MARTI WIND 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 15,597 gross tonnage it is smaller than 83% 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 WYBELSUM for 2018–2024 and MARTI WIND for 2025. The reported port of registry changed: Gibraltar (2018–2024), then Monrovia (2025).
Its 4,165 t of CO₂ for 2025 is 75% 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 344.2 kg CO₂, 37% below the type median of 545.6 kg. It logged 1,507 hours at sea against a median of 3,155 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (15,078 t) and the lowest 2025 (4,165 t). Its efficiency percentile within the type went from 75 in 2018 to 84 in 2024 (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.

Reported CO₂ by year
Reported CO₂ in 2025 was 71.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 58.6% and CO₂ per nautical mile rose 34.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
