MAERSK COLUMBUS against its type

Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 74,642 gross tonnage it is larger than 64% of the other 3,000 container ships with a recorded tonnage. It is one of 69 container ships here under the United Kingdom flag, 2.0% of the 3,495 on the register. The same builder is recorded for 133 other vessels here, 105 of them container ships. The returns for 2018–2025 all give Norfolk as port of registry.

Its 42,708 t of CO₂ for 2025 is 2.6 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 604.1 kg CO₂, 11% above the type median of 545.6 kg. It logged 4,536 hours at sea against a median of 3,155 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2024 (59,908 t) and the lowest 2022 (30,663 t). Its efficiency percentile within the type went from 21 in 2018 to 50 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 916 of 1,838 qualifying container ships by EEOI, at the 50th percentile. The dashed line is the type median, 14.2; this vessel reported 14.2.

EEOI divides emissions by transport work, which for this vessel and year was 3,001,249,473 tonne-miles over 70,693 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 0.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 28.7% while distance sailed fell 20.5%and CO₂ per nautical mile fell 10.3%.That points mainly to how much the vessel sailed, rather than the other.
