CRUISE BONARIA against its type
Built in 2000, it is the same age as the median ro-pax ship on this register (build year 2000, 483 vessels with a known build year). At 24,352 gross tonnage it is larger than 52% 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 132 other vessels here, 27 of them ro-pax ships. Its MRV returns name it KNOSSOS PALACE for 2018–2019 and CRUISE BONARIA for 2020–2025. The reported port of registry changed: Heraklion (2019), then Palermo (2020–2025).
Its 42,511 t of CO₂ for 2025 is 41% 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 712.9 kg CO₂, 1.5 times the type median of 467.6 kg. It logged 3,423 hours at sea against a median of 4,243 hours for its type that year. 13.0% 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 2021 (73,347 t) and the lowest 2020 (39,554 t). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 20.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 39.0% and CO₂ per nautical mile fell 9.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
