CAROLINE RUSS 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 10,488 gross tonnage it is smaller than 80% 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 180 other vessels here, 13 of them ro-ro ships. The reported port of registry changed: Madeira (Portugal) (2018), then Madeira (2019–2022), then Madeira (Portugal) (2023), then Madeira (2024–2025).

Its 28,818 t of CO₂ for 2025 is 35% 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 296.5 kg CO₂, close to the type median of 327.0 kg. It logged 5,355 hours at sea against a median of 4,872 hours for its type that year. 3.9% 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 2018 (38,879 t) and the lowest 2020 (6,037 t). Its efficiency percentile within the type went from 95 in 2021 to 91 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 174 of 192 qualifying ro-ro ships by EEOI, at the 91st percentile. The dashed line is the type median, 85.3; this vessel reported 208.8.

EEOI divides emissions by transport work, which for this vessel and year was 138,025,432 tonne-miles over 97,198 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 25.9% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 13.8% while distance sailed rose 1.5%and CO₂ per nautical mile fell 15.0%.That points mainly to how efficiently it sailed, rather than the other.
