CONTSHIP ANA against its type
Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,981 gross tonnage it is smaller than 90% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. Its MRV returns name it VEGA OMIKRON for 2018, CONTSHIP ANA for 2021–2023 and MEDKON ANA for 2024–2025. The returns for 2018–2023 all give Monrovia as port of registry.
Its 4,629 t of CO₂ for 2025 is 72% 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 228.7 kg CO₂, 58% below the type median of 545.6 kg. It logged 3,398 hours at sea against a median of 3,155 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2022 (6,439 t) and the lowest 2021 (3,042 t). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 11.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions fell 16.6% and CO₂ per nautical mile fell 39.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
