CLIA has released its 2023 Global Cruise Industry Environmental Technologies and Practices Report, showing “concrete progress by the sector in advancing its environmental and sustainability agenda”.

According to the report, of the 44 new ships on order during the next five years, 25 will be powered by liquefied natural gas (LNG) and seven will be either methanol ready on delivery, or methanol capable.

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”, a statement said.

The 2023 report also highlights the use shoreside electricity, which allows cruise ships to switch off engines while in port.

Across the CLIA member fleet, 120 ships are equipped to connect to shoreside electricity.

By 2028, more than 210 ships with shoreside power capability are expected to be in use, representing a total of 72 per cent of ships and 74 per cent of global passenger capacity.

Work is also underway to examine fuel cell technology, wind (including solid sail) technology, as well as photovoltaic solutions and battery storage.

In addition, cruise lines are “pursuing fuel flexibility”, investing in propulsion technologies with conversion capabilities.

Cruise ‘on course’ for more sustainable future

CLIA president and CEO 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 programmes 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.”

Earlier this year, CLIA announced the appointment of Sascha Gill as vice-president of sustainability.
