ARIADNE against its type
Built in 1996, it is 4 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 30,882 gross tonnage it is larger than 70% of the other 470 ro-pax ships with a recorded tonnage. It is one of 48 ro-pax ships here under the Greece flag, 9.7% of the 493 on the register. The same builder is recorded for 25 other vessels here, 9 of them ro-pax ships. The returns for 2018–2025 all give Piraeus as port of registry.
Its 52,464 t of CO₂ for 2025 is 1.7 times the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 620.6 kg CO₂, 33% above the type median of 467.6 kg. It logged 4,417 hours at sea against a median of 4,243 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 8 years with reported emissions, the highest was 2022 (69,333 t) and the lowest 2021 (33,819 t). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 24.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 18.2% and CO₂ per nautical mile fell 2.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
