MARKO POLO against its type
Built in 1973, it is 27 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 10,325 gross tonnage it is smaller than 77% of the other 470 ro-pax ships with a recorded tonnage. It is one of 7 ro-pax ships here under the Croatia flag, 1.4% of the 493 on the register. The same builder is recorded for 9 other vessels here, 2 of them ro-pax ships. Jadrolinija is linked to 3 vessels on this register. The returns for 2018–2025 all give Rijeka as port of registry.
Its 12,039 t of CO₂ for 2025 is 60% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 349.4 kg CO₂, 25% below the type median of 467.6 kg. It logged 2,773 hours at sea against a median of 4,243 hours for its type that year. 19.3% 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 2023 (14,084 t) and the lowest 2020 (8,625 t). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 2.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 1.6% and CO₂ per nautical mile rose 11.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
