ARIANNA against its type

Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 8,491 gross tonnage it is larger than 60% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 69 general cargo ships here under the Malta flag, 2.2% of the 3,081 on the register. The returns for 2018–2025 all give Valletta as port of registry.

Its 2,056 t of CO₂ for 2025 is 27% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 132.3 kg CO₂, close to the type median of 122.2 kg. It logged 2,269 hours at sea against a median of 3,044 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2024 (2,915 t) and the lowest 2020 (1,447 t). Its efficiency percentile within the type went from 21 in 2018 to 33 in 2023 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023

Position 109 of 331 qualifying general cargo ships by EEOI, at the 33rd percentile. The dashed line is the type median, 21.1; this vessel reported 15.8.

EEOI divides emissions by transport work, which for this vessel and year was 173,430,284 tonne-miles over 24,361 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 27.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 29.5% and CO₂ per nautical mile rose 11.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
