LEDA 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. The returns for 2020–2025 all give Hong Kong as port of registry.

Its 41,761 t of CO₂ for 2025 is 2.6 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 593.5 kg CO₂, close to the type median of 545.6 kg. It logged 4,507 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 6 years with reported emissions, the highest was 2025 (41,761 t) and the lowest 2020 (9,173 t). Its efficiency percentile within the type went from 51 in 2020 to 54 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 997 of 1,838 qualifying container ships by EEOI, at the 54th percentile. The dashed line is the type median, 14.2; this vessel reported 15.3.

EEOI divides emissions by transport work, which for this vessel and year was 2,724,111,546 tonne-miles over 70,368 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 355.3% higher than in 2020, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 3.5% while distance sailed rose 6.0%and CO₂ per nautical mile fell 2.4%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 42,418 t
Methane (CH₄): 0.67 t
Nitrous oxide (N₂O): 2.41 t
