AP LIBERTAS against its type
It is one of 212 bulk carriers here under the Cyprus flag, 2.6% of the 8,138 on the register. Its MRV returns name it AP LIBERTAS for 2018–2019 and CPT STEFANOS M for 2024–2025. The reported port of registry changed: Valletta (2018–2019), then LIMASSOL (2024–2025).
Its 10,166 t of CO₂ for 2019 is 2.4 times the median of 4,211 t among the 3,264 bulk carriers on this register that reported for 2019. Per nautical mile it emitted 325.5 kg CO₂, 12% above the type median of 290.4 kg. It logged 2,823 hours at sea against a median of 1,454 hours for its type that year. 4.3% of its 2019 emissions were at berth; the median for bulk carriers was 3.9%. Its efficiency percentile within the type went from 1 in 2018 to 28 in 2019 (lower is more efficient).
No EU/EEA voyages were reported for 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2019
Position 876 of 3,161 qualifying bulk carriers by EEOI, at the 28th percentile. The dashed line is the type median, 8.1; this vessel reported 6.5.
EEOI divides emissions by transport work, which for this vessel and year was 1,566,360,555 tonne-miles over 31,227 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2019 was 32.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2018 to 2019, emissions rose 32.5% while distance sailed rose 37.8%and CO₂ per nautical mile fell 3.8%.That points mainly to how much the vessel sailed, rather than the other.
