AS CLEOPATRA against its type

Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 28,372 gross tonnage it is smaller than 65% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 61 other vessels here, 49 of them container ships. Its MRV returns name it AS CLEOPATRA for 2021–2022 and HUTTON for 2023–2025. The reported port of registry changed: ST JOHN'S (2021–2022), then Monrovia (2023–2025).

Its 10,539 t of CO₂ for 2025 is 36% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 378.8 kg CO₂, 31% below the type median of 545.6 kg. It logged 2,636 hours at sea against a median of 3,155 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2024 (15,509 t) and the lowest 2022 (4,860 t). Its efficiency percentile within the type went from 74 in 2021 to 71 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,308 of 1,838 qualifying container ships by EEOI, at the 71st percentile. The dashed line is the type median, 14.2; this vessel reported 21.1.

EEOI divides emissions by transport work, which for this vessel and year was 499,960,152 tonne-miles over 27,825 nautical miles.

Reported CO₂ in 2025 was 31.9% higher than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 32.0% while distance sailed fell 28.2%and CO₂ per nautical mile fell 5.3%.That points mainly to how much the vessel sailed, rather than the other.
