Hitachi High-Technologies GLOBAL

The Hitachi High-Technologies Group strives to reduce the burden that we place on the environment, controlling costs associated with efforts to reduce the environmental burden. We are also measuring the quantity of resource inputs into our business activities and the scale of emissions that impose a burden on the environment.

Environmental Accounting

In FY2001, the Hitachi High-Tech Group introduced environmental accounting as a tool for managing our environmental conservation activities. During the environmental accounting process, we confirm the cost effectiveness of our environmental conservation activities and conduct evaluations of the Group’s environmental activities accordingly.

The cost of environmental conservation in FY2015 was ¥2.411 million and we invested ¥533 million in the environment. Compared with FY2014, the cost of environmental conservation fell by ¥192 million, and our environmental investment fell by ¥46 million.

Comparison of Environmental Conservation Effects
  FY2014 FY2015
Reduction of Electricity Consumption ÷ A 0.44Mwh/M\ 0.47Mwh/M\
Reduction in Final Waste Disposal Amount ÷ A 2.70㎏/M\ 2.71㎏/M\

A = All environmental conservation costs - environmental conservation effects (economic effects)
From the comparison of environmental conservation effects, we can see that our activities in this fiscal year were more effective than the last fiscal year.
