TREASURE against its type

Built in 1999, it is 3 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 58,684 gross tonnage it is larger than 94% of the other 269 ro-ro ships with a recorded tonnage. It is one of 9 ro-ro ships here under the Liberia flag, 2.9% of the 311 on the register. The same builder is recorded for 360 other vessels here, 4 of them ro-ro ships. The returns for 2021–2025 all give Monrovia as port of registry.

Its 6,401 t of CO₂ for 2025 is 70% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 299.9 kg CO₂, close to the type median of 327.0 kg. It logged 1,463 hours at sea against a median of 4,872 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 5 years with reported emissions, the highest was 2022 (10,606 t) and the lowest 2023 (2,311 t). Its efficiency percentile within the type went from 20 in 2018 to 15 in 2022 (lower is more efficient). Of the 3 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 65.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2024, so the series has gaps.

From 2023 to 2025, emissions rose 177.0% and CO₂ per nautical mile fell 11.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
