RO QUEEN against its type
Built in 1995, it is 7 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 13,038 gross tonnage it is smaller than 71% of the other 269 ro-ro ships with a recorded tonnage. It is one of 13 ro-ro ships here under the Panama flag, 4.2% of the 311 on the register. Its MRV returns name it SEA AMAZON for 2018–2019, SEA AMAZON H for 2020–2021 and RO QUEEN for 2022–2024. The reported port of registry changed: Valletta (2018–2022), then Panama (2023–2024).
Its 1,039 t of CO₂ for 2024 is 96% below the median of 23,708 t among the 228 ro-ro ships on this register that reported for 2024. Per nautical mile it emitted 253.6 kg CO₂, 22% below the type median of 326.0 kg. It logged 723 hours at sea against a median of 5,156 hours for its type that year. 3.2% of its 2024 emissions were at berth; the median for ro-ro ships was 4.2%. Across 7 years with reported emissions, the highest was 2023 (14,994 t) and the lowest 2024 (1,039 t). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2024 was 90.1% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 93.1% and CO₂ per nautical mile rose 19.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
