At 22,863 gross tonnage it is larger than 85% of the other 2,665 general cargo ships with a recorded tonnage. 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 LA LOUISE for 2022–2024 and LOUISE for 2025. The reported port of registry changed: Monrovia (2022–2024), then Majuro (2025).
Its 3,252 t of CO₂ for 2025 is 15% 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 182.9 kg CO₂, 50% above the type median of 122.2 kg. It logged 2,012 hours at sea against a median of 3,044 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2023 (11,520 t) and the lowest 2025 (3,252 t). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 44 of 406 qualifying general cargo ships by EEOI, at the 11th percentile. The dashed line is the type median, 23.3; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 450,508,380 tonne-miles over 20,044 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 32.8% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 54.2% and CO₂ per nautical mile fell 16.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
