YEATS for 2021–2025. The returns for 2019–2025 all give Limassol as port of registry.
Its 91,981 t of CO₂ for 2025 is 3.1 times the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 771.6 kg CO₂, 1.6 times the type median of 467.6 kg. It logged 5,971 hours at sea against a median of 4,243 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 7 years with reported emissions, the highest was 2024 (93,195 t) and the lowest 2020 (73,763 t). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 17.0% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 1.3% and CO₂ per nautical mile fell 3.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
