Calculation of environmental accounts

1. Calculation period: April 1, 2010 to March 31, 2011
2. Calculation range
  • (1)Environmental conservation costs
    Kurita Water Industries, Ltd. : Head Office,Kurita Global Technology Center,Shizuoka Plant,Tsuruga Plant
    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 company of "environmental preservation cost" accounted for 67% and 96% of the Kurita Group's total CO2 emissions and waste generation, respectively.

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.
