基于生命周期法的农产品供应链碳足迹分析

    Comparative analysis of carbon footprint of agricultural products supply chain based on life cycle

    • 摘要: 随着经济水平的不断提高和家庭消费水平的持续升级,加快农产品流通的健康发展已经成为当前研究的热点之一。结合生命周期评估方法对农产品不同流通模式的各个环节建立测算模型,并实证分析荔枝供应链的碳足迹。从节省耕地视角,常温流通碳足迹比全程冷链流通的碳足迹要高。对全程冷链流通不同腐损率下碳足迹的变化进行分析,结果发现,腐损率从0上升到18%时,全程冷链流通的碳足迹从2 429.16 kg上升到2 665.15 kg,当全程冷链物流流通的腐损率达到18%时,其碳足迹比常温流通下的碳足迹要高。

       

      Abstract: Currently, researches about rapid and healthy development of agricultural products circulation had drawn a great attention with the sustained growth of economy and upgrade of family consumption. Using the life cycle estimation, this paper constructed carbon measure and calculation models for all the steps of different circulation modes. Specifically, the carbon footprint of litchi supply chain was empirically analyzed from land-saving perspective. And it was found that the carbon footprint with normal temperature circulation was higher than that with cold chain circulation. Moreover, the difference of carbon footprints of the whole cold chain with different decay rates was also analyzed. The results showed that the carbon footprint of the whole cold chain circulation rised from 2 429.16 kg to 2 665.15 kg when the decay rate rised from 0 to 18%, and it was higher than that of the normal temperature circulation when the decay rate of the whole cold chain reached 18%.
