SERENITY ACE against its type
Built in 2008, it is the same age as the median vehicle carrier on this register (build year 2008, 595 vessels with a known build year). At 57,692 gross tonnage it is smaller than 58% of the other 571 vehicle carriers with a recorded tonnage. It is one of 73 vehicle carriers here under the Bahamas flag, 10.2% of the 713 on the register. The same builder is recorded for 75 other vessels here, 31 of them vehicle carriers. Its MRV returns name it SERENITY ACE for 2018–2022 and SERENITY HIGHWAY for 2023–2025. The returns for 2018–2025 all give Nassau as port of registry.
Its 177 t of CO₂ for 2025 is 97% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 566.0 kg CO₂, 1.8 times the type median of 309.1 kg. It logged 60 hours at sea against a median of 1,639 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2020 (11,700 t) and the lowest 2025 (177 t). Its efficiency percentile within the type went from 66 in 2018 to 76 in 2024 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 98.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 93.4% and CO₂ per nautical mile rose 81.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
