GULNAK against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 22,458 gross tonnage it is smaller than 85% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 37 bulk carriers here under the Türkiye flag, 0.5% of the 8,138 on the register. The reported port of registry changed: Izmir (2018–2020), then VALLETTA (2021–2022), then İzmir (2023–2025).
Its 1,903 t of CO₂ for 2025 is 41% 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 255.4 kg CO₂, close to the type median of 260.7 kg. It logged 751 hours at sea against a median of 1,200 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2021 (10,839 t) and the lowest 2025 (1,903 t). Its efficiency percentile within the type went from 89 in 2018 to 65 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,094 of 3,241 qualifying bulk carriers by EEOI, at the 65th percentile. The dashed line is the type median, 7.6; this vessel reported 8.7.
EEOI divides emissions by transport work, which for this vessel and year was 219,734,411 tonne-miles over 7,450 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 75.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 52.7% while distance sailed fell 43.6%and CO₂ per nautical mile fell 16.2%.That points mainly to how much the vessel sailed, rather than the other.
