Evaluation of maritime industry compliance with existing environmental regulations – A benchmarking assessment from energy efficiency perspective

The present study provides an initial mapping process for the maritime industry from an energy and environmental perspective. The methodology follows a three-step evaluation process for assessing energy efficiency. At first, an initial categorization of all existing ship type and volume categories based the applied taxonomy within maritime transport sector is made. Secondly, two key energy performance indicators (EEXI & CII) are described and estimated for each individual vessel category. Lastly, an assessment between the examined KPIs values is performed in order to depict the compliance level of each vessel category with the existing environmental regulations set by the International Maritime Organization (IMO). The results of this paper aim to highlight the alignment of the existing vessel categories with the established environmental regulations and offer a starting point for decision-makers in maritime industry to adopt green shipping energy transition strategies, such as the usage of energy efficiency measures or green alternative fuels
