Eco Trends in Cruise Energy

Transition

Around 360 cruise vessels are operating on the world’s wa- terways today, transporting more than 25 million passengers to new and established locations globally. The recent cruise boom has driven growth, with 93 new vessels now under construction. But the rising popularity of remote and adven- turous routes such as the Polar Regions and UNESCO heri- tage sights have raised concerns about the ? eet’s impact on marine environments and coastlines. Several cruise leaders are working ahead of legislation to incorporate latest tech- nologies and green strategies. Here, we take a brief look at some of the most promising technology available.
