Amid human-caused climate change, cruise lines are doing their part to reduce greenhouse gas emissions and implement other environmentally friendly changes to their vessels. Hurtigruten unveiled its plans to build the
world¡¯s first zero-emission ship, while Royal Caribbean continued building its
most sustainable vessel yet, Icon of the Seas.
In its 2023 Global Cruise Industry Environmental Technologies and Practices Report, Cruise Lines International Association (CLIA) explored
how the cruise industry is getting greener. Many new in-development ships¡ª25 out of 44 set to be delivered within the next five years¡ªwill run on liquified natural gas. Cruise lines are also experimenting with fuel cells, multi-fuel engines, wind technology, photovoltaics and other sustainable technologies.
