KALLIOPI S against its type
Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 23,456 gross tonnage it is smaller than 81% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The same builder is recorded for 180 other vessels here, 74 of them bulk carriers. Its MRV returns name it ORIANA C for 2018–2020 and KALLIOPI S for 2021–2025. The reported port of registry changed: Majuro (2018–2022), then Monrovia (2023–2025).
Its 2,087 t of CO₂ for 2025 is 36% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 301.1 kg CO₂, 15% above the type median of 260.7 kg. It logged 678 hours at sea against a median of 1,200 hours for its type that year. 9.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2022 (6,380 t) and the lowest 2025 (2,087 t). Its efficiency percentile within the type went from 78 in 2018 to 74 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,416 of 3,241 qualifying bulk carriers by EEOI, at the 74th percentile. The dashed line is the type median, 7.6; this vessel reported 9.7.
EEOI divides emissions by transport work, which for this vessel and year was 215,838,676 tonne-miles over 6,932 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 66.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 29.5% while distance sailed fell 32.1%and CO₂ per nautical mile rose 3.7%.That points mainly to how much the vessel sailed, rather than the other.
