ADELINE against its type

Built in 2012, it is 10 years newer than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 21,020 gross tonnage it is smaller than 51% of the other 269 ro-ro ships with a recorded tonnage. It is one of 52 ro-ro ships here under the Malta flag, 16.7% of the 311 on the register. The returns for 2018–2025 all give Valletta as port of registry.

Its 11,131 t of CO₂ for 2025 is 48% 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 222.8 kg CO₂, 32% below the type median of 327.0 kg. It logged 3,907 hours at sea against a median of 4,872 hours for its type that year. 6.4% 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 2019 (17,884 t) and the lowest 2022 (10,027 t). Its efficiency percentile within the type went from 64 in 2018 to 96 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 5.0% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 1.3% and CO₂ per nautical mile fell 3.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
