WINDSWEPT against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 32,901 gross tonnage it is smaller than 62% 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 WINDSWEPT for 2022–2024 and RIYADH MUKAAB for 2025. The reported port of registry changed: Singapore (2022–2024), then Monrovia (2025).
Its 9,215 t of CO₂ for 2025 is 44% 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 431.2 kg CO₂, 21% below the type median of 545.6 kg. It logged 1,678 hours at sea against a median of 3,155 hours for its type that year. 0.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2023 (20,680 t) and the lowest 2022 (1,001 t). Its efficiency percentile within the type went from 100 in 2023 to 96 in 2024 (lower is more efficient). Of the 3 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 821.0% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 50.6% and CO₂ per nautical mile fell 3.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
