近年来，城市的温室气体清单已经扩大到包括构成城市新陈代谢和经济一部分的边界外活动。本文的重点是估计海港的排放量，这样它们就可以被纳入城市清单的一部分，或者被港口本身用来监测其缓解气候变化的政策和技术改进。我们建议将处理的每吨货物或每名乘客的温室气体排放量指标，以及处理的每件货物价值的排放量指标，作为制定政策和预防排放措施的实际措施，并在一段时间内加以监测。将现有方法应用于巴塞罗那港，我们计算出2008年总共331,390吨温室气体排放（二氧化碳当量），其中一半归因于船舶运动（海上排放），另一半归因于港口、陆地相关活动（陆上排放）。污染最大的是汽车运输船，每吨货物的温室气体排放量为6公斤。了解最高排放者，港口可以采取措施改善港口范围内的船舶活动，例如操纵和酒店。有了这些结果，港口和城市也可以找到减少陆地排放的方法。
In recent years, GHG inventories of cities have expanded to include extra-boundary activities that form part of the city's urban metabolism and economy. This paper centers on estimating the emissions due to seaports, in such a way that they can be included as part of the city's inventory or be used by the port itself to monitor their policy and technology improvements for mitigating climate change. We propose the indicators GHG emissions per ton of cargo handled or per passenger and emissions per value of cargo handled as practical measures for policy making and emission prevention measures to be monitored over time. Adapting existing methodologies to the Port of Barcelona, we calculated a total of 331,390 tons of GHG emissions (CO2equivalents) for the year of 2008, half of which were attributed to vessel movement (sea-based emissions) and the other half to port, land related activities (land-based emissions). The highest polluters were auto carriers with 6kg of GHG emissions per ton of cargo handled. Knowing the highest emitters, the port can take action to improve the ship's activities within the port limits, such as maneuvering and hotelling. With these results, the port and the city can also find ways to reduce the land-based emissions.
