AAL MARS 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 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 AAL MARS for 2019–2022 and LILAC ROLLER for 2023–2025. The reported port of registry changed: Monrovia (2019–2022), then Majuro (2023–2025).
Its 13,940 t of CO₂ for 2025 is 4.9 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 290.1 kg CO₂, 2.4 times the type median of 122.2 kg. It logged 3,957 hours at sea against a median of 3,044 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2025 (13,940 t) and the lowest 2019 (2,188 t). Its efficiency percentile within the type went from 83 in 2019 to 97 in 2020 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2020
Position 261 of 270 qualifying general cargo ships by EEOI, at the 97th percentile. The dashed line is the type median, 23.3; this vessel reported 79.2.
EEOI divides emissions by transport work, which for this vessel and year was 83,474,814 tonne-miles over 24,800 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 537.1% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 27.1% and CO₂ per nautical mile fell 1.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
