Hitachi High-Technologies GLOBAL

The Hitachi High-Tech 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

The Hitachi High-Tech Group has introduced environmental accounting since FY2001 as a tool for managing our environmental conservation activities. We confirm our cost-effectiveness with regard to environmental conservation and conduct evaluations of the Group's engagement in environmental initiatives.

As the result of our activities this year, our environmental conservation expenses rose by ¥479 million (about 17% year on year). The primary factor behind this rise in environmental conservation expenses was active R&D investment centered on growth fields declared in the Medium-Term Management Strategy of the Hitachi High-Tech Group.
In FY2017, our environmental conservation expenses were ¥3,303 million, and we made ¥747 million in environmental investment.
Compared with FY2016, environmental conservation expenses increased by ¥479 million and environmental investment rose by ¥146 million.
