竹展开砧板碳足迹计测及构成分析

A carbon footprint assessment and composition analysis of flattened bamboo chopping board

通过对竹展开砧板从原材料、生产到分配(B2B)过程的跟踪调查,采用英国PAS2050产品碳足迹评估标准,一方面计测运输、加工、储存和供应链投入品等所有排放源的二氧化碳排放当量;另一方面计测竹展开砧板产品碳储存效益的大小,综合得到竹展开砧板碳足迹(净碳排放当量),并进一步分析了碳足迹的构成及影响因素。研究表明:1块规格为360 mm×240 mm×17 mm的竹展开砧板的碳足迹为0.168 3 kg二氧化碳当量,其中运输过程碳排放为0.041 7 kg二氧化碳当量,加工过程碳排放为0.180 5 kg二氧化碳当量,附加物隐含碳排放为0.063 3 kg二氧化碳当量;竹展开砧板产品碳储存效益为-0.117 2 kg二氧化碳当量。

According to the UK PAS2050 product carbon footprint assessment standard,the paper assesses the carbon dioxide emissions of flattened bamboo chopping board＇ s transportation,processing and supply chain inputs and the product＇s efficiency of carbon storage.It gets the footprint （pure carbon equivalent） by putting them together.We get the data through tracking the product＇s life cycle,including the raw materials,the production process and distribution （B2B）.And then,it analyses the composition of carbon footprint and impact factors.The study shows,1 piece of specifications for 360 mm × 240 mm × 17 mm flattered bamboo chopping board＇s carbon footprint is 0.168 3 kg CO2 equivalent.Transportation＇s emission is 0.041 7 kg CO2 equivalent.The production process emission is 0.041 7 kg CO2 equivalent.The addendum＇s emission is 0.063 3 kg CO2 equivalent.1 piece of flattered bamboo chopping board＇s efficiency of carbon storage is-0.117 2 kg CO2 equivalent.
