Cruise ships in particular are super-emitters of greenhouse gases.

Carbon emissions cruise ships. Environmentalists point out the unsustainable nature of the cheap dream voyages. A number of upcoming ships are opting for cleaner fuel options. Cruise ship in the Giudecca canal Venice.

Even while at dock cruise ships often run dirty diesel engines to provide electrical power to passengers and crew. A 2007 study concluded cruise ships headed for New Zealand were three times more polluting than planes.

According to our calculations a cruiseliner such as Queen Mary 2 emits 043kg of CO2 per passenger mile compared with 0257kg for a long-haul flight even allowing for the further damage of. According to leading independent German pollution analyst Axel Friedrich a single large cruise ship will emit over five tonnes of NOX emissions and 450kg of ultra fine particles a day. Available research suggest that a large cruise ship can have a carbon footprint greater than 12000 cars.

Emissions from cruise ship engines include nitrogen oxides sulfur. They conclude the carbon footprint of just one large cruise ship can be greater than 12000 cars. Carić estimates that the average CO2 emissions for a 3000-passenger cruise ship is 1200 kgkm and trips can be thousands of kilometers long.

The cruise industrys carbon footprint will only increase if it is allowed to operate post-pandemic as it has in the past. While the European Unions Fit for 55 programme will put pressure on passenger ships of all kinds to switch to either emission free fuels or shore power while in port the IMOs Carbon Intensity Index represents a nearer term challenge for cruise ships. Use the myclimate cruise calculator to determine the carbon footprint of your cruise trip as well as the amount that is required for carbon offsetting.

CLIA cruise lines are making an industry-wide emissions commitment to reduce carbon emissions by 40 per cent by 2030 says Harmer.

Note that tourist water transport is much larger than the specific segment of cruise ship tourism analysed here.
