MAERSK HONG KONG against its type
It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The returns for 2018–2025 all give Singapore as port of registry.
Its 48,105 t of CO₂ for 2025 is 2.9 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 786.9 kg CO₂, 44% above the type median of 545.6 kg. It logged 3,774 hours at sea against a median of 3,155 hours for its type that year. 0.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2024 (65,505 t) and the lowest 2022 (6,972 t). Its efficiency percentile within the type went from 4 in 2018 to 15 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 278 of 1,838 qualifying container ships by EEOI, at the 15th percentile. The dashed line is the type median, 14.2; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 6,312,994,751 tonne-miles over 61,135 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 12.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 26.6% while distance sailed fell 25.9%and CO₂ per nautical mile fell 0.9%.That points mainly to how much the vessel sailed, rather than the other.
