PRIMROSE ACE against its type

Built in 2007, it is 1 year older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 59,952 gross tonnage it is larger than 62% of the other 571 vehicle carriers with a recorded tonnage. It is one of 89 vehicle carriers here under the Liberia flag, 12.5% of the 713 on the register. The same builder is recorded for 102 other vessels here, 50 of them vehicle carriers. The returns for 2018–2025 all give MONROVIA as port of registry.

Its 8,807 t of CO₂ for 2025 is 24% above the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 336.0 kg CO₂, close to the type median of 309.1 kg. It logged 1,788 hours at sea against a median of 1,639 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2019 (16,976 t) and the lowest 2021 (2,159 t). Its efficiency percentile within the type went from 26 in 2018 to 93 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 393 of 423 qualifying vehicle carriers by EEOI, at the 93rd percentile. The dashed line is the type median, 51.7; this vessel reported 119.5.

EEOI divides emissions by transport work, which for this vessel and year was 73,725,180 tonne-miles over 26,211 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 44.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions rose 209.0% and CO₂ per nautical mile rose 14.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Total CO₂ equivalent: 8,945 t
Methane (CH₄): 0.14 t
Nitrous oxide (N₂O): 0.51 t
