Water resource conservation initiatives

Under the azbil Group Basic Environmental Policy, we continue to work to reduce the environmental impact of our business activities with respect to water resources.

Water use condition

In addition to implementing various water conservation measures, we are reusing wastewater from clean rooms and using rainwater. By continuing application of these measures, we aim to reduce the amount of water used each year to below the level of the previous year. As a system to implement this initiative, the azbil Group Environmental Committee holds a review meeting three times a year with the azbil Group’s executive officer responsible for the environment.

In FY2020, the Group’s bases used 107 million liters of water, a year-on-year decrease of 18%.

Dealing with Water-Related Risk

The azbil Group endeavors to understand and reduce the amount of water used by the Group’s bases and also uses WRI Aqueduct*1 to evaluate water risks at each location from a business continuity standpoint. Based on the results of the risk assessment, we recognize that we have water risks at our China (Dalian) and Thailand bases, which account for about 20% of our total water usage. The azbil Group’s measures to mitigate water risk and reduce the amount of water used were rated B- by CDP Water 2020.*2

*1.Comprehensive maps provided by the World Resources Institute (WRI) about the state of water risks in all r egions of the world.
*2.A disclosure program about corporate water risks, created by the international nonprofit organization CDP. It investigates the status of water-related initiatives of participating corporations every year and officially publishes the aggregated results. It also gives each corporation an individual rating for the status of its initiatives in an eight-step evaluation with A as the highest grade.
