ALEXANDRA MAERSK against its type
It is one of 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The returns for 2024–2025 all give Copenhagen as port of registry.
Its 64,812 t of CO₂ for 2025 is 4.0 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 708.3 kg CO₂, 30% above the type median of 545.6 kg. It logged 5,505 hours at sea against a median of 3,155 hours for its type that year. 0.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 10 in 2024 to 2 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 30 of 1,838 qualifying container ships by EEOI, at the 2nd percentile. The dashed line is the type median, 14.2; this vessel reported 5.6.
EEOI divides emissions by transport work, which for this vessel and year was 11,511,964,476 tonne-miles over 91,499 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 597.2% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 597.2% while distance sailed rose 629.8%and CO₂ per nautical mile fell 4.5%.That points mainly to how much the vessel sailed, rather than the other.
