Cruise ships pumped 4 occasions extra dangerous sulphuric gases into the ambiance in Europe than passenger automobiles final 12 months, in keeping with new analysis displaying air high quality is deteriorating regardless of emissions limits and business pledges to go inexperienced.
A complete of 509 tonnes of sulphur oxides had been emitted by the 218 cruise vessels in operation throughout Europe final 12 months, up from 465 tonnes of emissions linked to the business in 2019, the final 12 months of regular exercise earlier than the pandemic, in keeping with a report by local weather foyer group Transport & Setting.
A 0.5 per cent cap on sulphur content material in marine fuels launched in 2020 by the Worldwide Maritime Group has helped to chop sulphur emissions per tonne of gas consumed. However dozens of additional cruise ships have been added to the primary operators’ fleets since 2019, which has elevated whole emissions. That is regardless of passenger volumes in Europe not but rebounding to pre-pandemic ranges.
Sulphur oxides have been confirmed to trigger acid rain and may worsen respiratory situations equivalent to bronchial asthma and emphysema. Barcelona ranks because the worst-affected port metropolis in Europe for sulphur emissions, with a complete of 805 port calls by cruise ships resulting in 18 tonnes of sulphur oxides being launched into the ambiance final 12 months.
The analysis additionally confirmed that since 2019 emissions of nitrous oxides and PM2.5 particulate matter, that are each linked to respiratory ailments and lung most cancers, had elevated by 18 per cent and 25 per cent respectively.
Constance Dijkstra, transport campaigner at Transport & Setting, mentioned the analysis confirmed that main European port cities had been “once more choking on poisonous air air pollution from cruise ships”. She additionally warned that the give attention to bettering air air pollution was “dangerously slipping towards options which can be good for the air however are disastrous for biodiversity and local weather change”.

Though cruise ships account for a fraction of the emissions linked to the broader international transport business, the sector has come beneath hearth from regulators, politicians and activists who’re pushing for it to scrub up its environmental document.
A number of European port cities, together with Palma de Mallorca, Marseille, Dubrovnik and Santorini, have positioned restrictions on the business in recent times. Most notably, Venice banned cruise ships weighing greater than 25,000 tonnes from its lagoon to guard its Unesco world heritage website standing in 2021. Emissions of sulphur oxides fell by 80 per cent in Venice consequently, in keeping with the analysis.
In Barcelona, the outgoing leftwing mayor Ada Colau has led a campaign in opposition to cruise ships and urged the Catalan regional authorities to limit the quantity allowed in its port. All of the contenders to switch her — who’re haggling over potential governing coalitions after an election final month — agree that cruise tourism have to be reformed to do town much less hurt.
Xavier Trias, a pro-business politician who has mentioned “we have to develop in high quality not amount”, is usually more likely to turn into the brand new mayor. He has taken purpose at a specific bugbear: transit cruise ships that cease for just some hours in the midst of their journeys, simply sufficient time for passengers to flock to websites such because the Sagrada Família cathedral and again once more. “They bring about nothing,” he mentioned.
Marie-Caroline Laurent, director-general of cruise commerce group CLIA, mentioned the business was “strongly dedicated to bettering its sustainability”. She mentioned corporations had been adhering to emissions controls and investing in shoreside charging know-how, which removes the necessity for ships to burn gas whereas in port.
Carnival, the world’s largest cruise operator, had the best sulphur emissions of any operator, with its fleet of 63 ships emitting 43 per cent extra sulphur oxides than all of Europe’s passenger automobiles.
The Florida-headquartered firm was fined $20mn in 2019 by US prosecutors over environmental violations. It mentioned it was the one main cruise firm to scale back its greenhouse fuel emissions since 2011 regardless of rising its fleet capability by 30 per cent.
“Whereas we’re extremely pleased with the progress we’ve made to this point, we perceive there’s nonetheless extra work to be achieved,” it added.
However Bryan Comer, head of the Worldwide Council on Clear Transportation’s marine programme, mentioned the business’s efforts to enhance its environmental document had been “abysmal”. “It looks like each step they’ve taken to persuade the general public and shareholders that they’re taking sustainability significantly has really made issues worse,” he added.
The IMO’s sulphur cap led to a rise in the usage of so-called scrubbers, which take away sulphur from the ship’s exhaust by amassing the air air pollution and disposing of it at sea — to the detriment of marine life.
Scrubbers had been additionally behind a major soar in particulate matter emissions from cruise ships, in keeping with Transport & Setting, which has known as for a ban on the cleansing system in sure ports to be prolonged to all European waters.
Campaigner Dijkstra criticised the cruise sector’s technique of utilizing liquefied pure fuel as an alternative of heavy oil gas to scale back air air pollution, as engines fuelled by LNG leak unburned methane — a greenhouse fuel that has a warming influence 80 occasions better than carbon dioxide. Round two-fifths of cruise corporations’ order books are LNG-powered vessels.
As a substitute, the sector ought to give attention to the event of recent gas sources equivalent to hydrogen, mentioned Comer of the ICCT. “The cruise business is one the place you really might spend money on these new applied sciences,” he added. “They need to be defending the individuals on the ports of name, they shouldn’t be charging right into a metropolis and harming individuals with no penalties.”
