STENA NAUTICA against its type
Built in 1986, it is 14 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 11,602 gross tonnage it is smaller than 72% of the other 470 ro-pax ships with a recorded tonnage. It is one of 20 ro-pax ships here under the Sweden flag, 4.1% of the 493 on the register. The same builder is recorded for 3 other vessels here, all of them ro-pax ships. Stena Line is linked to 17 vessels on this register. The returns for 2018–2025 all give Gothenburg as port of registry.
Its 19,648 t of CO₂ for 2025 is 35% 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 5,227 hours at sea against a median of 4,243 hours for its type that year. 8.3% 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 2022 (21,443 t) and the lowest 2019 (19,587 t). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 7.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 1.4% and CO₂ per nautical mile rose 1.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
