Efforts to Reduce Water Risk

We recognize that access to fresh water is essential for human life and wellbeing and is recognized by the United Nations (UN) as a human right. So, we are aware that water risks in business activities are one of the business issues
We refer to the CDP Water Security Questionnaire to determine what we should do to ensure water security. We also use the Aqueduct Water Risk Atlas developed by the World Resources Institute (WRI) to identify water-related impacts on our business activities around our production bases/sites and engage in efforts to reduce water withdrawal and wastewater through effective use of water commensurate with the potential impact. In the latest evaluation, it was confirmed that, at this point, none of our bases/sites operates in areas where there is a high risk of: water supply fluctuating from season to season, water running short due to drought, groundwater running out, or limited access to drinking water in the vicinity.
Additionally, it was confirmed* that none of the Group's bases/sites withdraws water from water areas which experts deem to be vulnerable, nationally or internationally designated conservation areas or other sources that are of high value in terms of biodiversity, or sources that are deemed to be valuable or important for local communities and indigenous people. We are also not discharging wastewater to such water areas and sources, either.
As for impacts for which sufficiently accurate information is currently difficult to obtain for the Group to report on, we will work to ascertain current conditions by prioritizing areas where water risks are likely to increase in the future.

Interactions with water as a shared resource

Reducing Water Withdrawal and Water Discharges

Primarily at its production facilities, our Group mainly withdraw water from municipal water supplies or other public or private water utilities and ground water for its boiler equipment, parts processing facilities, product cooling, cooling towers, welfare facilities, and other facilities.
Regarding water withdrawal and water discharges, each production facility is responsible establishing its own goals based on the size of the facility and products they produce. We are also revamping our equipment to reuse water as much as possible in each production process.

• * At one production site in Japan, we source water from surface water (mountain springs). We used to classify such water as third-party water in 2018 and 2019, but after a third-party verification conducted in 2020, we re-classified it as surface water (mountain springs) from 2020.
• * At present, all water withdrawal is from fresh water (water whose total dissolved solids are 1,000 mg/L or less).
