MERIDIAN ACE against its type
Built in 2000, it is 8 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 56,175 gross tonnage it is smaller than 67% of the other 571 vehicle carriers with a recorded tonnage. It is one of 66 vehicle carriers here under the Japan flag, 9.3% of the 713 on the register. The same builder is recorded for 136 other vessels here, 36 of them vehicle carriers. The returns for 2023–2025 all give TOKYO as port of registry.
Its 8,938 t of CO₂ for 2025 is 26% above the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 302.5 kg CO₂, close to the type median of 309.1 kg. It logged 1,774 hours at sea against a median of 1,639 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Its efficiency percentile within the type went from 60 in 2023 to 41 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 173 of 423 qualifying vehicle carriers by EEOI, at the 41st percentile. The dashed line is the type median, 51.7; this vessel reported 46.8.
EEOI divides emissions by transport work, which for this vessel and year was 191,060,924 tonne-miles over 29,546 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.7% higher than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 22.7% while distance sailed rose 24.5%and CO₂ per nautical mile fell 1.4%.That points mainly to how much the vessel sailed, rather than the other.
