Hitachi High-Tech 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 introduced environmental accounting starting in 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 a result of Group activities in the current fiscal year, environmental conservation expenses increased by ¥137 million (about 4% year-on-year). The main factors in this increase were higher depreciation expenses due to investment in environmental facilities, which has been increasing in recent years, and higher management costs (increase in personnel expenses and outsourcing expenses) in conjunction with compliance with environmental laws and regulations.
Environmental investment was down ¥137 million (about 21% year-on-year). The main factors were decreases in large-scale production facility updates and replacement of air conditioning equipment and so on. We expanded environmental conservation measures, which contribute to the heightened effectiveness of environmental conservation. The increases occurred due to promotion of activities for achieving a decarbonized society , realizing a recycling-oriented society, and realizing a society in harmony with nature. These are based on the long-term environmental targets of Hitachi, Ltd., in Hitachi Environmental Innovation 2050 and on the Hitachi High-Tech Group Materiality of "Contributing to a sustainable global environment."
