SYMPHONY OF THE SEAS against its type
Built in 2018, it is 12 years newer than the median passenger ship on this register, which was built in 2006 (127 vessels with a known build year). At 228,081 gross tonnage it is larger than 99% of the other 117 passenger ships with a recorded tonnage. It is one of 40 passenger ships here under the Bahamas flag, 30.3% of the 132 on the register. The same builder is recorded for 51 other vessels here, 8 of them passenger ships. Royal Caribbean International is linked to 25 vessels on this register. The returns for 2018–2023 all give Nassau as port of registry.
Its 89,064 t of CO₂ for 2023 is 8.2 times the median of 10,915 t among the 54 passenger ships on this register that reported for 2023. Per nautical mile it emitted 1,598.1 kg CO₂, 2.7 times the type median of 595.9 kg. It logged 3,410 hours at sea against a median of 2,376 hours for its type that year. 18.4% of its 2023 emissions were at berth; the median for passenger ships was 15.6%. The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2023 was 4.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2018 to 2023, emissions rose 4.5% and CO₂ per nautical mile rose 0.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
