NAVIA EMERALD 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 51,265 gross tonnage it is larger than 85% 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. Its MRV returns name it TW MANILA for 2020 and NAVIA EMERALD for 2023. The returns for 2020–2023 all give Monrovia as port of registry.
Its 2,432 t of CO₂ for 2023 is 28% below the median of 3,386 t among the 3,573 bulk carriers on this register that reported for 2023. Per nautical mile it emitted 313.0 kg CO₂, 15% above the type median of 272.6 kg. It logged 658 hours at sea against a median of 1,186 hours for its type that year. 3.8% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Its efficiency percentile within the type went from 8 in 2020 to 15 in 2023 (lower is more efficient). Of the 3 comparable vessels listed below with a 2023 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 478 of 3,262 qualifying bulk carriers by EEOI, at the 15th percentile. The dashed line is the type median, 8.0; this vessel reported 5.3.
EEOI divides emissions by transport work, which for this vessel and year was 462,401,141 tonne-miles over 7,770 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 20.3% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2020 to 2023, emissions fell 20.3% while distance sailed rose 7.5%and CO₂ per nautical mile fell 25.8%.That points mainly to how efficiently it sailed, rather than the other.
