AKOMENA against its type
Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Its MRV returns name it AKOMENA for 2018–2023 and GEMINI CAPO for 2024–2025. The reported port of registry changed: Valetta (2021), then Valletta (2022–2023), then MONROVIA (2024), then Majuro (2025).
Its 3,679 t of CO₂ for 2025 is 30% 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 97.6 kg CO₂, 20% below the type median of 122.2 kg. It logged 4,191 hours at sea against a median of 3,044 hours for its type that year. 3.9% 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 2023 (4,236 t) and the lowest 2018 (1,088 t). Its efficiency percentile within the type went from 26 in 2019 to 21 in 2020 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2020
Position 58 of 270 qualifying general cargo ships by EEOI, at the 21st percentile. The dashed line is the type median, 23.3; this vessel reported 16.0.
EEOI divides emissions by transport work, which for this vessel and year was 148,087,610 tonne-miles over 23,591 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 238.0% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 204.2% and CO₂ per nautical mile fell 12.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
