MEGA SERENA against its type
Built in 1987, it is 13 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 39,191 gross tonnage it is larger than 86% of the other 470 ro-pax ships with a recorded tonnage. It is one of 84 ro-pax ships here under the Italy flag, 17.0% of the 493 on the register. The same builder is recorded for 75 other vessels here, one of them a ro-pax ship. Corsica Ferries - Sardinia Ferries is linked to 5 vessels on this register. Its MRV returns name it STENA VISION for 2018–2024 and MEGA SERENA for 2025. The reported port of registry changed: Karlskrona (2018–2020), then Limassol (2021–2024), then Genova (2025).
Its 30,004 t of CO₂ for 2025 is close to the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 639.5 kg CO₂, 37% above the type median of 467.6 kg. It logged 3,408 hours at sea against a median of 4,243 hours for its type that year. 8.0% 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 2021 (59,765 t) and the lowest 2025 (30,004 t). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 46.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 38.5% and CO₂ per nautical mile fell 1.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
