MSC AAYA against its type

Built in 2022, it is 14 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). 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 761 other vessels here, 355 of them container ships. The returns for 2023–2025 all give Monrovia as port of registry.

Its 10,800 t of CO₂ for 2025 is 34% 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 752.8 kg CO₂, 38% above the type median of 545.6 kg. It logged 1,165 hours at sea against a median of 3,155 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2025 (10,800 t) and the lowest 2023 (9,143 t). Its efficiency percentile within the type went from 61 in 2023 to 8 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 18.1% higher than in 2023, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 4.2% while distance sailed rose 6.0%and CO₂ per nautical mile fell 1.7%.That points mainly to how much the vessel sailed, rather than the other.
