BLUE CARRIER 2 against its type
Built in 1997, it is 5 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 23,986 gross tonnage it is larger than 59% of the other 269 ro-ro ships with a recorded tonnage. It is one of 6 ro-ro ships here under the Greece flag, 1.9% of the 311 on the register. Its MRV returns name it CLEMENTINE for 2018–2023 and BLUE CARRIER 2 for 2024–2025. The reported port of registry changed: Antwerp (2018–2021), then Antwerpen (2022–2023), then Piraeus (2024–2025).
Its 22,721 t of CO₂ for 2025 is close to the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 286.4 kg CO₂, 12% below the type median of 327.0 kg. It logged 5,550 hours at sea against a median of 4,872 hours for its type that year. 3.3% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2018 (23,726 t) and the lowest 2024 (15,992 t). Its efficiency percentile within the type went from 50 in 2018 to 81 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 156 of 192 qualifying ro-ro ships by EEOI, at the 81st percentile. The dashed line is the type median, 85.3; this vessel reported 149.3.
EEOI divides emissions by transport work, which for this vessel and year was 152,170,451 tonne-miles over 79,340 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 42.1% while distance sailed rose 39.9%and CO₂ per nautical mile rose 1.6%.That points mainly to how much the vessel sailed, rather than the other.
