A recent study has identified some of the most polluting cruise ships in the world, likening their carbon dioxide emissions to that of a small town. The analysis of European emissions data conducted by Which? highlighted Disney Cruise Line as the operator of the worst polluting ships.
The study revealed that Disney Dream, the sole Disney vessel in European waters in 2023, emitted an average of 1,481kg of carbon dioxide per nautical mile. Following closely behind, Norwegian Cruise Line was identified as the second-worst polluter, with each of its 10 ships emitting around 1,413kg of carbon dioxide per nautical mile.
Among the top 10 most polluting mega-ships were vessels from Princess Cruises (1,253kg), Royal Caribbean (1,248kg), and MSC Cruises (1,229kg). These findings shed light on the increasing carbon emissions associated with the cruise industry’s popularity.
Disney Cruise Line responded to the study, stating that the methodology used by Which? does not provide a comprehensive view of their operations. They emphasised compliance with air and water quality standards and highlighted their efforts to reduce emissions through the use of environmentally friendly fuels.
According to Which?, a small town typically emits around 93,995 tonnes of carbon dioxide. In comparison, Norwegian Epic alone emitted 95,000 tonnes in 2023, equivalent to the emissions of a town with 20,000 residents. Norwegian Cruise Line committed to reducing greenhouse gas emissions by 25% by 2030, acknowledging the need for sustainability in the industry.
Carbon reduction consultancy Ecollective further highlighted the significant carbon footprint associated with cruising. They pointed out that the carbon emissions from a European cruise can surpass those of a short-haul flight, urging for greater awareness and action to address the environmental impact of cruising.
Naomi Leach, deputy editor of Which? Travel, stressed the importance of transparency and environmental responsibility in the cruise industry. She highlighted the need for more stringent measures to combat greenhouse gas emissions and ensure consumers are informed about the environmental impact of their travel choices.
The study’s findings underscore the pressing need for the cruise industry to adopt sustainable practices and reduce its carbon footprint to mitigate the environmental impact of cruise travel.
