RUDOLF against its type
Built in 2010, it is 3 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 8,059 gross tonnage it is larger than 59% 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 16 other vessels here, 12 of them general cargo ships. The reported port of registry changed: St. Johns (2019–2022), then St. John's (2023), then St. Johns (2024–2025).
Its 6,471 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 174.2 kg CO₂, 43% above the type median of 122.2 kg. It logged 3,672 hours at sea against a median of 3,044 hours for its type that year. 2.9% 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 2025 (6,471 t) and the lowest 2023 (2,470 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 460 of 479 qualifying general cargo ships by EEOI, at the 96th percentile. The dashed line is the type median, 29.4; this vessel reported 100.9.
EEOI divides emissions by transport work, which for this vessel and year was 64,134,503 tonne-miles over 37,155 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.4% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 116.5% and CO₂ per nautical mile fell 6.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
