MONACO MAERSK against its type

Built in 2017, it is 9 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 214,286 gross tonnage it is larger than 98% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The same builder is recorded for 660 other vessels here, 231 of them container ships. The returns for 2018–2025 all give Kobenhavn as port of registry.

Its 81,014 t of CO₂ for 2025 is 5.0 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 851.8 kg CO₂, 1.6 times the type median of 545.6 kg. It logged 6,062 hours at sea against a median of 3,155 hours for its type that year. 0.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2025 (81,014 t) and the lowest 2021 (8,288 t). Its efficiency percentile within the type went from 2 in 2018 to 5 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.
