商业宣传册印刷品碳足迹计算方法

Methodology Analysis on Carbon Footprint Calculation for Commercial Brochures

目的研究商业宣传册印刷品的碳足迹具体计算方法与步骤,提出现阶段在计算印刷产品碳足迹中存在的难题与解决方案,给国内商业印刷品或出版印刷品的碳足迹计算提供参考,确定节能减"碳"关键控制点,促进国内印刷工业的可持续发展。方法结合商业印刷企业的实际生产数据,以大卖场宣传册为例进行印刷品碳足迹量化研究。结果得出宣传册从原材料到成品的部分生命周期的碳排放当量,并对影响因素进行了比较分析。结论案例中的单本宣传册碳足迹为0.17 kg,其中纸张碳足迹占55%,其他原材料碳足迹占15%,生产过程碳足迹占22%。

This article studied the method and steps to perform carbon footprint calculation of commercial brochures,and put forward the existing problems in calculating carbon footprint of print products and the corresponding solutions,in order to provide reference for the carbon footprint calculation of commercial brochures or published prints in China,so as to identify the critical control points for reduction of GHG emissions with the purpose of promoting sustainable development of China′s printing industry. In combination with the actual production data of commercial printing enterprises,carbon footprint quantification study of prints was conducted using commercial brochures in shopping malls as an example,and the influencing factors were comparatively analyzed. The case study on the partial life cycle GHG emissions of the sample print product,from raw material acquisition,product manufacture up to the point where the product left the production site,based on calculated CO2 values indicated that the CF of a commercial brochure was 0.17 kg,among which 55% was from paper,15% from other raw materials and 22% from production.
