MAERSK NORFOLK against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 25,888 gross tonnage it is smaller than 70% 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 reported port of registry changed: Copenhagen (2018), then Kobenhavn (2019–2025).
Its 19,366 t of CO₂ for 2025 is 18% 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 319.3 kg CO₂, 41% below the type median of 545.6 kg. It logged 5,024 hours at sea against a median of 3,155 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2021 (21,503 t) and the lowest 2018 (12,728 t). Its efficiency percentile within the type went from 57 in 2018 to 60 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,113 of 1,838 qualifying container ships by EEOI, at the 60th percentile. The dashed line is the type median, 14.2; this vessel reported 17.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,132,540,351 tonne-miles over 60,658 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 52.2% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.9% while distance sailed fell 2.7%and CO₂ per nautical mile fell 1.2%.That points mainly to how much the vessel sailed, rather than the other.
