ARIANDA 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 24,050 gross tonnage it is larger than 91% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it POLA ILARIA for 2018–2019, BBC PLUTO for 2021–2023 and ARIANDA for 2025. The reported port of registry changed: VALLETTA (2018–2019), then Monrovia (2021–2025).
Its 2,914 t of CO₂ for 2025 is close to 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 238.8 kg CO₂, 2.0 times the type median of 122.2 kg. It logged 1,121 hours at sea against a median of 3,044 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2021 (6,418 t) and the lowest 2019 (1,699 t). Its efficiency percentile within the type went from 37 in 2018 to 79 in 2023 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 2,585 of 3,262 qualifying bulk carriers by EEOI, at the 79th percentile. The dashed line is the type median, 8.0; this vessel reported 11.2.
EEOI divides emissions by transport work, which for this vessel and year was 283,322,292 tonne-miles over 12,398 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 18.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 7.9% and CO₂ per nautical mile fell 6.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
