Its MRV returns name it BAIE DE SEINE for 2018–2019 and SIRENA SEAWAYS for 2020–2025. The reported port of registry changed: Le Havre (2018–2019), then Klaipeda (2020–2025).
Its 26,387 t of CO₂ for 2025 is 12% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 285.3 kg CO₂, 39% below the type median of 467.6 kg. It logged 5,983 hours at sea against a median of 4,243 hours for its type that year. 9.1% 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 2018 (46,218 t) and the lowest 2022 (23,459 t). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 42.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 1.3% and CO₂ per nautical mile rose 2.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
