The third annual report emphasises the environmental commitment of CLIA cruise lines.

The cruise industry has made serious waves in implementing sustainable technologies and practices according to the third annual Global Cruise Industry Environmental Technologies and Practices Report compiled by the Cruise Lines International Association (CLIA).

Michael Thamm, chairman of CLIA Europe and group CEO of Costa Group and Carnival Asia, shared the results at Seatrade Europe in Hamburg.

“While cruise ships comprise far less than 1 per cent of the global maritime community, cruise lines are at the forefront in developing responsible tourism practices and innovative technologies. Our industry leads in environmental stewardship,” said Thamm.

“The entire shipping industry benefits from early adoption of innovative technologies by cruise lines—many of which did not exist five to 10 years ago such as exhaust gas cleaning systems (EGCS), LNG as fuel for passenger ships and shore-side power capabilities.”

CLIA cruise lines have invested more than $22 billion in ships with new, energy-efficient technologies and cleaner fuels, and as a result have made substantial progress in these areas:

• LNG fuel: The 2019 report found 44 per cent of new build capacity will rely on LNG fuel for primary propulsion, a 60 per cent increase in overall capacity compared to last year.

• Exhaust gas cleaning systems (EGCS): More than 68 per cent of global capacity utilises EGCS to meet or exceed air emissions requirements representing an increase in capacity of 17 per cent compared to last year. Additionally, 75 per cent of non-LNG new builds will have EGCS installed, an increase in capacity of 8 per cent compared to last year.

• Advanced wastewater treatment systems: 100 per cent of new ships on order are specified to have advanced wastewater treatment systems (an increase of 26 per cent over 2018) and currently 68 per cent of the CLIA cruise lines’ global fleet capacity is served by advanced wastewater treatment systems (an increase of 13 per cent over 2018).

• Shore-side power capability: In port, cruise ships are increasingly equipped with the technology to allow delivery of shoreside electricity, thus allowing engines to be switched off, and there are many collaborations with ports and governments to increase the availability.

• Fleet age: The CLIA fleet is getting younger – the average age of the CLIA cruise lines fleet is 14.1 years compared to 14.6 the previous 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.
