Reducing the Amount of Water Used


Our Approach

The risk of a global water shortage is on the rise, due to such factors as climate change, the destruction of forests, and the economic growth and population boom in emerging and developing countries. Such a water shortage is a risk for companies as well, since it may very well affect the survival of their businesses. As such, it is important for us to recycle and reduce the amount of water we use.

Since the Fujitsu Group uses particularly large amounts of water in the manufacture of semiconductors and printed circuit boards, we believe it is necessary to reduce our water consumption in these areas especially. In addition to our general water conservation efforts, we have also worked to reuse and recirculate water, through methods such as pure water recycling and the reuse of rainwater. We are continuing our efforts to effectively use water resources in the Environmental Action Plan (Stage X).

FY 2022 Performance

Targets under the Fujitsu Group Environmental Action Plan (Stage X)FY2022 result
Adding policies to reduce water consumption and reducing water usage by at least 30,000 m3 by the end of FY 2022. (*1)Water consumption was reduced 31,000 m3 (target for FY 2022: 19,000 m3)
  • (*1)
    Target organizations: Japan; Fujitsu and Fujitsu Group offices (excluding data centers)
    Overseas; Fujitsu and Fujitsu Group manufacturing sites

The policies we established in FY 2022 to reduce water usage include reducing the amount of water used in coating and cleaning processes, reviewing our water supply and wastewater through actions such as optimizing the water supply for our scrubbers, and upgrading air conditioners from water-cooled units to air-cooled units. We implemented these policies at each business site, plant, etc., so that we could make more efficient use of our water resources. As a result, in FY 2022 we reduced our water usage by 114,000 m3, which is 380% of the target of 30,000 m3 as was set in the Fujitsu Group Environmental Action Plan (Stage X).

Water Usage in FY 2022 was 6.15 Million m3 (a 11% Reduction Compared to the Previous Fiscal Year)

The total amount of water we used in FY 2022 was 6.15 million m3 (output level per sales amount: 166 m3/100 million yen), a reduction of 11% compared to FY 2021. Additionally, 3.86 million m3 of that usage was recycled water, which was an increase of 14.3% in comparison to FY 2021. The total amount of water we used declined, so recycled water comprised 62.8% of our total water usage, a 13.8%pt increase from FY 2021.
