VUOKSI MAERSK against its type

Built in 2018, it is 10 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 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The reported port of registry changed: Copenhagen (2018), then Kobenhavn (2019–2025).

Its 16,326 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 368.2 kg CO₂, 33% below the type median of 545.6 kg. It logged 3,400 hours at sea against a median of 3,155 hours for its type that year. 3.4% 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 (21,942 t) and the lowest 2018 (4,563 t). Its efficiency percentile within the type went from 32 in 2018 to 42 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 779 of 1,838 qualifying container ships by EEOI, at the 42nd percentile. The dashed line is the type median, 14.2; this vessel reported 12.2.

EEOI divides emissions by transport work, which for this vessel and year was 1,337,066,339 tonne-miles over 44,334 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 257.8% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 16.3% while distance sailed fell 25.6%and CO₂ per nautical mile rose 12.5%.That points mainly to how much the vessel sailed, rather than the other.
