Do cruise ships emit thousands of tons of greenhouse gases per week?

YES

According to an estimate cited in The Guardian in 2006, the 2,092-passenger Queen Elizabeth II consumes 433 metric tons of fuel a day. As each ton burned emits 3.1 tons of carbon dioxide, the big liner produces 9,396 tons of emissions a week. “Travelling to New York and back on the QEII, in other words, uses almost 7.6 times as much carbon as making the same journey by plane,” environmental advocate George Monbiot told the U.K. newspaper.

The 323 cruise ships operating worldwide account for 0.2% of global emissions.  The average vessel carries 3,000 passengers. Cruises are carbon-intensive due to their use of heavy fuel oil and their need to run 24/7, as they feed and house both passengers and accompanying staff while in port and en route.

Environmental groups have long urged the industry to invest in cleaner fuel sources. A German advocacy group, NABU, argues that ships’ reliance on relatively “dirty” fuel oil means a single ship can have the impact of a million cars. It calls on owners to convert ships to lower-sulfur fuels and install emissions-control technology.

ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
