We monitor and manage our business activities so that they do not adversely impact the surrounding environment
For pollution control, the Hitachi Group uses voluntary standards stricter than those imposed by law. As well, we share information within the Group on major regulations and new legislation. In fiscal 2008, there were no environmental incidents resulting in fines, but there were four where legal limits were exceeded. In all four cases, the cause was identified and the issue resolved before the end of the fiscal year. To prevent incidents from happening or reoccurring, we rigorously monitor and manage data.

We are working to prevent leaks of chemical substances into the soil or groundwater by converting underground piping, pits, and tanks to above the ground, making inspections easier. Underground tanks not yet converted are carefully tested for corrosion and inspected using such techniques as ultrasonic testing.
Up to fiscal 2008, 90 percent of facilities that use chemicals have reported completing groundwater and soil decontamination, or that there is no contamination. The remaining facilities are taking countermeasures, and we continue to monitor groundwater at all locations.
