Its 69,497 t of CO₂ for 2025 is 2.3 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 859.3 kg CO₂, 1.8 times the type median of 467.6 kg. It logged 4,072 hours at sea against a median of 4,243 hours for its type that year. 10.0% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 8 years with reported emissions, the highest was 2025 (69,497 t) and the lowest 2022 (45,037 t). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 40.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 22.3% and CO₂ per nautical mile rose 8.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
