COSCO SHIPPING AQUARIUS 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 2019–2025 all give Hong Kong as port of registry.
Its 24,881 t of CO₂ for 2024 is 40% above the median of 17,769 t among the 2,101 container ships on this register that reported for 2024. Per nautical mile it emitted 900.7 kg CO₂, 1.7 times the type median of 528.5 kg. It logged 1,706 hours at sea against a median of 3,325 hours for its type that year. 1.6% of its 2024 emissions were at berth; the median for container ships was 2.8%. Across 3 years with reported emissions, the highest was 2019 (45,744 t) and the lowest 2020 (4,010 t). Its efficiency percentile within the type went from 4 in 2019 to 14 in 2024 (lower is more efficient). Of the 3 comparable vessels listed below with a 2024 return, 3 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 233 of 1,661 qualifying container ships by EEOI, at the 14th percentile. The dashed line is the type median, 15.4; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 3,260,900,393 tonne-miles over 27,625 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 45.6% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2020 to 2024, emissions rose 520.5% while distance sailed rose 384.7%and CO₂ per nautical mile rose 28.0%.That points mainly to how much the vessel sailed, rather than the other.
