CARNIVAL FIRENZE against its type
Built in 2020, it is 14 years newer than the median passenger ship on this register, which was built in 2006 (127 vessels with a known build year). At 135,156 gross tonnage it is larger than 86% of the other 117 passenger ships with a recorded tonnage. It is one of 7 passenger ships here under the Panama flag, 5.3% of the 132 on the register. The same builder is recorded for 132 other vessels here, 29 of them passenger ships. Carnival Cruise Line is linked to 18 vessels on this register. Its MRV returns name it COSTA FIRENZE for 2021–2023 and CARNIVAL FIRENZE for 2024. The reported port of registry changed: Genova (2021–2022), then Genoa (2023), then Panama (2024).
Its 22,797 t of CO₂ for 2024 is 2.5 times the median of 9,183 t among the 48 passenger ships on this register that reported for 2024. Per nautical mile it emitted 1,163.3 kg CO₂, 2.5 times the type median of 473.8 kg. It logged 1,170 hours at sea against a median of 1,874 hours for its type that year. 4.8% of its 2024 emissions were at berth; the median for passenger ships was 12.2%. Across 4 years with reported emissions, the highest was 2023 (76,593 t) and the lowest 2024 (22,797 t). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2024 was 51.6% lower than in 2021, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 70.2% and CO₂ per nautical mile rose 0.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
