CONTSHIP SKY against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 9,957 gross tonnage it is smaller than 92% 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 SACHSEN for 2018–2021 and CONTSHIP SKY for 2024–2025. The reported port of registry changed: Monrovia (2018–2019), then Majuro (2021), then MONROVIA (2024–2025).
Its 7,205 t of CO₂ for 2025 is 56% 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 292.4 kg CO₂, 46% below the type median of 545.6 kg. It logged 2,764 hours at sea against a median of 3,155 hours for its type that year. 5.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2025 (7,205 t) and the lowest 2024 (552 t). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 143.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 1,204.1% and CO₂ per nautical mile fell 19.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
