1.Calculation period

April 1, 2016 to March 31, 2017

2.Calculation range

  • (1)Environmental conservation costs
    Kurita Water Industries, Ltd. : Kurita Global Technology Center, Shizuoka Plant, Yokkaichi Sub-branch, Kameyama Sub-branch, Sakai Sub-branch Domestic Subsidiaries: Head Office of Kurita Chemical Manufacturing Ltd., Mie Plant, Iga Plant, Ooita Plant of Kuritec Service Co., Ltd.
  • (2)Environmental and economic benefits
    The Kurita Group
  • *The calculation range of "environmental preservation cost" accounted for 96% of the Kurita Group’s total CO2 emissions and 94% of the Kurita Group,s total waste generation.

3.Calculation method

  • (1)Calculation is performed according to the Environmental Accounting Guidelines (2005 edition) of the Japanese Ministry of the Environment.
  • (2)Environmental conservation expenses include depreciation of environmental investments made in previous years (on environmentally conscious equipment) and personnel expenses necessary for environmental improvement activities.
  • (3)Items whose environmental effects are difficult to quantify directly are evaluated by estimating the proportion that serves for environmental improvement.
  • (4)Economic benefits are calculated by applying a unit price as of March 2016 for every item of the emission reduction of CO2 and waste.
