MBEYA against its type
Built in 2008, it is 4 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). It is one of 22 bulk carriers here under the Sierra Leone flag, 0.3% of the 8,138 on the register. Its MRV returns name it MBEYA for 2018–2024 and YAMAN for 2025. The reported port of registry changed: Belize City (2018–2020), then Bridgetown (2021–2024), then Freetown (2025).
Its 4,067 t of CO₂ for 2025 is 26% above the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 159.4 kg CO₂, 39% below the type median of 260.7 kg. It logged 3,436 hours at sea against a median of 1,199 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2024 (5,045 t) and the lowest 2022 (1,610 t). Its efficiency percentile within the type went from 89 in 2020 to 95 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 3,079 of 3,241 qualifying bulk carriers by EEOI, at the 95th percentile. The dashed line is the type median, 7.6; this vessel reported 15.5.
EEOI divides emissions by transport work, which for this vessel and year was 263,051,746 tonne-miles over 25,515 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 42.2% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 19.4% while distance sailed fell 16.5%and CO₂ per nautical mile fell 3.5%.That points mainly to how much the vessel sailed, rather than the other.
