SILVER WHISPER against its type
Built in 2001, it is 9 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 28,258 gross tonnage it is smaller than 86% 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. Silversea Cruises is linked to 8 vessels on this register. The returns for 2018–2025 all give Nassau as port of registry.
Its 18,467 t of CO₂ for 2025 is 41% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 533.8 kg CO₂, 35% below the type median of 821.3 kg. It logged 2,779 hours at sea against a median of 3,133 hours for its type that year. 18.5% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 6 years with reported emissions, the highest was 2024 (20,306 t) and the lowest 2021 (259 t). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 3.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 9.1% and CO₂ per nautical mile rose 6.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
