BALTIC PRINCESS against its type
Built in 2008, it is 8 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 48,915 gross tonnage it is larger than 94% of the other 470 ro-pax ships with a recorded tonnage. It is one of 18 ro-pax ships here under the Finland flag, 3.7% of the 493 on the register. The same builder is recorded for 23 other vessels here, 14 of them ro-pax ships. Silja Line is linked to 2 vessels on this register. The returns for 2018–2025 all give Mariehamn as port of registry.
Its 60,093 t of CO₂ for 2025 is 2.0 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 602.9 kg CO₂, 29% above the type median of 467.6 kg. It logged 6,809 hours at sea against a median of 4,243 hours for its type that year. 5.3% 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 2019 (69,451 t) and the lowest 2023 (54,020 t). Of the 6 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 0.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.4% and CO₂ per nautical mile fell 1.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
