Environmental Accounting

We promote efficient environmental management by introducing environmental accounting to clarify the expenses incurred by our sites in Japan for their environmental protection activities.

Environment Maintenance Effectiveness

We calculate the economic effects only for those activities clearly improving our environmental impact.

Type of effectiveness Economic effect
(million yen)
Effects on amounts* Main items
Energy saving 1,177 17,404kL Improvement in productivity; improvement in energy management method
Conservation of resources 66 25,627t Reduction of the amount of materials and resources used
Reduction in waste, and recycling 4,181 7,307t Improvement in recycling rate
Total 5,424
  • *
    "Effects on amounts" indicate the calculated difference with the case where no activities are conducted to improve our environmental impact.
  • *
    No penalties related to the environment have been paid.

The cost for FY2023 is 4,443 and the benefit is 3,900.The cost for FY2024 is 3,789 and the benefit is 4,634. The cost for FY2025 is 3,480 and the benefit is 5,424.

Environmental Accounting Standards

  • 1.
    The sum total of the costs for complying with environment-related laws and regulations, the costs incurred purely for the purpose of improving our environmental impact, and the EMS operation costs are calculated. However, in cases where environmental preservation costs partially overlap the costs for other purposes, the latter shall be deducted and the balance shall be applied.
  • 2.
    Depreciation costs shall be the current fiscal year's depreciation expenses at the environmental conservation facilities.
  • 3.
    If a clear-cut distinction cannot be made between the environmental cost and that for other purposes, if 50% or more of the content is environment-related, the full amount can be counted as the environmental preservation cost.
  • 4.
    The cost-effectiveness by saving energy is yielded from the reduction of either the rated dissipation or the operating time or both.
  • 5.
    The cost-effectiveness by reducing and recycling waste is calculated as follows:
    Lowered costs through reducing waste and recycling =
    [Unit cost of waste treatment in the prior fiscal year (JP¥/ton) – Unit cost of waste treatment in this fiscal year (JP¥/ton)] × Amount of waste generated (tons)
