AAL KEMBLA against its type
Built in 2011, it is 4 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. Columbia Shipmanagement Ltd. is linked to 43 vessels on this register. The returns for 2018–2025 all give Monrovia as port of registry.
Its 4,097 t of CO₂ for 2025 is 45% above 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 357.4 kg CO₂, 2.9 times the type median of 122.2 kg. It logged 879 hours at sea against a median of 3,044 hours for its type that year. 4.2% 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 2020 (9,278 t) and the lowest 2025 (4,097 t). Its efficiency percentile within the type went from 77 in 2018 to 89 in 2024 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 287 of 321 qualifying general cargo ships by EEOI, at the 89th percentile. The dashed line is the type median, 23.6; this vessel reported 52.4.
Across the 36 ranked vessels operated by Columbia Shipmanagement Ltd., the median percentile is 66. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 87,357,716 tonne-miles over 16,729 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 41.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 10.4% and CO₂ per nautical mile rose 30.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
