Stakeholder Perspectives on Decarbonization: A Comprehensive Survey of Technology Priorities in the Maritime Industry

Abstract

The maritime industry is a significant contributor to global pollution. Ships emit substantial quantities of greenhouse gases (GHGs) and other pollutants to the air. This paper examines various decarbonisation technologies that have been developed to curb emissions from ships and are being implemented in new designs and existing ships.The adoption of these technologies is a challenge for various stakeholders in the industry.Selecting the right decarbonisation technology for a ship is a multi-criteria decision-making process. This paper aims to do an analysis of these decision-making criteria, attempting to understand thehow various stakeholders arrive at decisions on implementation of the technologies in ships. The criteria studied are Technological maturity, Cost of implementation, GHG reduction potential, Ease of Installation and Maintenance requirements.As part of the research, as survey has been conducted among the selected stakeholders like Shipyards, Ship owners, Ship managers, Designers or consultants and Classification societies or regulatory bodies. An in-depth analysis of the results of a survey is presented with the author’s conclusions.
