Addressing the environment, Cruise Lines International Association (CLIA) has published the ‘Global Cruise Industry Environmental Technologies and Practices Inventory and associated Environmental Report’, which was produced by Oxford Economics (OE).
The report, which demonstrates the industry’s commitment to responsible tourism practices and continued progress on the development and implementation of new environmental technologies, was published on the back of CLIA’s ocean-going members committing to get to net carbon neutral cruising by 2050.
“While cruise has been one of the sectors most acutely impacted by the global pandemic, cruise lines remain at the forefront of the challenge to develop new environmental technologies which benefit the entire shipping industry,” said Kelly Craighead, CLIA’s President and CEO (pictured). “Our industry is committed to pursuing net carbon neutral cruising by 2050, and CLIA and our ocean-going members are investing in new technologies and cleaner fuels now to realise this ambition.”
For the first time, the OE Environmental Report addresses the challenge posed by the need for new, alternative fuels and the steps the industry is taking to support progress. Specifically, in addition to LNG, over three-quarters of the global cruise fleet by passenger capacity is now ready to use alternative fuels.
Alternative fuel sources to heavy fuel oils being developed, include biodiesel, methanol, ammonia, hydrogen, and electric batteries.
The report admitted that there were engineering, supply and regulatory hurdles to be overcome before their large-scale adoption can take place, but the cruise industry’s growing investment in new ships is facilitating the research and development of these fuels.
“This report shows that the cruise industry is resilient, innovative and focused on the future,” added Pierfrancesco Vago, Chairman of CLIA Global. “We know that there is more to be done but the cruise industry has shown both its commitment and its capability to rise to the challenge.
“The cruise industry is an enabler of green maritime innovation, which will be the key to de-carbonisation of shipping. This is why CLIA has joined other maritime organisations to propose a $5 bill IMO research and development fund to accelerate the development of zero GHG fuels and propulsion technologies,” he added.
The report claimed that CLIA’s ocean-going cruise line members continued to make substantial progress across a range of areas, including:
1/ Shore-side Power Capability– Cruise lines continue to make significant investments for cruise ships to connect to shoreside electricity, thus allowing engines to be switched off in port.
While significant investment in portside infrastructure will be required, there are many collaborations ongoing between cruise lines, ports and local authorities to increase the availability.
Some 82% of newbuildings is either committed to be fitted with shore-side electricity capability or will be configured to add shore-side power in the future.
Around 35% of global capacity (up 2.3% since 2020) is fitted to operate on shore-side electricity in the 14 ports worldwide where that capability is provided on at least one berth.
2/ LNG Fuel – The report found that 52% of newbuildings will rely on LNG fuel for primary propulsion, a 3% increase in overall capacity, compared to 2020.
3/ Exhaust Gas Cleaning Systems (EGCS) – More than 76% of global capacity utilises EGCS to meet or exceed air emissions requirements, representing an increase in capacity of 7%, compared to 2020.
In addition, 94% of non-LNG newbuildings will have an EGCS installed, in line with already high historical level of investments.
4/ Advanced Wastewater Treatment Systems- Some 100% of new ships on order are to have advanced wastewater treatment systems fitted and currently 74% of the CLIA oceangoing cruise line fleet capacity is using advanced wastewater treatment systems (AWTS) (an increase of 4% over 2020).
Notably, nearly 20% of fleet capacity is equipped with AWTS approved and capable of meeting the nitrogen and phosphorous discharge standards of the IMO MARPOL Annex IV Baltic Sea Special Area
CLIA member cruise lines have committed to a 40% reduction in the rate of carbon emissions across the global fleet by 2030, compared to 2008, consistent with the IMO’s carbon intensity reduction level of ambition, the report said.
