COSCO SHIPPING ARIES against its type

Built in 2018, it is 10 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 196,670 gross tonnage it is larger than 97% 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 85,693 t of CO₂ for 2025 is 5.2 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 959.6 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 5,517 hours at sea against a median of 3,155 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2020 (94,904 t) and the lowest 2022 (77,214 t). Its efficiency percentile within the type went from 4 in 2018 to 13 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 236 of 1,838 qualifying container ships by EEOI, at the 13th percentile. The dashed line is the type median, 14.2; this vessel reported 7.3.

EEOI divides emissions by transport work, which for this vessel and year was 11,690,735,334 tonne-miles over 89,299 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 3.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.

From 2024 to 2025, emissions fell 6.6% while distance sailed fell 3.2%and CO₂ per nautical mile fell 3.5%.
