RONNIE against its type
Built in 2021, it is 14 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 10,000 gross tonnage it is larger than 66% 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 reported port of registry changed: ST. JOHN'S (2021), then St. John´s (2022–2025).
Its 5,781 t of CO₂ for 2025 is 2.1 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 154.8 kg CO₂, 27% above the type median of 122.2 kg. It logged 3,044 hours at sea against a median of 3,044 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2024 (6,810 t) and the lowest 2021 (2,156 t). Its efficiency percentile within the type went from 83 in 2022 to 97 in 2024 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 310 of 321 qualifying general cargo ships by EEOI, at the 97th percentile. The dashed line is the type median, 23.6; this vessel reported 112.6.
EEOI divides emissions by transport work, which for this vessel and year was 60,504,176 tonne-miles over 40,649 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 168.1% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 15.1% and CO₂ per nautical mile fell 7.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
