Basic Policy on Water Resource Reduction

The Daikin Group determines how much water it uses at its manufacturing sites and recycles as much water as possible in order to reduce water usage throughout the entire group.

In addition, as a company doing business globally, we identify bases where water risk exists and strive to protect water resources throughout the entire value chain.

Reducing Water Usage

Reusing Waste Water to Reduce Water Intake

At our plants, we periodically repair and patrol equipment that uses water in the production processes. The Daikin Group strives to reduce the water it uses by measuring the amount of water used and trying to reuse as much waste water as possible. Since fiscal 2013, we have been striving to meet a target of reducing fiscal 2020 water intake per unit of production by 5% against the standard value (the average water intake in fiscal 2015).

In fiscal 2016, by utilizing wastewater recycling equipment and using rainwater, and by modifying the purifying process, we reduced water intake per unit of production by 6% in Japan and by 3% overseas.

Note: Because the scope of calculations and the calculation method were revised in formulating the 2020 Environmental Action Plan, the past fiscal year values were retroactively corrected.

Response to Water Risk

Operation Surveys in Water-stressed Regions

Water risk has become a pressing issue in recent years. Based on the Aqueduct water risk mapping tool of the World Resources Institute (WRI), since fiscal 2014 the Daikin Group has been surveying water-stressed regions. As a result, we have determined that we are operating in five regions, including India and inland China, where water stress is an issue.

Starting in fiscal 2015, in these regions and in production processes where we use large amounts of water, we decided to consider the amount of water intake minus the amount of wastewater as a loss of water resources. We therefore began surveying this amount of loss.

In the near future, we intend to reflect this effort in our Green Procurement Guidelines and have our suppliers start conducting surveys themselves, all as part of efforts to better manage water resources throughout the value chain.
