ROYAL NEPTUNE against its type
Built in 2020, it is 8 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 43,500 gross tonnage it is larger than 73% 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 121 other vessels here, 78 of them bulk carriers. The returns for 2020–2025 all give Panama as port of registry.
Its 9,086 t of CO₂ for 2025 is 2.8 times the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 267.5 kg CO₂, close to the type median of 260.7 kg. It logged 2,882 hours at sea against a median of 1,199 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2025 (9,086 t) and the lowest 2023 (1,302 t). Its efficiency percentile within the type went from 48 in 2020 to 14 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 463 of 3,241 qualifying bulk carriers by EEOI, at the 14th percentile. The dashed line is the type median, 7.6; this vessel reported 5.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,778,178,082 tonne-miles over 33,970 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 217.0% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 192.4% while distance sailed rose 168.9%and CO₂ per nautical mile rose 8.8%.That points mainly to how much the vessel sailed, rather than the other.
