A NEPITA against its type
Built in 2002, it is 2 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 30,285 gross tonnage it is larger than 68% of the other 470 ro-pax ships with a recorded tonnage. It is one of 27 ro-pax ships here under the France flag, 5.5% of the 493 on the register. The same builder is recorded for 32 other vessels here, 5 of them ro-pax ships. Its MRV returns name it STENA SUPERFAST X for 2018–2019 and A NEPITA for 2020–2025. The reported port of registry changed: Cardiff (2018–2019), then Ajaccio (2020–2025).
Its 40,829 t of CO₂ for 2025 is 36% above the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 569.0 kg CO₂, 22% above the type median of 467.6 kg. It logged 4,682 hours at sea against a median of 4,243 hours for its type that year. 14.3% 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 2018 (57,336 t) and the lowest 2024 (34,184 t). Of the 3 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 28.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 19.4% and CO₂ per nautical mile rose 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
