NEPTUNE AEGLI against its type

Built in 2002, it is the same age as the median ro-ro ship on this register (build year 2002, 281 vessels with a known build year). At 21,554 gross tonnage it is larger than 52% of the other 269 ro-ro ships with a recorded tonnage. It is one of 52 ro-ro ships here under the Malta flag, 16.7% of the 311 on the register. The same builder is recorded for 33 other vessels here, 8 of them ro-ro ships. The returns for 2018–2025 all give Valletta as port of registry.

Its 17,741 t of CO₂ for 2025 is 17% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 318.7 kg CO₂, close to the type median of 327.0 kg. It logged 4,652 hours at sea against a median of 4,872 hours for its type that year. 7.3% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2018 (23,375 t) and the lowest 2025 (17,741 t). Its efficiency percentile within the type went from 99 in 2018 to 98 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 188 of 192 qualifying ro-ro ships by EEOI, at the 98th percentile. The dashed line is the type median, 85.3; this vessel reported 275.7.

EEOI divides emissions by transport work, which for this vessel and year was 64,358,086 tonne-miles over 55,668 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 24.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 15.5% while distance sailed fell 12.4%and CO₂ per nautical mile fell 3.5%.That points mainly to how much the vessel sailed, rather than the other.
