WISTERIA ACE against its type
Built in 2007, it is 1 year older than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 59,952 gross tonnage it is larger than 62% of the other 571 vehicle carriers with a recorded tonnage. It is one of 89 vehicle carriers here under the Liberia flag, 12.5% of the 713 on the register. The same builder is recorded for 102 other vessels here, 50 of them vehicle carriers. The returns for 2018–2025 all give MONROVIA as port of registry.
Its 83 t of CO₂ for 2025 is 99% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 258.7 kg CO₂, 16% below the type median of 309.1 kg. It logged 39 hours at sea against a median of 1,639 hours for its type that year. 7.0% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 7 years with reported emissions, the highest was 2023 (7,567 t) and the lowest 2025 (83 t). Its efficiency percentile within the type went from 17 in 2018 to 87 in 2023 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 97.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 98.6% and CO₂ per nautical mile fell 24.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
