  • (*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 we have changed the method to disclose the value without conversion to primary energy 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.
  • (*6)
    We used to disclose the primary energy conversion value of electricity consumption in PJ units using the calorific conversion factor specified by the Act on the Rational Use of Energy (Energy Conservation Act), but we have changed the method to disclose the value without primary energy conversion.
