LENA B against its type
Built in 2017, it is 5 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 43,046 gross tonnage it is larger than 70% 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 360 other vessels here, 303 of them bulk carriers. Its MRV returns name it LENA B for 2018–2020, THE PROSPERITY for 2022 and BEAR for 2025. The reported port of registry changed: Douglas (2018–2020), then PANAMA (2022), then Monrovia (2025).
Its 2,739 t of CO₂ for 2022 is 30% below the median of 3,908 t among the 3,902 bulk carriers on this register that reported for 2022. Per nautical mile it emitted 230.1 kg CO₂, 20% below the type median of 288.1 kg. It logged 987 hours at sea against a median of 1,254 hours for its type that year. 0.0% of its 2022 emissions were at berth; the median for bulk carriers was 4.2%. Across 4 years with reported emissions, the highest was 2018 (13,728 t) and the lowest 2020 (2,380 t). Its efficiency percentile within the type went from 6 in 2018 to 16 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 590 of 3,692 qualifying bulk carriers by EEOI, at the 16th percentile. The dashed line is the type median, 8.4; this vessel reported 5.7.
EEOI divides emissions by transport work, which for this vessel and year was 482,177,817 tonne-miles over 11,902 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 80.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2020 to 2022, emissions rose 15.1% while distance sailed rose 33.4%and CO₂ per nautical mile fell 13.7%.That points mainly to how much the vessel sailed, rather than the other.
