GMB ALCMENE against its type
Built in 2009, it is 2 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 35,240 gross tonnage it is larger than 97% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 146 general cargo ships here under the Bahamas flag, 4.7% of the 3,081 on the register. Its MRV returns name it GMB ALCMENE for 2018–2019, GREAT WOODS for 2021 and LARCH ARROW for 2023–2025. The reported port of registry changed: Monrovia (2019–2021), then Nassau (2023–2025).
Its 1,656 t of CO₂ for 2025 is 41% 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 322.5 kg CO₂, 2.6 times the type median of 122.2 kg. It logged 474 hours at sea against a median of 3,044 hours for its type that year. 4.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2021 (7,467 t) and the lowest 2025 (1,656 t). Its efficiency percentile within the type went from 5 in 2018 to 16 in 2021 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021
Position 52 of 326 qualifying general cargo ships by EEOI, at the 16th percentile. The dashed line is the type median, 22.6; this vessel reported 13.1.
EEOI divides emissions by transport work, which for this vessel and year was 572,173,946 tonne-miles over 21,702 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 55.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 14.5% and CO₂ per nautical mile fell 4.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
