ARISTOS II against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 22,927 gross tonnage it is smaller than 83% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 127 bulk carriers here under the Barbados flag, 1.6% of the 8,138 on the register. The same builder is recorded for 461 other vessels here, 43 of them bulk carriers. Its MRV returns name it ARISTOS II for 2020, PENELOPE T for 2021 and LADY KATERINA for 2023–2025. The reported port of registry changed: Monrovia (2021), then Nassau, Bahamas (2023), then Bridgetown (2025).
Its 3,045 t of CO₂ for 2025 is close to the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 312.2 kg CO₂, 20% above the type median of 260.7 kg. It logged 1,219 hours at sea against a median of 1,199 hours for its type that year. 5.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2021 (3,222 t) and the lowest 2020 (1,964 t). Its efficiency percentile within the type went from 90 in 2020 to 97 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 3,152 of 3,241 qualifying bulk carriers by EEOI, at the 97th percentile. The dashed line is the type median, 7.6; this vessel reported 18.2.
EEOI divides emissions by transport work, which for this vessel and year was 167,570,171 tonne-miles over 9,752 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 55.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 1.2% while distance sailed fell 7.4%and CO₂ per nautical mile rose 9.4%.
