CROWN IRIS against its type
Built in 1992, it is 14 years older than the median passenger ship on this register, which was built in 2006 (127 vessels with a known build year). At 32,396 gross tonnage it is smaller than 59% 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 19 other vessels here, 8 of them passenger ships. Marella Cruises is linked to 3 vessels on this register. The returns for 2019–2025 all give Panama as port of registry.
Its 34,750 t of CO₂ for 2025 is 4.9 times the median of 7,055 t among the 32 passenger ships on this register that reported for 2025. Per nautical mile it emitted 632.4 kg CO₂, 2.5 times the type median of 248.9 kg. It logged 4,100 hours at sea against a median of 2,827 hours for its type that year. 12.2% of its 2025 emissions were at berth; the median for passenger ships was 12.8%. Across 5 years with reported emissions, the highest was 2019 (40,325 t) and the lowest 2023 (28,118 t). Of the 2 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 13.8% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2024 to 2025, emissions rose 20.1% and CO₂ per nautical mile fell 10.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
