MARSTAL MAERSK against its type
Built in 2014, it is 6 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 194,849 gross tonnage it is larger than 96% 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 reported port of registry changed: copenhagen (2018), then Kobenhavn (2019–2020), then Marstal (2021–2025).
Its 62,498 t of CO₂ for 2025 is 3.8 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 970.3 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 3,855 hours at sea against a median of 3,155 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2021 (82,048 t) and the lowest 2020 (49,957 t). Its efficiency percentile within the type went from 3 in 2018 to 5 in 2025 (lower is more efficient). Of the 7 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 93 of 1,838 qualifying container ships by EEOI, at the 5th percentile. The dashed line is the type median, 14.2; this vessel reported 6.4.
EEOI divides emissions by transport work, which for this vessel and year was 9,826,705,975 tonne-miles over 64,412 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 13.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 22.2% while distance sailed fell 19.1%and CO₂ per nautical mile fell 3.9%.That points mainly to how much the vessel sailed, rather than the other.
