生命周期视角下食品碳足迹的评估及案例分析

“减排降碳”“碳达峰”“碳中和”已经成为全球气候治理的焦点，作为衡量气候变暖的重要工具，碳足迹可以对食品生命周期内的温室气体排放量进行量化评估，帮助人们提出碳减排的措施。本文从国内外的研究现状出发，以生命周期评价理论为基础，系统阐述碳足迹分析模型和食品产业链排放源，对国内外研究趋势进行可视化分析，并进一步对该领域内面临的挑战、政策环境、消费者购买行为进行讨论，以期为完善我国食品碳足迹标签制度提供借鉴。

Assessment and Case Analysis of Food Carbon Footprint from the Perspective of Life Cycle

“Carbon emission reduction”, “carbon emission peak”, and “carbon neutrality” have become the focus of global climate governance. As an important tool for measuring climate warming, carbon footprint allows for quantification of the carbon footprint of the food life cycle and helps people to propose carbon reduction measures. Beginning with an overview of the current status of research on carbon footprint, this article systematically reviews the carbon footprint analysis model and the food industry chain emission source based on the life cycle assessment theory, makes a visual analysis of the research trends around the world, and discusses the development challenges in the field, policy environment and consumer purchasing behaviors in this field, in order to provide a basis for improving the Chinese food carbon footprint labeling system.
