Abstract

The growth of the cruise industry throughout recent years and the changing public opinion on cruise ships has led to increasing concerns regarding the impact cruise vessels have on the world’s climate and environ- ment. Cruise passengers prefer not to be related with heavy polluting vessels. In fact, trends like responsible tourism and sustainable travel are increasing, especially among younger generations. In order to maintain a viable business model, cruise operators are compelled to consider exploring new energy sources and energy carriers to power their cruise vessels. Alternative carbon-neutral fuels are found to be a potential solution. As such, this research aims to evaluate the viability of possible alternative carbon-neutral fuels on board cruise ships.
