This paper provides insights into the potential of cold-ironing for the reduction of externalities. External cost derived from the emissions of CO, NO, SO, and PM from berthed ships in the Spanish port system during 2016 are estimated providing a Spain-wide empirical evidence into where the highest externalities exist and where, on a port by port level, the introduction of cold ironing could yield the highest potential on reducing said externalities. The combined overall external costs from both local and global effects of shipping emissions from berthed vessels were between 326 and 440 million Euro. Eco-efficiency parameters are also obtained. It is found that the population in the port city as well as the composition of traffic are key factors when the external costs are determined, and they should be considered when the investment decision about where cold ironing should be placed is taken.
本文探讨了冷接电在减少外部性方面的潜力。本研究基于 2016 年停泊在西班牙港口系统的船舶 CO、NO、SO 和 PM 排放所产生的外部成本，提供了西班牙范围内的实证证据，说明哪些地方存在最高的外部性，以及在港口层面上，冷接电的引入在减少这些外部性方面可能具有最大的潜力。停泊船舶的航运排放对本地和全球的综合外部成本在 3.26 亿至 4.4 亿欧元之间。本文还获得了生态效率参数。研究发现，在确定外部成本时，港口城市的人口以及交通构成是关键因素，在决定何处应安装冷接电时应考虑这些因素。
