NEPTUNE ACE against its type

Built in 2010, it is 2 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 59,006 gross tonnage it is larger than 52% of the other 571 vehicle carriers with a recorded tonnage. It is one of 73 vehicle carriers here under the Bahamas flag, 10.2% of the 713 on the register. The same builder is recorded for 69 other vessels here, 28 of them vehicle carriers. The returns for 2018–2025 all give NASSAU as port of registry.

Its 250 t of CO₂ for 2025 is 96% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 281.1 kg CO₂, close to the type median of 309.1 kg. It logged 111 hours at sea against a median of 1,639 hours for its type that year. 8.2% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2023 (11,086 t) and the lowest 2025 (250 t). Its efficiency percentile within the type went from 65 in 2018 to 56 in 2023 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 95.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 95.9% and CO₂ per nautical mile fell 18.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
