Abstract
This study assessed the environmental impact of ship operations using a life-cycle assessment (LCA) based on the IMO 2024 LCA Guidelines and ISO 14040/14044 standards. The case study was a training vessel, and actual fuel consumption data from 2025 were analyzed. The well-to-wake emissions from Bunker-A and Diesel Oil were assessed using GaBi software and the CML-IA methodology. Global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), and ozone depletion potential (ODP) were evaluated. Bunker-A and Diesel Oil contributed 2,065 and 580 tonCO2eq, respectively, to greenhouse gas emissions, totaling 2,645 tonCO2eq. The GWP was dominated by tank-to-wake emissions, whereas the well-to-tank processes contributed approximately 20% of the total. In contrast, the AP, EP, and ODP were predominantly associated with upstream fuel production. These findings demonstrate the applicability of the IMO LCA framework to real ship operations and the importance of considering upstream emissions in fuel selection and regulatory compliance.
