MSC MARYLENA against its type
Built in 1998, it is 10 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 25,219 gross tonnage it is smaller than 73% 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 32 other vessels here, 21 of them container ships. MSC Shipmanagement is linked to 109 vessels on this register. Its MRV returns name it MSC MARYLENA for 2018–2022 and MSC MARYLENA II for 2023–2025. The reported port of registry changed: Madeira (2018–2022), then Monrovia (2023–2025).
Its 21,655 t of CO₂ for 2025 is 32% 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 437.3 kg CO₂, 20% below the type median of 545.6 kg. It logged 4,935 hours at sea against a median of 3,155 hours for its type that year. 3.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (31,758 t) and the lowest 2022 (16,463 t). Its efficiency percentile within the type was 89 in both 2018 and 2025. Of the 4 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 1,635 of 1,838 qualifying container ships by EEOI, at the 89th percentile. The dashed line is the type median, 14.2; this vessel reported 36.1.
Across the 102 ranked vessels operated by MSC Shipmanagement, the median percentile is 59. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 599,527,686 tonne-miles over 49,516 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 22.9% while distance sailed rose 17.3%and CO₂ per nautical mile rose 4.8%.That points mainly to how much the vessel sailed, rather than the other.
