The carbon footprint of a cruise ship refers to the total amount of greenhouse gases produced by the ship over its lifetime. This includes emissions from the ship's engines, as well as from the generation of electricity, heating, and cooling. Cruise ships are known to be major polluters, and their carbon footprint can be significant. For example, a single large cruise ship can emit as much carbon dioxide in a year as 12,000 cars.
There are a number of factors that contribute to the carbon footprint of a cruise ship. These include the size of the ship, the type of fuel used, and the ship's itinerary. Larger ships, ships that use heavier fuels, and ships that travel long distances tend to have a larger carbon footprint.
