ONEGO TRADER against its type

Built in 2001, it is 6 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,301 gross tonnage it is smaller than 51% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The returns for 2018–2025 all give Madeira as port of registry.

Its 6,613 t of CO₂ for 2025 is 2.3 times 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 136.0 kg CO₂, 11% above the type median of 122.2 kg. It logged 4,342 hours at sea against a median of 3,044 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2023 (7,261 t) and the lowest 2021 (2,797 t). Its efficiency percentile within the type went from 54 in 2022 to 24 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 116 of 479 qualifying general cargo ships by EEOI, at the 24th percentile. The dashed line is the type median, 29.4; this vessel reported 22.2.

0255075100more efficientless efficientThis vessel: 24th percentile, EEOI 22.2

EEOI divides emissions by transport work, which for this vessel and year was 297,742,458 tonne-miles over 48,620 nautical miles.

Reported CO₂ in 2025 was 0.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 10.5% while distance sailed rose 15.4%and CO₂ per nautical mile fell 4.2%.That points mainly to how much the vessel sailed, rather than the other.
