COSCO PORTUGAL against its type
Built in 2014, it is 6 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 153,666 gross tonnage it is larger than 93% 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 returns for 2018–2025 all give Hong Kong as port of registry.
Its 13,424 t of CO₂ for 2025 is 18% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 1,039.2 kg CO₂, 1.9 times the type median of 545.6 kg. It logged 809 hours at sea against a median of 3,155 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2019 (50,924 t) and the lowest 2025 (13,424 t). Its efficiency percentile within the type went from 16 in 2018 to 43 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 795 of 1,838 qualifying container ships by EEOI, at the 43rd percentile. The dashed line is the type median, 14.2; this vessel reported 12.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,079,991,150 tonne-miles over 12,918 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 38.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.
From 2020 to 2025, emissions fell 7.9% while distance sailed fell 28.1%and CO₂ per nautical mile rose 28.0%.
