【Notes】As a result of the change in months in each fiscal year, the environmental data and information contained in this report including graphs are as follows.

  • ・Before fiscal 2013: Actuals in 12 months from April to March of the following year
  • ・Fiscal 2014: Actuals for 9 months from April to December + Actuals for January to March 2014 (or estimated value) [Partially overlaps with fiscal 2013]
  • ・After fiscal 2015 : Actuals for 12 months from January to December

Environmental data

(1) Basis for environmental accounting calculations
  • Reporting period: January 1, 2021 to December 31, 2021
  • Scope covered: Kuraray
(2) Environmental conservation cost calculation criteria
  • Depreciation: Straight-line method
  • Standard for allocating costs: In principle, 100% of costs are allocated to individual environmental conservation items. However, a portion of costs is allocated on a pro-rata basis.
(3) Standard for calculating environmental conservation effects
  • Effects are calculated in a simple comparison with the total environmental load of the previous fiscal year and are not adjusted for production volume.
(4) Standard for calculating economic effects (benefits) of environmental conservation measures.
  • Although material effects such as income from recycling are known, benefits are deducted from environmental conservation costs.
