Carbon Emissions Cruise Ships

This will be made.

Carbon emissions cruise ships. The cruise lines green credentials are also poor and activists accuse them of lagging in efforts to decarbonize. Likewise spending the night on a cruise ship. 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.

Despite improvements in fuel consumption emissions from planes in 2050 are expected to be 7 to 10 times higher than 1990 levels while emissions from ships are projected to increase by 50 to 250. Carić estimates that the average CO2 emissions for a 3000-passenger cruise ship is 1200 kgkm and trips can be thousands of kilometers long. They conclude the carbon footprint of just one large cruise ship can be greater than 12000 cars.

Most packages would also include some air travel to the port of embarkation and back home adding to the overall footprint. Cruise ship emissions make up 02 of all global carbon dioxide emissions from fossil fuel combustion and cement production. The report says that a mid-sized cruise ship can use as much as 150 tonnes of fuel each day which emits as much particulate as one million cars.

Ponants new ship Le Commandant-Charcot sets sail with National Geographic Expeditions in 2021 and will be fitted with a hybrid liquefied natural gas LNG and electric propulsion system. Vast quantities of fuel are required to move the immense mass of a cruise ship with commensurately huge emissions of CO2 as well as nitrogen and sulfur oxides. The emissions dwarf those produced by cars.

The cruise industrys carbon footprint will only increase if it is allowed to operate post-pandemic as it has in the past. Sulphur dioxide emissions from cars was 32m kt versus 62m kt from cruise ships with Carnival accounting for half that the study found. Cruise Lines International Association recently announced a historic global commitment to reduce the rate of carbon emissions across the industry fleet by 40 per cent by 2030.

According to a 2015 report from the ICCT cruise ships account for 6 of marine black carbon emissions despite making up only 1 of ships globally. Emissions from cruise ship engines include nitrogen oxides sulfur.
