NAVA DIONYSSOS 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 22,432 gross tonnage it is smaller than 85% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 479 bulk carriers here under the Malta flag, 5.9% of the 8,138 on the register. The same builder is recorded for 2 other vessels here, one of them a bulk carrier. Its MRV returns name it IONIC HAWK for 2018–2021 and NAVA DIONYSSOS for 2025. The reported port of registry changed: MAJURO (2018–2021), then Valletta (2025).
Its 2,770 t of CO₂ for 2025 is 14% 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 266.3 kg CO₂, close to the type median of 260.7 kg. It logged 1,003 hours at sea against a median of 1,200 hours for its type that year. 10.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2021 (4,716 t) and the lowest 2018 (1,344 t). Its efficiency percentile within the type went from 78 in 2018 to 80 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 2,579 of 3,241 qualifying bulk carriers by EEOI, at the 80th percentile. The dashed line is the type median, 7.6; this vessel reported 10.4.
EEOI divides emissions by transport work, which for this vessel and year was 267,133,076 tonne-miles over 10,403 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 106.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2021 to 2025, emissions fell 41.3% while distance sailed fell 40.6%and CO₂ per nautical mile fell 1.1%.That points mainly to how much the vessel sailed, rather than the other.
