MARDI GRAS against its type
Built in 2020, it is 10 years newer than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). It is one of 67 cruise ships here under the Bahamas flag, 33.2% of the 202 on the register. The same builder is recorded for 11 other vessels here, 8 of them cruise ships. Carnival Cruise Line is linked to 18 vessels on this register.
Its 12,867 t of CO₂ for 2025 is 59% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,279.8 kg CO₂, 1.6 times the type median of 821.3 kg. It logged 590 hours at sea against a median of 3,133 hours for its type that year. 17.4% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.
