MAERSK LA PAZ against its type
Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 89,097 gross tonnage it is larger than 69% 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: Hong Kong (2018), then Copenhagen (2025).
Its 24,492 t of CO₂ for 2025 is 50% 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 704.4 kg CO₂, 29% above the type median of 545.6 kg. It logged 2,671 hours at sea against a median of 3,155 hours for its type that year. 1.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 46 in 2018 to 36 in 2025 (lower is more efficient). Of the 5 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 663 of 1,838 qualifying container ships by EEOI, at the 36th percentile. The dashed line is the type median, 14.2; this vessel reported 11.0.
EEOI divides emissions by transport work, which for this vessel and year was 2,234,680,657 tonne-miles over 34,773 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 10.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, 2024, so the series has gaps.
From 2018 to 2025, emissions rose 10.1% while distance sailed rose 23.5%and CO₂ per nautical mile fell 10.9%.That points mainly to how much the vessel sailed, rather than the other.
