Hitachi High-Tech GLOBAL

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.

However, the results of the Group's activities in FY2020 were decreased mainly due to a decrease in the number of employees coming to work as a result of COVID-19 pandemic, which led to a decrease in the purchase of consumables, and a reduction in outdoor biodiversity conservation activities, resulting in a decrease in environmental conservation costs of 319 million yen (a decrease of about 9% from the previous year).

Environmental investment also decreased by 207 million yen (about 39 % decreased from the previous year). This was mainly due to the proactive implementation of air-conditioning equipment facility renewal and lighting LED conversion work in FY2019, the previous year.
