ARTEMIS SEAWAYS against its type
It is one of 18 ro-ro ships here under the Türkiye flag, 5.8% of the 311 on the register. Its MRV returns name it UN MARMARA for 2018 and ARTEMIS SEAWAYS for 2019–2025. The returns for 2018–2025 all give Istanbul as port of registry.
Its 36,253 t of CO₂ for 2025 is 1.7 times the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 353.2 kg CO₂, close to the type median of 327.0 kg. It logged 5,995 hours at sea against a median of 4,872 hours for its type that year. 1.0% 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 2021 (47,467 t) and the lowest 2020 (31,734 t). Its efficiency percentile within the type went from 42 in 2018 to 36 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 69 of 192 qualifying ro-ro ships by EEOI, at the 36th percentile. The dashed line is the type median, 85.3; this vessel reported 73.3.
EEOI divides emissions by transport work, which for this vessel and year was 494,587,585 tonne-miles over 102,628 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 16.5% while distance sailed fell 16.2%and CO₂ per nautical mile fell 0.3%.That points mainly to how much the vessel sailed, rather than the other.
