The third annual Global Cruise Industry Environmental Technologies and Practices Report, prepared by Cruise Lines International Association (CLIA), shows improvement on sustainability targets for the industry.
CLIA cruise lines have invested more than US$22bn in energy-efficient technologies and cleaner fuel, with 44% of new-build capacity using liquified natural gas (LNG) fuel for primary propulsion – a 60% increase in capacity powered by LNG fuel over 2018. Cruise Lines have also reduced their emissions through the adoption of exhaust gas cleaning systems (EGCS). More than 68% of global capacity uses EGCS to meet emissions requirements (17% higher than last year), with 75% of non-LNG ship builds having EGCS installed.
The industry has also improved its waste impact on the environment, with 100% of new ships on order fitted to have advanced wastewater treatment (26% more than 2018) and 68% of CLIA cruise lines’ global fleet capacity served by advanced wastewater treatment systems.
More cruise ships are fitted with shoreside electricity technology (30% of global capacity), which allows engines to be switched off, and 88% of new-builds are either already committed to being fitted with shore-side electricity or will be reconfigured to add shore-side power in future. An additional 18% of existing capacity is to be retrofitted with shoreside electricity. Only 16 ports visited by CLIA cruise lines globally can currently support shore-side power, most in North America as well as the ports of Kristiansand (Norway), Hamburg (Germany), and Shanghai (China); however efforts are underway to increase that number.
“While cruise ships comprise far less than 1% of the global maritime community, cruise lines are at the forefront in developing responsible tourism practices and innovative technologies,” said Michael Thamm, chairman of CLIA Europe and group CEO of Costa Group and Carnival Asia. “Our industry leads in environmental stewardship. The entire shipping industry benefits from early adoption of innovative technologies by cruise lines – many of which did not exist 5-10 years ago, such as exhaust gas cleaning systems, LNG as fuel for passenger ships and shore-side power capabilities.”
The CLIA fleet is also getting younger, with the average age of the CLIA cruise lines fleet now 14.1 years, compared to 14.6 last year.
“CLIA cruise lines are passionate about clean oceans and committed to responsible tourism practices and the highest standards of environmental stewardship – with policies and practices often exceeding those required by law,” said Adam Goldstein, chairman of CLIA Global and vice chairman of Royal Caribbean Cruises. “While we are encouraged by and proud of the progress we’ve made, we know there is still work to be done. The cruise industry is a pioneer in maritime environmental protection and has made a fleet-wide commitment to reduce the rate of carbon emissions by 40% by 2030 compared to 2008. It’s a challenging goal, but the CLIA cruise lines fleet is working diligently to meet this aggressive target.”
