Abstract

Annual emissions from maritime transport are contributing to the acceleration of global climate change and deteriorating local air quality. Shipowners need information on current and new emission reduction solutions to compare cost-effectiveness and environmental impact. However, emissions reduction in the maritime sector is a complex issue that should also consider the environmental impacts during fuel production and the full impact of different options during use. In this study, different fuel options and emission reduction methods are compared to rank the overall sustainability of alternatives. The overall sustainability assessment is based on the economic and environmental indexes generated, weighted, and aggregated. The results show that the sustainability index of LNG is often the best of the options compared. The difference in fuel prices determines much of the difference in economic performance between fuels. The results emphasize the importance of including several criteria when comparing more sustainable alternatives in shipping.

发展可持续航运和海上运输:减排方法之间的多标准分析

海运每年排放的温室气体加速了全球气候变化，导致当地空气质量恶化。船东需要有关当前和新的减排解决方案的信息，以便比较成本效益和环境影响。然而，海事部门的减排是一个复杂的问题，还应考虑燃料生产过程中的环境影响以及使用过程中不同选择的全面影响。在本研究中，对不同的燃料选择和减排方法进行了比较，对替代方案的整体可持续性进行了排名。总体可持续性评估是基于产生的、加权的和汇总的经济和环境指数。结果表明，LNG的可持续性指标往往是最优的。燃料价格的差异在很大程度上决定了燃料之间经济性能的差异。研究结果强调，在比较航运中更可持续的替代方案时，包括几个标准的重要性。

期刊介绍： The Journal of Engineering for the Maritime Environment is concerned with the design, production and operation of engineering artefacts for the maritime environment. The journal straddles the traditional boundaries of naval architecture, marine engineering, offshore/ocean engineering, coastal engineering and port engineering.
