Water Risk Management

Identification of and Response to Water Risks

In the semiconductor manufacturing industry, which uses a large amount of water, securing and circulating water resources is not only a lifeline for business, but also an important issue that must be addressed as a social responsibility for companies that conduct business activities using natural capital.
ROHM Group is working to reduce water risks (droughts and floods) at all of its 24 sites by using the WRI Aqueduct, a global assessment tool for identifying water risks.
Specifically, four sites were identified as high-risk sites based on the assessment of water stress and water depletion, and river flooding risk and coastal flooding risk.
For drought risk, we have set targets for improving the water recovery and reuse rate and are working to maximize resource recycling through the introduction of wastewater recycling facilities and other measures. For flood risk, the Risk Management/BCM Committee conducts risk assessments and analyses, and from a BCP perspective, we are working to reduce the risk of production stoppages due to flooding by designing BCP inventories based on the expected number of days of stoppages.

Waste Management

In order to eliminate waste of limited resources and energy, reduce waste, and recycle resources in a series of business activities from material procurement to development, production, and sales, the Resource Utilization Subcommittee plays a central role in setting up an implementation plan for each fiscal year to achieve the target and promote activities. We continue to achieve zero emissions. To contribute to a sustainable society, we will continue to procure resources with less environmental impact, minimize new resource inputs and waste emissions, and use resources in a sustainable manner.
