The 2023 order book data shows that cruise lines continue investment in new vessels with 44 new ships on order during the next five years, representing an investment of $62 billion since 2019. Of these new ships, 25 will be LNG-powered and seven will be either methanol ready on delivery, or methanol capable, representing an investment in new engine technologies that will accelerate the maritime transition towards a future of low to zero carbon fuels.

Examples of progress cited include the number of alternative fuels pilot programs and trials currently in place with cruise ships. In addition, an increasing number of vessels sailing and launching over the next five years will either use alternative fuels or will be able to incorporate zero carbon fuels when they become available. The 2023 report also demonstrates other significant investments cruise lines are making to reduce emissions at berth and at sea, such as shoreside electricity, which allows cruise ships to switch off engines for significant emissions reduction while in port.

More cruise lines are diversifying energy solutions by incorporating multi-fuel engines, trialling fuel cell technology, wind (including solid sail) technology, as well as photovoltaic solutions and battery storage for power shaving.

President, and CEO, CLIA, Kelly Craighead said: “Cruise lines continue to transform the modern fleet to protect the oceans, air and destinations enjoyed by millions of passengers each year. Our data shows a step change in the uptake of new environmental technologies by our cruise line members. Already today cruise lines are building the ships of the future which will run on new, more sustainable engine technologies. The introduction of these new technologies and the many pilot programs and trials in place reveal how the cruise industry is an innovator and early adopter of technologies that are helping us sail to a more sustainable future.”
