ROSSANA against its type
Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 25,546 gross tonnage it is smaller than 75% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 157 bulk carriers here under the Portugal flag, 1.9% of the 8,138 on the register. The same builder is recorded for 118 other vessels here, 105 of them bulk carriers. The reported port of registry changed: Monrovia (2018–2024), then Madeira (2025).
Its 3,365 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 219.3 kg CO₂, 16% below the type median of 260.7 kg. It logged 1,489 hours at sea against a median of 1,200 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2020 (11,851 t) and the lowest 2019 (1,536 t). Its efficiency percentile within the type went from 72 in 2018 to 59 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,927 of 3,241 qualifying bulk carriers by EEOI, at the 59th percentile. The dashed line is the type median, 7.6; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 405,908,323 tonne-miles over 15,343 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 42.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 32.9% while distance sailed rose 6.9%and CO₂ per nautical mile rose 24.3%.That points mainly to how efficiently it sailed, rather than the other.
