MAERSK COPENHAGEN against its type
Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 50,869 gross tonnage it is larger than 52% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 983 other vessels here, 86 of them container ships. The returns for 2024–2025 all give Singapore as port of registry.
Its 34,534 t of CO₂ for 2025 is 2.1 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 402.5 kg CO₂, 26% below the type median of 545.6 kg. It logged 6,400 hours at sea against a median of 3,155 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 64 in 2024 to 42 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 766 of 1,838 qualifying container ships by EEOI, at the 42nd percentile. The dashed line is the type median, 14.2; this vessel reported 12.0.
EEOI divides emissions by transport work, which for this vessel and year was 2,877,835,833 tonne-miles over 85,790 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 838.7% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 838.7% while distance sailed rose 772.0%and CO₂ per nautical mile rose 7.6%.That points mainly to how much the vessel sailed, rather than the other.
