MERMAID ACE against its type
Built in 2010, it is 2 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). It is one of 177 vehicle carriers here under the Panama flag, 24.8% of the 713 on the register. The same builder is recorded for 69 other vessels here, 28 of them vehicle carriers. The returns for 2018–2025 all give PANAMA as port of registry.
Its 4,948 t of CO₂ for 2025 is 30% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 272.4 kg CO₂, 12% below the type median of 309.1 kg. It logged 1,407 hours at sea against a median of 1,639 hours for its type that year. 3.8% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2018 (9,886 t) and the lowest 2023 (1,701 t). Its efficiency percentile within the type went from 28 in 2018 to 36 in 2025 (lower is more efficient). Of the 6 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 153 of 423 qualifying vehicle carriers by EEOI, at the 36th percentile. The dashed line is the type median, 51.7; this vessel reported 44.8.
EEOI divides emissions by transport work, which for this vessel and year was 110,404,284 tonne-miles over 18,163 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions fell 29.9% and CO₂ per nautical mile fell 14.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
