SAPPHIRE PRINCESS against its type
Built in 2004, it is 2 years older than the median passenger ship on this register, which was built in 2006 (127 vessels with a known build year). At 115,875 gross tonnage it is larger than 81% of the other 117 passenger ships with a recorded tonnage. It is one of 2 passenger ships here under the United Kingdom flag, 1.5% of the 132 on the register. The same builder is recorded for 25 other vessels here. Carnival Cruise Line is linked to 18 vessels on this register. The returns for 2018–2019 all give London as port of registry.
Its 95,288 t of CO₂ for 2019 is 4.2 times the median of 22,875 t among the 69 passenger ships on this register that reported for 2019. Per nautical mile it emitted 1,477.0 kg CO₂, 1.8 times the type median of 805.0 kg. It logged 4,095 hours at sea against a median of 3,334 hours for its type that year. 7.3% of its 2019 emissions were at berth; the median for passenger ships was 11.4%. Of the 2 comparable vessels listed below with a 2019 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2019 was 15.7% higher than in 2018, for EU/EEA voyages only.
From 2018 to 2019, emissions rose 15.7% and CO₂ per nautical mile rose 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
