ECO MAESTRO against its type
Built in 2024, it is 16 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 16,242 gross tonnage it is smaller than 81% of the other 3,000 container ships with a recorded tonnage. It is one of 336 container ships here under the Malta flag, 9.6% of the 3,495 on the register. The same builder is recorded for 21 other vessels here, 10 of them container ships. The returns for 2024–2025 all give Valletta as port of registry.
Its 8,887 t of CO₂ for 2025 is 46% 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 179.5 kg CO₂, 67% below the type median of 545.6 kg. It logged 4,676 hours at sea against a median of 3,155 hours for its type that year. 7.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 69 in 2024 to 73 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,338 of 1,838 qualifying container ships by EEOI, at the 73rd percentile. The dashed line is the type median, 14.2; this vessel reported 21.9.
EEOI divides emissions by transport work, which for this vessel and year was 405,434,307 tonne-miles over 49,519 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 121.1% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 121.1% while distance sailed rose 82.0%and CO₂ per nautical mile rose 21.5%.That points mainly to how much the vessel sailed, rather than the other.
