WORLD VOYAGER against its type
Built in 2020, it is 10 years newer than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 7,823 gross tonnage it is smaller than 96% of the other 177 cruise ships with a recorded tonnage. It is one of 5 cruise ships here under the Portugal flag, 2.5% of the 202 on the register. Atlas Ocean Voyages is linked to 2 vessels on this register. The returns for 2020–2025 all give Madeira as port of registry.
Its 6,368 t of CO₂ for 2025 is 80% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 245.8 kg CO₂, 70% below the type median of 821.3 kg. It logged 2,218 hours at sea against a median of 3,133 hours for its type that year. 9.2% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 6 years with reported emissions, the highest was 2022 (9,876 t) and the lowest 2020 (846 t). Of the 8 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 653.1% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 22.6% and CO₂ per nautical mile fell 1.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
