GRAND NEPTUNE against its type
Built in 2006, it is 2 years older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 59,217 gross tonnage it is larger than 54% of the other 571 vehicle carriers with a recorded tonnage. It is one of 177 vehicle carriers here under the Panama flag, 24.8% of the 713 on the register. The same builder is recorded for 102 other vessels here, 50 of them vehicle carriers. The returns for 2018–2025 all give Panama as port of registry.
Its 11,553 t of CO₂ for 2025 is 1.6 times the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 377.9 kg CO₂, 22% above the type median of 309.1 kg. It logged 2,013 hours at sea against a median of 1,639 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 6 years with reported emissions, the highest was 2024 (17,844 t) and the lowest 2018 (2,958 t). Its efficiency percentile within the type went from 81 in 2018 to 70 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 298 of 423 qualifying vehicle carriers by EEOI, at the 70th percentile. The dashed line is the type median, 51.7; this vessel reported 66.9.
EEOI divides emissions by transport work, which for this vessel and year was 172,683,408 tonne-miles over 30,567 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 290.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2024 to 2025, emissions fell 35.3% while distance sailed fell 38.3%and CO₂ per nautical mile rose 4.9%.That points mainly to how much the vessel sailed, rather than the other.
