STENA HORIZON against its type
Built in 2006, it is 6 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 27,552 gross tonnage it is larger than 63% of the other 470 ro-pax ships with a recorded tonnage. It is one of 82 ro-pax ships here under the Cyprus flag, 16.6% of the 493 on the register. The reported port of registry changed: Bari (2018–2023), then Limassol (2024–2025).
Its 46,484 t of CO₂ for 2025 is 1.5 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 456.3 kg CO₂, close to the type median of 467.6 kg. It logged 5,625 hours at sea against a median of 4,243 hours for its type that year. 4.1% 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 2018 (48,326 t) and the lowest 2024 (39,478 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 3.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 17.7% and CO₂ per nautical mile fell 1.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
