BRITANNIA SEAWAYS against its type
Built in 1999, it is 3 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 24,196 gross tonnage it is larger than 62% of the other 269 ro-ro ships with a recorded tonnage. It is one of 21 ro-ro ships here under the Denmark flag, 6.8% of the 311 on the register. The same builder is recorded for 132 other vessels here, 2 of them ro-ro ships. The reported port of registry changed: København (2018–2021), then Kobenhaven (2022), then København (2023–2025).
Its 9,406 t of CO₂ for 2025 is 56% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 510.5 kg CO₂, 1.6 times the type median of 327.0 kg. It logged 1,242 hours at sea against a median of 4,872 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2021 (33,727 t) and the lowest 2025 (9,406 t). Its efficiency percentile within the type went from 73 in 2018 to 90 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 172 of 192 qualifying ro-ro ships by EEOI, at the 90th percentile. The dashed line is the type median, 85.3; this vessel reported 187.3.
EEOI divides emissions by transport work, which for this vessel and year was 50,208,166 tonne-miles over 18,425 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 67.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 70.6% while distance sailed fell 77.2%and CO₂ per nautical mile rose 29.0%.That points mainly to how much the vessel sailed, rather than the other.
