Evaluating the impact of the IMO’s Energy Efficiency Design Index: A bibliometric analysis

The term “Energy Efficiency Design Index” (EEDI) was coined by the International Maritime Organisation and was established as one strategy for reducing greenhouse gas emissions from ships. The purpose of this article is to conduct a bibliometric analysis of the research papers published in the past two decades on the implementation process of EEDI. This study utilizes the Scopus database, renowned for its extensive collection of scientific papers. Moreover, to analyse and visualise the data, the bibliometric software tools VOSviewer, Bibliometrix, and Harzing’s Publish or Perish have been used. These tools facilitated the assessment of the research output in this bibliometric study. This article provides insight into research done by scholars globally and shows the contemporary topic trends related to the improvement of EEDI in the maritime world.
