ELIANA MARINO against its type
Built in 2001, it is 1 year older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 18,265 gross tonnage it is smaller than 62% of the other 269 ro-ro ships with a recorded tonnage. It is one of 16 ro-ro ships here under the Portugal flag, 5.1% of the 311 on the register. The same builder is recorded for 180 other vessels here, 13 of them ro-ro ships. Its MRV returns name it ELIANA MARINO for 2018–2022 and MAYAR for 2023–2025. The reported port of registry changed: Napoli (2018–2022), then Madeira (2023–2025).
Its 15,865 t of CO₂ for 2025 is 26% 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 412.0 kg CO₂, 26% above the type median of 327.0 kg. It logged 3,996 hours at sea against a median of 4,872 hours for its type that year. 5.1% 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 (31,760 t) and the lowest 2023 (12,744 t). Its efficiency percentile within the type went from 75 in 2018 to 48 in 2025 (lower is more efficient). Of the 6 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 92 of 192 qualifying ro-ro ships by EEOI, at the 48th percentile. The dashed line is the type median, 85.3; this vessel reported 84.2.
EEOI divides emissions by transport work, which for this vessel and year was 188,306,350 tonne-miles over 38,509 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 50.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 15.9% while distance sailed rose 15.1%and CO₂ per nautical mile rose 0.8%.That points mainly to how much the vessel sailed, rather than the other.
