STENA BRITANNICA against its type
Built in 2010, it is 10 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 64,039 gross tonnage it is larger than 99% of the other 470 ro-pax ships with a recorded tonnage. It is one of 19 ro-pax ships here under the United Kingdom flag, 3.9% of the 493 on the register. The same builder is recorded for 1 other vessel here. Stena Line is linked to 17 vessels on this register. The returns for 2018–2025 all give Harwich as port of registry.
Its 64,532 t of CO₂ for 2025 is 2.1 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 783.3 kg CO₂, 1.7 times the type median of 467.6 kg. It logged 5,422 hours at sea against a median of 4,243 hours for its type that year. 3.8% 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 (75,218 t) and the lowest 2024 (58,709 t). Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 4.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 9.9% and CO₂ per nautical mile rose 5.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
