LAURA 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 50,688 gross tonnage it is larger than 52% of the other 3,000 container ships with a recorded tonnage. It is one of 202 container ships here under the Hong Kong flag, 5.8% of the 3,495 on the register. The same builder is recorded for 64 other vessels here, 53 of them container ships. Its MRV returns name it LAURA MAERSK for 2019–2021 and LOUIS MAERSK for 2022–2025. The reported port of registry changed: Kobenhavn (2019), then Hvide Sande (2020), then Hong Kong (2021–2025).

Its 40,574 t of CO₂ for 2025 is 2.5 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 579.6 kg CO₂, close to the type median of 545.6 kg. It logged 4,439 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 7 years with reported emissions, the highest was 2025 (40,574 t) and the lowest 2022 (11,542 t). Its efficiency percentile within the type went from 56 in 2019 to 48 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 883 of 1,838 qualifying container ships by EEOI, at the 48th percentile. The dashed line is the type median, 14.2; this vessel reported 13.8.

EEOI divides emissions by transport work, which for this vessel and year was 2,940,176,812 tonne-miles over 70,004 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 110.3% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 6.3% while distance sailed rose 2.2%and CO₂ per nautical mile rose 4.0%.That points mainly to how efficiently it sailed, rather than the other.
