MEGASTAR against its type
Built in 2017, it is 17 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 49,000 gross tonnage it is larger than 94% of the other 470 ro-pax ships with a recorded tonnage. It is one of 8 ro-pax ships here under the Estonia flag, 1.6% of the 493 on the register. The same builder is recorded for 11 other vessels here, one of them a ro-pax ship. Tallink is linked to 8 vessels on this register. The returns for 2018–2025 all give Tallinn as port of registry.
Its 45,006 t of CO₂ for 2025 is 50% above the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 482.2 kg CO₂, close to the type median of 467.6 kg. It logged 4,827 hours at sea against a median of 4,243 hours for its type that year. 8.5% 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 2022 (56,191 t) and the lowest 2024 (43,385 t). Of the 5 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 6.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 3.7% and CO₂ per nautical mile rose 4.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
