ACASTOS against its type
It is one of 119 container ships here under the Marshall Islands flag, 3.4% of the 3,495 on the register. The returns for 2024–2025 all give MAJURO as port of registry.
Its 6,065 t of CO₂ for 2025 is 63% 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 298.3 kg CO₂, 45% below the type median of 545.6 kg. It logged 1,681 hours at sea against a median of 3,155 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 921 of 1,838 qualifying container ships by EEOI, at the 50th percentile. The dashed line is the type median, 14.2; this vessel reported 14.3.
EEOI divides emissions by transport work, which for this vessel and year was 424,725,490 tonne-miles over 20,332 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 165.4% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 165.4% and CO₂ per nautical mile rose 2.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
