UHL FREEDOM against its type
It is one of 52 vessels in the other ship types category here under the Portugal flag, 10.4% of the 499 on the register. The reported port of registry changed: Madeira (2021), then Maderia (2022), then Madeira (2023–2025).
Its 3,120 t of CO₂ for 2025 is 39% below the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 223.0 kg CO₂, close to the type median of 231.1 kg. It logged 1,070 hours at sea against a median of 2,231 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 5 years with reported emissions, the highest was 2022 (9,217 t) and the lowest 2023 (2,923 t). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021
Position 10 of 47 qualifying other ship typess by EEOI, at the 20th percentile. The dashed line is the type median, 157.4; this vessel reported 47.4.
EEOI divides emissions by transport work, which for this vessel and year was 106,277,215 tonne-miles over 25,588 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 38.1% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 63.5% and CO₂ per nautical mile rose 12.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
