ONEGO RIO against its type
Built in 2003, it is 4 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 7,576 gross tonnage it is larger than 57% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 306 general cargo ships here under the Netherlands flag, 9.9% of the 3,081 on the register. The returns for 2018–2025 all give Rotterdam as port of registry.
Its 6,514 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 150.5 kg CO₂, 23% above the type median of 122.2 kg. It logged 3,891 hours at sea against a median of 3,044 hours for its type that year. 4.5% 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 2022 (9,051 t) and the lowest 2024 (5,015 t). Its efficiency percentile within the type went from 46 in 2022 to 67 in 2023 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 221 of 331 qualifying general cargo ships by EEOI, at the 67th percentile. The dashed line is the type median, 21.1; this vessel reported 26.1.
EEOI divides emissions by transport work, which for this vessel and year was 215,355,198 tonne-miles over 34,322 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 5.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 29.9% and CO₂ per nautical mile rose 1.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
