Decision Framework for Shipowners to Comply with Air Emission Reduction Measures: A Case Study of Methanol as a Fuel

Abstract

The main aim of this chapter is to develop a decision framework for ship owners to comply with emission regulations; various measures that are available to ship owners are analysed. A comparison between technical, operational, and other abatement measures for averting air emissions of carbon equivalent is made. A case study of Methanol as a marine fuel to comply with the air emission regulations is demonstrated. The environmental and economic benefits are evaluated to find the feasibility of alternative fuel technology. The externality will be assessed for the vessel before and after fuel switching. Ranking of different measures available to ship-owners is made by using a Multi Criteria Decision Making Technique. Gaps in the decision framework are analysed and evaluated. In conclusion, a holistic view of the decision framework for ship-owners is given with some recommendations. The case study will prove that, in the long term, by complying with abatement measures or alternative fuel technology, ship owners will avoid carbon tax and will have social and financial benefits. Methanol is a step towards zero emissions and complying with sustainability goals of the United Nations.
