JOHANNES MAERSK against its type
Built in 2001, it is 7 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 30,166 gross tonnage it is smaller than 64% 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 35 other vessels here, 26 of them container ships. The returns for 2022–2025 all give Aalborg as port of registry.
Its 21,962 t of CO₂ for 2025 is 34% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 441.2 kg CO₂, 19% below the type median of 545.6 kg. It logged 4,169 hours at sea against a median of 3,155 hours for its type that year. 3.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2025 (21,962 t) and the lowest 2023 (799 t). Its efficiency percentile within the type went from 73 in 2024 to 68 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,249 of 1,838 qualifying container ships by EEOI, at the 68th percentile. The dashed line is the type median, 14.2; this vessel reported 19.6.
EEOI divides emissions by transport work, which for this vessel and year was 1,122,816,973 tonne-miles over 49,781 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 512.3% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 53.5% while distance sailed rose 55.8%and CO₂ per nautical mile fell 1.5%.That points mainly to how much the vessel sailed, rather than the other.
