MARIT MAERSK against its type

Built in 2015, it is 7 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 182,000 gross tonnage it is larger than 95% of the other 3,000 container ships with a recorded tonnage. The same builder is recorded for 660 other vessels here, 231 of them container ships. The returns for 2018–2025 all give Humlebaek as port of registry.

Its 65,484 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 827.0 kg CO₂, 1.5 times the type median of 545.6 kg. It logged 5,058 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 2024 (96,254 t) and the lowest 2020 (48,254 t). Its efficiency percentile within the type went from 3 in 2018 to 7 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.

Efficiency against its own type2025

Position 125 of 1,838 qualifying container ships by EEOI, at the 7th percentile. The dashed line is the type median, 14.2; this vessel reported 6.6.

EEOI divides emissions by transport work, which for this vessel and year was 9,951,971,125 tonne-miles over 79,184 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 11.3% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 32.0% while distance sailed fell 13.5%and CO₂ per nautical mile fell 21.3%.That points mainly to how efficiently it sailed, rather than the other.
