BREMEN against its type
Built in 1990, it is 20 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 6,752 gross tonnage it is smaller than 97% 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 25 other vessels here, 2 of them cruise ships. Hapag-Lloyd Cruises is linked to 6 vessels on this register. Its MRV returns name it BREMEN for 2018–2019 and SEAVENTURE for 2021–2025. The reported port of registry changed: Nassau (2018–2019), then Limassol (2021–2024), then Nassau (2025).
Its 4,392 t of CO₂ for 2025 is 86% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 178.8 kg CO₂, 78% below the type median of 821.3 kg. It logged 2,029 hours at sea against a median of 3,133 hours for its type that year. 0.7% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 7 years with reported emissions, the highest was 2021 (5,205 t) and the lowest 2018 (3,711 t). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 18.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 1.5% and CO₂ per nautical mile fell 16.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
