Environmental protection costs

Environmental accounting review for fiscal 2015:
For the Toyo Tires Group overall, in comparison with the previous fiscal year, the amount of investment decreased while the amount of costs increased.

Costs of air pollution preventive measures and wastewater treatment facilities improvement (within business area costs) accounted for the largest portion of the total environment-related expenses. A large amount of money is spent on R&D on a continuous basis.

  • Calculations conform to the Environmental Accounting Guidelines (2005 edition) published by the Ministry of the Environment.
  • Depreciation of investments is included in cost.
  • For costs spanning more than one category, only the costs related to environmental protection were included.
  • In cases where environmental protection costs cannot be clearly separated, a proportional calculation was made using the “environmental ratio” considering the degree of reference to the environmental protection efforts.
  • R&D costs include the costs of efforts to develop eco-friendly products and use alternative materials.
  • Personnel expenses were calculated by man-hours and average wages.

Economic effects of environmental protection measures

The economic effects of environmental protection measures amounted to 256 million yen, mainly from cogeneration, fuel switch, energy-saving activities and profits from recycling and the sale of waste.
