NAVI SUN against its type
Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 21,538 gross tonnage it is smaller than 87% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The same builder is recorded for 90 other vessels here, 68 of them bulk carriers. Its MRV returns name it YUNNAN for 2019 and NAVI SUN for 2024–2025. The reported port of registry changed: HONG KONG (2019), then PANAMA (2024–2025).
Its 5,311 t of CO₂ for 2024 is 1.6 times the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 197.4 kg CO₂, 25% below the type median of 264.0 kg. It logged 2,418 hours at sea against a median of 1,238 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Of the 2 sister ships listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.
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 type2019
Position 1,717 of 3,161 qualifying bulk carriers by EEOI, at the 54th percentile. The dashed line is the type median, 8.1; this vessel reported 8.5.
EEOI divides emissions by transport work, which for this vessel and year was 1,324,665,493 tonne-miles over 53,307 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 52.9% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2019 to 2024, emissions fell 52.9% and CO₂ per nautical mile fell 6.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
