ATHARA against its type
Built in 2003, it is 3 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 35,736 gross tonnage it is larger than 81% of the other 470 ro-pax ships with a recorded tonnage. It is one of 84 ro-pax ships here under the Italy flag, 17.0% of the 493 on the register. The same builder is recorded for 8 other vessels here, 4 of them ro-pax ships. The returns for 2018–2025 all give Cagliari as port of registry.
Its 51,901 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 747.4 kg CO₂, 1.6 times the type median of 467.6 kg. It logged 4,053 hours at sea against a median of 4,243 hours for its type that year. 12.8% 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 (63,924 t) and the lowest 2021 (38,091 t). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 0.5% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 2.9% and CO₂ per nautical mile fell 7.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
