AKKA against its type
Built in 2001, it is 1 year newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 36,468 gross tonnage it is larger than 84% 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 29 other vessels here, 15 of them ro-pax ships. TT-Line is linked to 6 vessels on this register. Its MRV returns name it NILS HOLGERSSON for 2018–2020 and AKKA for 2021–2025. The reported port of registry changed: Luebeck (2018–2023), then Lubeck (2024–2025).
Its 80,244 t of CO₂ for 2025 is 2.7 times the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 676.2 kg CO₂, 45% above the type median of 467.6 kg. It logged 6,462 hours at sea against a median of 4,243 hours for its type that year. 4.6% 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 2025 (80,244 t) and the lowest 2024 (40,534 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 57.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 98.0% and CO₂ per nautical mile rose 22.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
