Chen Wei-wang, Everlight ’ s general manager, explains that when businesses traditionally make an accounting of costs, they calculate for items such as raw materials, equipment, depreciation, personnel, and R & D. Operating costs related to environmental protection are typically concealed under various other headings, making it impossible to calculate the individual environmental costs of a particular product or production line.
永光總經理陳偉望解釋，一般企業在計算成本時的科目分類，大多是原料、設備、折舊、人事、研發等項目，至於環保相關作業的費用，則隱藏在各科目下，因此無法算出某條生產線或單項產品的環保成本。
