WOLF against its type
Built in 2006, it is 1 year older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,581 gross tonnage it is smaller than 57% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 160 general cargo ships here under the Barbados flag, 5.2% of the 3,081 on the register. The same builder is recorded for 127 other vessels here, 52 of them general cargo ships. The reported port of registry changed: Valetta (2018–2022), then Bridgetown (2023–2025).
Its 3,113 t of CO₂ for 2025 is 10% above the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 122.5 kg CO₂, close to the type median of 122.2 kg. It logged 3,898 hours at sea against a median of 3,044 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2022 (3,687 t) and the lowest 2020 (1,445 t). Its efficiency percentile within the type went from 51 in 2018 to 62 in 2022 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 250 of 406 qualifying general cargo ships by EEOI, at the 62nd percentile. The dashed line is the type median, 23.3; this vessel reported 28.1.
EEOI divides emissions by transport work, which for this vessel and year was 130,965,542 tonne-miles over 24,436 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 11.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 59.4% and CO₂ per nautical mile rose 14.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
