BLUE STAR 1 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 29,858 gross tonnage it is larger than 67% 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 22 other vessels here, 15 of them ro-pax ships. The returns for 2018–2025 all give Piraeus as port of registry.
Its 64,662 t of CO₂ for 2025 is 2.2 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 758.8 kg CO₂, 1.6 times the type median of 467.6 kg. It logged 4,243 hours at sea against a median of 4,243 hours for its type that year. 1.6% 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 (86,718 t) and the lowest 2021 (37,821 t). Of the 4 sister ships 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 25.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 10.1% and CO₂ per nautical mile rose 1.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
