O7 VEGA S against its type
Built in 2011, it is 4 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,351 gross tonnage it is larger than 50% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 381 general cargo ships here under the Antigua and Barbuda flag, 12.4% of the 3,081 on the register. The same builder is recorded for 3 other vessels here, all of them general cargo ships. Its MRV returns name it UNISEA for 2018–2021 and O7 VEGA S for 2023–2025. The reported port of registry changed: Saint John's (2018–2021), then St. John's (2023–2025).
Its 2,208 t of CO₂ for 2025 is 22% below 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 139.7 kg CO₂, 14% above the type median of 122.2 kg. It logged 1,562 hours at sea against a median of 3,044 hours for its type that year. 5.7% 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 2019 (3,648 t) and the lowest 2018 (1,061 t). Its efficiency percentile within the type went from 82 in 2023 to 90 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 289 of 321 qualifying general cargo ships by EEOI, at the 90th percentile. The dashed line is the type median, 23.6; this vessel reported 54.5.
EEOI divides emissions by transport work, which for this vessel and year was 38,614,820 tonne-miles over 15,961 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 108.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 4.9% and CO₂ per nautical mile rose 5.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
