Cruise ships were estimated to have emitted ** million metric tons of carbon dioxide equivalent (MtCOâ‚‚e) in the first three quarters of 2023. In 2019, the global cruise ship fleet produced ** MtCOâ‚‚e. The following year, emissions from these ships plummeted more than ** percent to less than ** MtCOâ‚‚e as a result of COVID-19-related travel restrictions. Emissions remained low the following year, but surged to roughly ** MtCOâ‚‚e in 2022.
