SH DIANA against its type
Built in 2023, it is 13 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 2 cruise ships here under the Liberia flag, 1.0% of the 202 on the register. The same builder is recorded for 2 other vessels here, one of them a cruise ship. The reported port of registry changed: Panama (2023), then Monrovia (2024–2025).
Its 4,984 t of CO₂ for 2025 is 84% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 239.1 kg CO₂, 71% below the type median of 821.3 kg. It logged 1,866 hours at sea against a median of 3,133 hours for its type that year. 9.6% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 3 years with reported emissions, the highest was 2024 (5,243 t) and the lowest 2025 (4,984 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 4.9% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.9% and CO₂ per nautical mile rose 1.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
