| 生鲜配送高速发展但面临全球低碳减排的巨大压力，降低最后一公里配送环节的碳排放对节能环保和提高经济效益至关重要。选取国内6个典型城市采用全生命周期法分析并评估生鲜配送中蓄冷冰板配送模式和光伏直冷配送模式的碳排放。结果表明：配送箱内设计温度为-5 ℃时，6座城市在光伏直冷模式下生产阶段碳排放均高于蓄冷冰板配送模式下生产阶段碳排放；以生命周期为20 a，各城市光伏直冷配送模式总碳排放相比蓄冷冰板配送模式减少97.95%~98.78%，减排效果更显著，其中蓄冷冰板配送模式下使用阶段碳排放占比最高，光伏直冷配送模式下生产阶段碳排放占比最高，废弃阶段可获得减排效益。当配送箱内设计温度由-5 ℃升至0 ℃时，光伏直冷模式下各城市碳排放减少17.74%~19.31%，蓄冷冰板模式下减少13.21%~18.79%；当配送箱内设计温度由0 ℃升至5 ℃时，光伏直冷模式下各城市碳排放减少17.03%~18.24%，而蓄冷冰板模式下减少15.22%~19.71%。 |

| Abstract: |
| The rapid development of fresh food distribution is facing significant pressure to reduce global carbon emissions. Reducing carbon emissions from last-mile distribution is important for energy conservation, environmental protection, and economic benefits. In this study, six typical cities in China are selected to analyze and evaluate the carbon emissions from ice storage and photovoltaic refrigeration in fresh food distribution using the entire life cycle method. When the design temperature in the delivery box is -5 °C, the results show that the carbon emission of six cities in the production stage for the photovoltaic refrigeration mode is higher than that of the ice storage mode. In the case of a 20-year life cycle, the total carbon emissions of the photovoltaic refrigeration mode in each city were reduced by 97.95%–98.78% compared with the total carbon emissions of the ice storage mode, and the emission reduction effect was significant. Among them, the carbon emissions from the use stage of the ice storage distribution mode contribute the most, and the carbon emissions from the production stage of the photovoltaic refrigeration distribution mode account for the most. Emission reduction benefits can be obtained in the decommissioning stage. When the design temperature in the distribution box increases from -5 °C to 0 °C, the carbon emissions of each city in the photovoltaic refrigeration mode are reduced by 17.74%–19.31%, whereas the carbon emissions in the ice storage mode are reduced by 13.21–18.79%. When the design temperature in the distribution box is increased from 0 °C to 5 °C, the carbon emissions of each city in the photovoltaic refrigeration mode are reduced by 17.03%–18.24%, whereas the carbon emissions in the ice storage mode are reduced by 15.22%–19.71%. |
