LARS MAERSK against its type

Built in 2004, it is 4 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 50,657 gross tonnage it is larger than 52% 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 64 other vessels here, 53 of them container ships. The reported port of registry changed: Kobenhavn (2019), then Sakskobing (2020–2025).

Its 37,713 t of CO₂ for 2025 is 2.3 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 531.0 kg CO₂, close to the type median of 545.6 kg. It logged 4,647 hours at sea against a median of 3,155 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2025 (37,713 t) and the lowest 2021 (10,512 t). Its efficiency percentile within the type went from 58 in 2019 to 46 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 836 of 1,838 qualifying container ships by EEOI, at the 46th percentile. The dashed line is the type median, 14.2; this vessel reported 13.1.

EEOI divides emissions by transport work, which for this vessel and year was 2,887,676,876 tonne-miles over 71,029 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 90.2% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 22.4% while distance sailed rose 23.8%and CO₂ per nautical mile fell 1.2%.That points mainly to how much the vessel sailed, rather than the other.
