摘要： 海运作为最重要的运输方式之一，碳排放量超过10 亿t·a-1，而港口碳排放比例占海运总量的 15%以上，减碳需求迫切。采用自下而上的测算方法，基于设备能耗数据，从港口运行全过程切 入，提出涵盖港口陆地活动和船舶停泊两个运行阶段的碳排放测算方法，并以天津港为案例进行实 证分析。计算结果显示，2023 年天津港碳排放量为98.7 万t，其中船舶停泊碳排放占36.5%，柴油设 备为主要排放源。基于设备能耗数据的测算方法与燃料消耗直接计算方法的误差率在3%以内，验 证了方法的可靠性。最后指出，通过优化船舶调度、推广岸电使用(替代辅机发电)及运营优化(如多 式联运、智能物流)等措施可有效降低港口碳排放强度。

Abstract： Maritime transportation, as one of the most critical modes of transportation, generates more than 1 billion metric tons of carbon emissions annually, with ports accounting for over 15% of the total and needing urgent carbon emissions reduction. This paper adopts a bottom-up estimation approach based on equipment energy consumption data and assessment of the entire port operation process. The proposed carbon emissions estimation method covers both port land-based activities and ship berthing operations. Using Tianjin Port as a case study, an empirical analysis is conducted and reveals that the port's carbon emissions in 2023 are 987,000 metric tons. Ship berthing accounts for 36.5% of total carbon emissions and diesel- powered equipment is identified as the primary emission source. The discrepancy between this equipment- based method and direct fuel consumption calculations was within 3%, confirming the reliability of the proposed approach. Finally, the paper highlights that optimizing ship scheduling, promoting the use of shore power (as a substitute for auxiliary engine power generation), and enhancing operations (e.g., multimodal transportation and smart logistics) can effectively reduce the carbon emissions intensity of ports.
