KRONPRINS FREDERIK against its type
Built in 1981, it is 19 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 16,071 gross tonnage it is smaller than 61% of the other 470 ro-pax ships with a recorded tonnage. It is one of 7 ro-pax ships here under the Germany flag, 1.4% of the 493 on the register. The same builder is recorded for 3 other vessels here, all of them ro-pax ships. DSB is linked to 2 vessels on this register. The returns for 2018–2025 all give Rostock as port of registry.
Its 5,791 t of CO₂ for 2025 is 81% 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 397.9 kg CO₂, 15% below the type median of 467.6 kg. It logged 1,373 hours at sea against a median of 4,243 hours for its type that year. 0.0% 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 2022 (6,667 t) and the lowest 2020 (1,532 t). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 2.5% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 26.9% and CO₂ per nautical mile fell 22.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
