  • (*1)
    Substances that qualify as both a PRTR targeted chemical and a VOC are included under "VOCs" only.
  • (*2)
    We used the calorific value conversion factor of 9.97 MJ/kWh specified by the Act on the Rational Use of Energy (Energy Conservation Act) to disclose the value of electricity consumption converted to primary energy, but the method has been changed to use the physical calorimetric conversion factor (3.6 MJ/kWh) from this fiscal year.
  • (*3)
    In line with the improvement in the accuracy of data collection, we have retroactively adjusted these figures.
  • (*4)
    Location-based
  • (*5)
    Figures have been revised due to changes in business areas.
