This paper gives an overview of scientific challenges that occur when performing life-cycle assessment (LCA) in the food supply chain. In order to evaluate these risks, the Failure Mode and Effect Analysis tool has been used. Challenges related to setting the goal and scope of LCA revealed four hot spots: system boundaries of LCA; used functional units; type and quality of data categories, and main assumptions and limitations of the study. Within the inventory analysis, challenging issues are associated with allocation of material and energy flows and waste streams released to the environment. Impact assessment brings uncertainties in choosing appropriate environmental impacts. Finally, in order to interpret results, a scientifically sound sensitivity analysis should be performed to check how stable calculations and results are. Identified challenges pave the way for improving LCA of food supply chains in order to enable comparison of results.
本文概述了在食品供应链中进行生命周期评估（LCA）时出现的科学挑战。为了评估这些风险，使用了失效模式与效应分析工具。与确定LCA的目标和范围相关的挑战揭示了四个热点：LCA的系统边界；使用的功能单位；数据类别的类型和质量，以及研究的主要假设和局限性。在清单分析中，具有挑战性的问题与物质和能量流的分配以及排放到环境中的废物流有关。影响评估在选择适当的环境影响方面带来了不确定性。最后，为了解释结果，应进行科学合理的敏感性分析，以检查计算和结果的稳定性。识别出的挑战为改进食品供应链的LCA以实现结果比较铺平了道路。
