AUTOSKY against its type

Built in 2000, it is 2 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 21,010 gross tonnage it is smaller than 52% of the other 269 ro-ro ships with a recorded tonnage. It is one of 16 ro-ro ships here under the Portugal flag, 5.1% 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 2018–2025 all give Madeira as port of registry.

Its 23,527 t of CO₂ for 2025 is 10% above the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 334.4 kg CO₂, close to the type median of 327.0 kg. It logged 5,549 hours at sea against a median of 4,872 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2022 (32,889 t) and the lowest 2021 (8,271 t). Its efficiency percentile within the type went from 93 in 2018 to 87 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.
