| 摘要: |
| 近年来我国冷链物流发展迅速，为迎合节能减排的趋势，量化果蔬冷链对环境的影响，本文采用生命周期评价法分析果蔬冷链生命周期中预冷、贮藏、冷藏运输、销售以及消费等环节的碳足迹，计算每个环节的碳排放因子，并以一条典型某蔬菜冷链为例，量化整个生命周期的碳足迹。结果表明：每千克某蔬菜的冷链碳足迹为0.0413 kg二氧化碳当量，冷藏运输阶段贡献最大，占总量的69%，其次是预冷阶段，占总量的21%。 |

| Abstract: |
| In recent years, China’s cold chain logistics has developed rapidly. To meet the trend of energy saving and emission reduction, and quantify the influence of cold chain on the environment, a life cycle assessment method is used to analyze the carbon footprint of precooling, storage, transportation, sales, and consumption in the cold chain life cycle of fruits and vegetables, and the carbon emission factor for each link is calculated in the paper. A typical vegetable cold chain is taken as an example to quantify the carbon footprint of the entire life cycle. The results show that the cold chain carbon footprint of a vegetable is 0.0413 kg per kilogram of carbon dioxide equivalents. The refrigerated transport stage contributes the most (69%), and it is followed by the precooling stage (21%). |
