ARIANA A against its type
Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 27,915 gross tonnage it is smaller than 66% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Marshall Islands flag, 3.4% of the 3,495 on the register. The same builder is recorded for 1 other vessel here, also a container ship. Its MRV returns name it ARIANA A for 2023–2024 and ELISABETH P. for 2025. The returns for 2023–2025 all give MAJURO as port of registry.
Its 21,979 t of CO₂ for 2025 is 34% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 392.2 kg CO₂, 28% below the type median of 545.6 kg. It logged 4,617 hours at sea against a median of 3,155 hours for its type that year. 3.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2024 (23,562 t) and the lowest 2023 (6,836 t). Its efficiency percentile within the type went from 70 in 2023 to 66 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,219 of 1,838 qualifying container ships by EEOI, at the 66th percentile. The dashed line is the type median, 14.2; this vessel reported 19.0.
EEOI divides emissions by transport work, which for this vessel and year was 1,156,200,947 tonne-miles over 56,046 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 221.5% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 6.7% while distance sailed fell 2.3%and CO₂ per nautical mile fell 4.5%.That points mainly to how efficiently it sailed, rather than the other.
