Environmental Accounting

Environmental Conservation Costs

In the fiscal year 2023, the investment amount for environmental conservation decreased by approximately 71 million yen from the previous year to 36.91 million yen, while the cost increased by 7.7 million yen from the previous year to 169.91 million yen. Investments in the fiscal year 2023 continued from the previous year and included the expansion of LED lighting and the replacement of air conditioning equipment with energy-saving models. The main costs were for the recycling of waste, materials and processes, and research and development costs to reduce environmental impact during the manufacturing stage, as well as management costs associated with the operation of EMS activities.
