HAMLET against its type
Built in 1997, it is 3 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 10,067 gross tonnage it is smaller than 77% of the other 470 ro-pax ships with a recorded tonnage. It is one of 29 ro-pax ships here under the Denmark flag, 5.9% of the 493 on the register. The returns for 2018–2025 all give Helsingör as port of registry.
Its 4,747 t of CO₂ for 2025 is 84% 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 267.5 kg CO₂, 43% below the type median of 467.6 kg. It logged 2,128 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 2018 (9,035 t) and the lowest 2024 (3,414 t). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 47.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 39.0% and CO₂ per nautical mile rose 48.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
