Environmental Accounting

The Hitachi High-Tech Group is working to efficiently reduce environmental impact by managing and calculating environmental conservation costs, economic effects, and material effects.

Environmental Accounting

Since fiscal 2001, our group has introduced environmental accounting as a management tool for environmental conservation activities. We examine the effectiveness of environmental conservation outcomes in relation to the costs incurred, and evaluate our group’s initiatives in environmental activities.

In order to achieve the goals of the shared long-term environmental targets of the Hitachi Group, "Hitachi Environmental Innovation 2050" (1. Decarbonization, 2. Circular Economy, and 3. Nature Positive), the Environmental Committee, along with its subordinate subcommittees and meetings, implements measures and manages targets. Through the execution of these measures and the setting of target values, we strive to accurately grasp environmental conservation costs and enhance the effectiveness of environmental conservation.

In fiscal 2024, among the costs within the business site area, environmental conservation costs increased by 748 million yen compared to the previous year. This is due to the installation of air conditioning systems and high-voltage substation equipment, among other factors.

Additionally, for remote environmental education, management activity cost (costs associated with management activities for environmental conservation) increased by 27 million yen compared to the previous year, due to an increase in the number of participants, among other factors.

Regarding environmental investment costs, there was a significant increase of 3,981 million yen due to investments in environmental equipment and management, such as the installation of solar power facilities and the improvement of sewage piping associated with the construction of new manufacturing buildings.
