Environmental Accounting (Japan)

TDK has historically monitored both the cost of its environmental protection efforts and the load its activities place on the environment. In fiscal 2002, to clarify the relationship between load and cost, and to promote more effective environmental measures, TDK introduced environmental accounting for all of its facilities in Japan.
A summary of fiscal 2022 results is given below.

  • * The investment amount for the fiscal year is the amount paid in fiscal 2022.
  • * Equipment depreciation costs (as defined by law) are included as part of environmental conservation, maintenance, and management costs, but personnel costs are not included as they are determined by the number of employees in a given fiscal year.
  • * Only actual benefits are included. Hypothetical impacts (risk-avoidance impact or presumed impact) are not included.

Summary of Fiscal 2022
