Cruise lines are making continuous and measurable progress in the adoption of environmental technologies and practices.
Cruise Line International Association (CLIA) member ships operating with multi-fuel engines have increased from one ship in 2018 to 30 ships today, with 56 forecast to be in service by year-end 2030. CLIA says European Maritime Safety Agency data shows that across 2018-2025, average fuel consumption per ship reporting fuel and emissions, fell about 18.5% and average CO₂ emissions per ship declined about 19.4.
The number of CLIA-member cruise line ships able to connect to onshore power supply (OPS) has more than tripled since 2018, from 55 ships to 193 ships today. Across the fleet of association ships, 249 of them are equipped with advanced wastewater treatment systems. This represents an increase from 136 ships in 2018.
. . . Future Proofing
CLIA ceo president Bud Darr says cruise lines are building ships capable of using new and lower-emissions energy such as biofuels, alongside a range of other environmental technologies and practices.
“Realising the full potential of those investments will require fuel producers, governments, ports, energy providers, and other stakeholders to help create the conditions for safe, competitively priced renewable and lower-emissions fuels supported by the infrastructure needed to deliver them,” says Darr.
Currently, 40 ports worldwide where cruise ships call, fewer than 3%, have at least one cruise berth with OPS, adds CLIA.
