Abstract

Sustainable urban development necessitates advanced low-carbon transportation strategies, particularly within the cold chain logistics sector, where transporting perishable goods significantly contributes to environmental emissions. This study addresses the gap in empirical research by deploying real-world data from 128 long-haul trips, provided by a logistics company, to develop a comprehensive bottom-up operational-level carbon emission model. Our model quantifies emissions through various operational phases—loading, unloading, and transport—capturing contributions from vehicle operation (driving and idling), refrigeration processes (including transmission, infiltration, and pre-cooling), and refrigerant leakage. It further assesses the impact of ambient temperature on emissions and examines the effectiveness of decarbonization strategies such as employing shore power for pre-cooling and adopting low-carbon refrigerants. Validated against actual fuel consumption with an impressive accuracy of −1.84%, our findings significantly advance green logistics practices, offering practical insights for a transition towards net-zero emissions and improving the sustainability of cold chain transportation systems.

量化冷链运输中的碳排放：现实世界数据驱动的方法

可持续的城市发展需要先进的低碳运输战略，特别是在冷链物流领域，易腐货物的运输对环境排放有很大贡献。本研究通过利用一家物流公司提供的128次长途旅行的真实数据，建立了一个全面的自下而上的运营层面碳排放模型，解决了实证研究中的空白。我们的模型量化了车辆运行（驾驶和空转）、制冷过程（包括传输、渗透和预冷）和制冷剂泄漏等各个操作阶段的排放——装载、卸载和运输捕获。它进一步评估了环境温度对排放的影响，并检查了使用岸电进行预冷和采用低碳制冷剂等脱碳策略的有效性。通过对实际燃料消耗的验证，我们的研究结果具有令人印象深刻的- 1.84%的准确性，显著推进了绿色物流实践，为向净零排放过渡和提高冷链运输系统的可持续性提供了实际见解。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
