Regarding the reduction of water use, the Third MHI Group Environmental Targets (FY2015 - 2017) establish the target of reducing unit water use in fiscal 2017 throughout the Group in Japan and throughout Group companies overseas by 3% compared with fiscal 2014 levels.

Regarding the reduction of water use, the Third MHI Group Environmental Targets (FY2015 – 2017) established the target of reducing unit water use in fiscal 2017 by 3% compared with fiscal 2014 levels, calling for a 2% reduction in fiscal 2016 against fiscal 2014 levels. We are making steady progress toward this goal: the overall Group in Japan achieved a 6.9% reduction. However the figure increased 37.5% for Group companies overseas. We are working to use water more efficiently to achieve our final-year target.

Two MHI Group factories in Japan are conducting industrial wastewater quality evaluation on a trial basis using the Whole Effluent Toxicity (WET) method (Note), and the results have indicated that no problems exist in the wastewater from these factories. The MHI Group will continue working to evaluate the safety of wastewater at an advanced level.
