MV NEPTUNE LEADER against its type

Built in 2008, it is 6 years newer than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 44,412 gross tonnage it is larger than 91% of the other 269 ro-ro ships with a recorded tonnage. It is one of 13 ro-ro ships here under the Panama flag, 4.2% of the 311 on the register. Its MRV returns name it MV NEPTUNE LEADER for 2021–2022 and NEPTUNE LEADER for 2024. The returns for 2021–2024 all give PANAMA as port of registry.

Its 5,086 t of CO₂ for 2024 is 79% below the median of 23,708 t among the 228 ro-ro ships on this register that reported for 2024. Per nautical mile it emitted 247.8 kg CO₂, 24% below the type median of 326.0 kg. It logged 1,363 hours at sea against a median of 5,156 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for ro-ro ships was 4.2%. Across 3 years with reported emissions, the highest was 2024 (5,086 t) and the lowest 2021 (2,191 t).

2021: 2,191 t20212,1912022: 2,288 t20222024: 5,086 t20245,086

Reported CO₂ in 2024 was 132.1% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2022 to 2024, emissions rose 122.3% and CO₂ per nautical mile fell 12.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
