This work provides an insight into the external costs associated with ships which had been berthed in four Spanish ports before COVID-19 was on the agenda. Firstly, on a port-by-port level and by individual vessel types, as this can also provide valuable insights. The economic valuation is based on the combination of the significant bottom-up European studies which follow the impact pathway approach (IPA) to calculating costs from transport air emissions. Our results showed higher total external costs for Las Palmas de Gran Canaria (€74.4 m), followed by Tenerife (€20 m), Palma de Mallorca (€19.5 m) and Pasaia (€1.5 m). The external costs by shipping subsectors give more insights into the relationships between ship types and external costs. This has been done to correctly assign the responsibilities among the different shipping sectors inside a port and to better understand the potential benefits of implementing abatement technologies, such as cold ironing. Potential benefits from cold ironing were found to differ hugely among the different ports analysed.
本研究深入探讨了在 COVID-19 成为关注焦点之前停靠在西班牙四个港口的船舶的外部成本。首先，我们按港口和船舶类型逐一进行分析，因为这也可以提供有价值的见解。经济评估基于广泛的欧洲研究，这些研究采用了基于影响路径的方法（IPA）来计算运输空气排放的成本。我们的研究结果表明，大加那利岛拉斯帕尔马斯（€74.4 百万）的外部总成本最高，其次是特内里费岛（€20 百万）、马略卡岛帕尔马（€19.5 百万）和比亚斯（€1.5 百万）。通过航运子行业的外部成本，可以更深入地了解船舶类型和外部成本之间的关系。这样做是为了正确分配港口内不同航运部门的责任，并更好地理解实施减排技术（如冷铁）的潜在好处。研究发现，不同港口之间的冷铁潜在效益差异巨大。
