Abstract

We investigate the potential for greenhouse gas (GHG) emission cuts for the Norwegian short-sea (domestic) maritime segments of express boats, offshore support vessels, and aquaculture support vessels in comparison to ferries in Norway. Public procurement conditional on climate-friendly operation is catalyzing a transition to battery-electric operation, where most ferries will be battery-electric or fueled by hydrogen by 2030. The comparison to ferries is performed with the help of a methodology inspired by the multi-attribute utility method, which contains 11 features related to technology, operation, and acceptance. This score is used to adjust the 70% CO2 emission reduction achieved by ferries. Based on this methodology, the CO2 emission reduction potential for express boats, offshore support vessels, and aquaculture support vessels is estimated to be 46%. Consequently, these short-sea shipping segments could reduce CO2 emissions by 0.8 million tonnes from 2017 to 2030, which is equivalent to 1.5% of Norwegian emissions in 2017. Norway's experience indicates that there is a sizable potential for reducing CO2 emissions for public procurement conditional on climate-friendly solutions for short-sea shipping in other shipping nations.

有环境条件的公共采购减少二氧化碳排放:挪威短途海运的案例
与挪威的渡轮相比,我们调查了挪威短途(国内)海上快船、近海支援船和水产养殖支援船的温室气体(GHG)减排潜力。以气候友好型运营为条件的公共采购正在促进向电池电动运营的过渡,到2030年,大多数渡轮将由电池电动或氢燃料驱动。与渡轮的比较是在多属性实用方法的启发下进行的,该方法包含与技术、操作和验收相关的11个特征。该分数用于调整渡轮实现的70%二氧化碳减排。根据该方法,快速船、近海支援船和水产养殖支援船的二氧化碳减排潜力估计为46%。因此,从2017年到2030年,这些短途海运段可以减少80万吨的二氧化碳排放量,相当于挪威2017年排放量的1.5%。挪威的经验表明,在其他航运国家,以气候友好型短途航运解决方案为条件的公共采购中,减少二氧化碳排放的潜力相当大。
