IOSIF K against its type
Built in 1979, it is 23 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 9,368 gross tonnage it is smaller than 84% 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. No other vessel on this register is recorded with the same builder. The returns for 2020–2025 all give Piraeus as port of registry.
Its 3,911 t of CO₂ for 2025 is 82% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 182.5 kg CO₂, 44% below the type median of 327.0 kg. It logged 1,695 hours at sea against a median of 4,872 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 6 years with reported emissions, the highest was 2021 (15,407 t) and the lowest 2025 (3,911 t). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 4.4% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 36.3% and CO₂ per nautical mile fell 18.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
