S NEPTUNE 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 18,462 gross tonnage it is smaller than 93% 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 returns for 2022–2025 all give PANAMA as port of registry.
Its 4,180 t of CO₂ for 2025 is 29% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 250.5 kg CO₂, close to the type median of 260.7 kg. It logged 1,709 hours at sea against a median of 1,200 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2025 (4,180 t) and the lowest 2024 (999 t). Its efficiency percentile within the type went from 39 in 2022 to 85 in 2025 (lower is more efficient). Of the 5 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 2,748 of 3,241 qualifying bulk carriers by EEOI, at the 85th percentile. The dashed line is the type median, 7.6; this vessel reported 11.3.
EEOI divides emissions by transport work, which for this vessel and year was 368,946,161 tonne-miles over 16,689 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 45.9% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 318.4% while distance sailed rose 196.0%and CO₂ per nautical mile rose 41.4%.That points mainly to how much the vessel sailed, rather than the other.
