GNV BLU against its type
Built in 1986, it is 14 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 31,910 gross tonnage it is larger than 73% 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 22 other vessels here, 15 of them ro-pax ships. Grandi Navi Veloci is linked to 8 vessels on this register. Its MRV returns name it SNAV ADRIATICO for 2018–2020 and GNV BLU for 2021–2025. The returns for 2018–2025 all give Napoli as port of registry.
Its 29,890 t of CO₂ for 2025 is close to the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 575.9 kg CO₂, 23% above the type median of 467.6 kg. It logged 3,601 hours at sea against a median of 4,243 hours for its type that year. 17.1% 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 2019 (39,560 t) and the lowest 2021 (823 t). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 6.1% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 8.5% and CO₂ per nautical mile rose 7.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
