AAL MELBOURNE against its type
Built in 2013, it is 6 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 23,930 gross tonnage it is larger than 90% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The returns for 2018–2025 all give Monrovia as port of registry.
Its 9,876 t of CO₂ for 2025 is 3.5 times 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 287.1 kg CO₂, 2.3 times the type median of 122.2 kg. It logged 2,763 hours at sea against a median of 3,044 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2025 (9,876 t) and the lowest 2022 (1,661 t). Its efficiency percentile within the type went from 90 in 2018 to 24 in 2024 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 77 of 321 qualifying general cargo ships by EEOI, at the 24th percentile. The dashed line is the type median, 23.6; this vessel reported 15.5.
EEOI divides emissions by transport work, which for this vessel and year was 313,372,574 tonne-miles over 16,741 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 141.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, so the series has gaps.
From 2024 to 2025, emissions rose 103.8% and CO₂ per nautical mile fell 0.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
