MOSEL ACE against its type
Built in 2000, it is 2 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). It is one of 9 ro-ro ships here under the Liberia flag, 2.9% of the 311 on the register. The same builder is recorded for 54 other vessels here. The returns for 2020–2025 all give Monrovia as port of registry.
Its 16,463 t of CO₂ for 2025 is 23% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 282.0 kg CO₂, 14% below the type median of 327.0 kg. It logged 4,855 hours at sea against a median of 4,872 hours for its type that year. 9.4% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 6 years with reported emissions, the highest was 2023 (19,790 t) and the lowest 2020 (15,731 t). Its efficiency percentile within the type went from 93 in 2020 to 70 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 134 of 192 qualifying ro-ro ships by EEOI, at the 70th percentile. The dashed line is the type median, 85.3; this vessel reported 123.1.
EEOI divides emissions by transport work, which for this vessel and year was 133,739,480 tonne-miles over 58,389 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.7% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.9% while distance sailed fell 3.3%and CO₂ per nautical mile fell 0.6%.That points mainly to how much the vessel sailed, rather than the other.
