“…The authors estimated the decrease in fuel consumption and CO2 emissions both in calm water and in waves due to the application of this shortterm measure. Shipowners or ship operators will utilize speed reduction, only if the saved fuel cost is higher than the incurred capital and operating costs [24]. Therefore, it is worthwhile to analyse the critical fuel prices at various speeds to determine the optimal speed.…”

All branches of industry as well as the maritime transport industry are encountering the challenge of reducing greenhouse gas (GHG) emissions to pre-vent hazardous climate change. The ratification of the Paris agreement has set a restrain for global average temperature significantly lower than 2 °C and preferably restrains the growth to 1.5 °C compared to preindustrial levels. Therefore, International Maritime Organization (IMO) has imposed an aim to decrease carbon dioxide (CO2) emissions per transport work by a minimum of 40 % by 2030 and to 70 % by 2050 compared to 2008. IMO has proposed various short-term, mid-term, and long-term measures for accomplishing this aim. Speed reduction i.e., slow steaming is a crucial short-term measure, that can be effortlessly implemented, and does not depend upon any supplementary infrastructure. Even a slight speed reduction will lead to substantial fuel reduction and therefore substantial CO2 abatement considering the hypothesis that ship speed and fuel oil consumption are related with the cubic function. The implementation of slow steaming leads to a larger voyage time and consequently to a larger number of ships to attain yearly transport work constant. Therefore, it is essential to analyse the increase in fuel oil consumption and CO2 emissions due to the larger number of ships engaged in maritime transport. This paper provides an extensive review of slow steaming and GHG abatement potential and points out the disadvantages of its application.

“…Steam turbines can save much more fuel. Using liquefi ed natural gas instead of low sulphur marine gas oil can save up to 49% of CO 2 emissions [10]. The use of non-carbon fuels has the greatest mitigation potential, but has seen the least implementation too far.…”

Efforts to reduce emission of toxic gases into the atmosphere by sea transportation have been consistently carried out by the International Maritime Organisation (IMO) since 2009. IMO has introduced a regime known as energy efficiency design index (EEDI) to monitor and quantify the emission of CO2 because of its global climate impact. A comparison was conducted between trimaran hull forms without and with Axe-Bow on the main-hull with S/L=0.3 and 0.4, as well as a comparison with a monohull of comparable displacement. The CFD method was used to analyse resistance. Overall, the trimaran without the Axe-Bow can decrease resistance by 22.6%, while the trimaran with the axe-bow can reduce resistance by 25.0%. Additionally, this resulted in a 54.8% decrease in EEDI on trimarans without axe-bow and a 55.4% reduction on trimaran equipped with axe-bow when compared to MV Sabuk Nusantara 104. In addition, despite little difference between trimaran with and without axe-bow, the introduction of axe-bow has shown apparent benefits to lower EEDI.

“…Ančić et al provided a case study of using alternative power options to reduce carbon emissions of RO-RO passenger transportation along the Croatian coast of the Adriatic Sea [11]. A case study by Degiuli et al [61] investigated the impact of slow steaming, i.e., sailing at reduced speed, on reducing CO 2 emissions from container ships in the Mediterranean Sea. Finally, Merico et al provided a comparative analysis of the emissions from maritime transportation in four Adriatic-Ionian port-cities: Brindisi and Venice (Italy), Patras (Greece), and Rijeka (Croatia) [62].…”

Carbon emissions generated by the transportation sector represent a large part of total greenhouse gas emissions and are thus subject to various policies and initiatives for emission reduction and the development of sustainable transportation networks. Furthermore, passenger transportation generates a significant amount of emissions within this sector, especially in those countries with large and developed tourist sectors. Examples of such countries are Italy and Croatia, located in the Adriatic region, with a large portion of passengers between them being transported utilizing mainly maritime and/or road transportation modes. A proper analysis of the impact of these transportation mode choices on carbon emissions is essential to enable the selection of the optimal transportation mode for the particular transportation route with respect to the generated emissions. Therefore, this study determines the carbon emissions of the maritime and/or road transportation modes on the existing cross-border passenger transportation routes between Italy and Croatia. For the analysis, the Adriatic region was divided into three sections—the Northern, Middle, and Southern regions—each characterized by specific transportation routes defined by geographical features and distances. The results obtained from this research are presented as total carbon emissions for each transportation mode separately, based on each of three chosen routes in different regions. In addition, a carbon emission comparison between each transportation mode in regard to occupancy rate is performed and presented separately for each chosen route based on its specific distances, transportation means, and features. Finally, by providing an analysis of the existing state, this study can serve as a basis for Italy–Croatia cross-border passenger mobility network modernization and the introduction of new, sustainable, and multimodal transportation routes.
