NANA LEEN against its type

Built in 1995, it is 17 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 17,392 gross tonnage it is smaller than 94% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 22 bulk carriers here under the Sierra Leone flag, 0.3% of the 8,138 on the register. The same builder is recorded for 102 other vessels here, 45 of them bulk carriers.

Its 1,029 t of CO₂ for 2025 is 68% 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 200.1 kg CO₂, 23% below the type median of 260.7 kg. It logged 587 hours at sea against a median of 1,200 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2024 (4,731 t) and the lowest 2019 (769 t). Its efficiency percentile within the type went from 92 in 2018 to 90 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 31.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions fell 78.2% and CO₂ per nautical mile rose 5.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
