SILJA SERENADE against its type
Built in 1990, it is 10 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 58,376 gross tonnage it is larger than 97% 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 11 other vessels here, one of them a ro-pax ship. Silja Line is linked to 2 vessels on this register. The returns for 2018–2025 all give Mariehamn as port of registry.
Its 50,990 t of CO₂ for 2025 is 1.7 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 571.5 kg CO₂, 22% above the type median of 467.6 kg. It logged 5,870 hours at sea against a median of 4,243 hours for its type that year. 6.7% 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 (58,937 t) and the lowest 2020 (32,243 t). Of the 7 comparable vessels 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 13.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.4% 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.
