MAERSK CHARLESTON against its type
It is one of 202 container ships here under the Hong Kong flag, 5.8% of the 3,495 on the register. The returns for 2024–2025 all give Hong Kong as port of registry.
Its 32,487 t of CO₂ for 2025 is 2.0 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 757.0 kg CO₂, 39% above the type median of 545.6 kg. It logged 2,679 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 8 in 2024 to 24 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 439 of 1,838 qualifying container ships by EEOI, at the 24th percentile. The dashed line is the type median, 14.2; this vessel reported 8.9.
EEOI divides emissions by transport work, which for this vessel and year was 3,666,732,506 tonne-miles over 42,917 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.8% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 35.8% while distance sailed fell 33.3%and CO₂ per nautical mile fell 3.7%.That points mainly to how much the vessel sailed, rather than the other.
