EXPLORER OF THE SEAS against its type
Built in 2000, it is 10 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 138,194 gross tonnage it is larger than 83% of the other 177 cruise ships with a recorded tonnage. It is one of 67 cruise ships here under the Bahamas flag, 33.2% of the 202 on the register. The same builder is recorded for 19 other vessels here, 6 of them cruise ships. Royal Caribbean International is linked to 25 vessels on this register. The returns for 2019–2025 all give Nassau as port of registry.
Its 58,785 t of CO₂ for 2025 is 1.9 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,269.4 kg CO₂, 1.5 times the type median of 821.3 kg. It logged 2,708 hours at sea against a median of 3,133 hours for its type that year. 14.3% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 5 years with reported emissions, the highest was 2019 (83,921 t) and the lowest 2020 (5,675 t). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 30.0% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 14.0% and CO₂ per nautical mile rose 5.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
