  1. Environmental Accounting is a framework for quantitatively measuring and communicating the costs of environmental conservation activities in business activities and the effect gained by those activities by the monetary unit or material quantity. The purpose of this is to efficiently and effectively promote initiatives for environmental conservation while maintaining a good relationship with society.
  2. The total may not match the sum of the individual values due to rounding.
  3. Environmental conservation expenses: FY2021 to FY2022 (covers the domestic NOF Group), FY2023 to FY2025 (covers the NOF Group, including two major overseas affiliates)
