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

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.
In addition, in order to achieve the goals of Hitachi Environmental Innovation 2050 (1. Achieving a Decarbonized Society 2. Achieving a Resource Efficient Society 3. Achieving a Harmonized Society with Nature),that are the long-term environmental goals shared by the Hitachi Group, we are managing measures and targets through the Environmental Committee and its subcommittees and meetings, and are working to understand the costs of environmental conservation and improve the effects of environmental conservation by implementing these measures and setting targets.

Compared to the serious state of novel coronavirus infection in the previous fiscal year, the number of serious cases and deaths decreased in FY2021 due to the widespread use of vaccination and other such measures. As a result, this was a year that also brought considerable signs of recovery in environmental activities at Hitachi High-Tech, even though they did not match up to pre-pandemic levels.

Production costs for newsletters introducing environmental initiatives, costs of creating and updating websites, costs of afforestation on company campuses, and other such costs of social projects increased significantly by comparison with the previous fiscal year. The increase amounted to ¥168 million in all (an increase of about 5% year on year).

Under environmental investment costs, the round of investment in pollution prevention was completed by FY2020. As a result, this amount showed a decrease of ¥31 million, but we will make further investment as future need arises. As to global warming prevention, there was an increase of ¥25 million over the previous fiscal year in replacement of air conditioning equipment, conversion of lighting to LED, and other such construction work. The result was that environmental investment showed a slight decrease by ¥7 million overall (a decrease of about 2% year on year).
