STENA SCOTIA against its type
Built in 1996, it is 6 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 13,017 gross tonnage it is smaller than 72% of the other 269 ro-ro ships with a recorded tonnage. It is one of 8 ro-ro ships here under the United Kingdom flag, 2.6% of the 311 on the register. The returns for 2018–2021 all give Douglas as port of registry.
Its 1,840 t of CO₂ for 2021 is 93% below the median of 24,634 t among the 231 ro-ro ships on this register that reported for 2021. Per nautical mile it emitted 296.2 kg CO₂, 12% below the type median of 337.9 kg. It logged 421 hours at sea against a median of 4,932 hours for its type that year. 4.8% of its 2021 emissions were at berth; the median for ro-ro ships was 4.5%. Across 4 years with reported emissions, the highest was 2020 (21,854 t) and the lowest 2021 (1,840 t). Its efficiency percentile within the type went from 82 in 2018 to 75 in 2020 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2021 was 90.2% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 91.6% and CO₂ per nautical mile fell 17.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
