change in close relationship with the local community.


We have organized an energy-saving promotion committee headed by the factory general manager, and each subcommittee across the plant made targets and implemented energy-saving measures every year. The energy-saving measures across the plant in FY2019 cut approximately 20,000 tons of CO2. We also focused on PFC gases, which have a high greenhouse effect coefficient, and we have installed 100% of abatement equipment. We managed to cut 90% or more of these gases.

We have also developed long-standing awareness-raising activities such as providing environmental education for children at neighboring elementary schools, posting energy-saving information within factory premises, and holding charity eco bazaars.


In the future, we will continue to promote energy-saving activities and implement community-based environmental preservation events.

Results of disclosing environmental information to CDP (FY2021)

In FY2021, KIOXIA responded to a survey from CDP (Carbon Disclosure Project), the world's largest environmental information evaluation organization, having done so last year as well. Our responses were evaluated as follows:

CDP Climate Change

This evaluates a company's risks, opportunities, and responses regarding climate change. In FY2021, we were rated B (management level).

CDP Water Security

This evaluates a company's efforts on water stewardship. In FY2021, we were rated B (management level).

About CDP: CDP is an international not-for-profit organization established in 2000 to tackle environmental issues, including climate change and water risks. It collects information from major companies around the world using questionnaires on the subject of management risks that climate change and other environmental issues pose to companies, and it rates them on an 8-point scale from A to D− (A is the highest grade) based on the received responses. In 2021, it received responses from over 13,000 companies and provided information to over 600 institutional investors.
