PS ROMA against its type
Built in 2011, it is 1 year newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,717 gross tonnage it is larger than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 43 chemical tankers here under the Italy flag, 1.8% of the 2,344 on the register. The reported port of registry changed: Valletta (2020), then Palermo (2021–2025).
Its 2,552 t of CO₂ for 2024 is 56% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 263.6 kg CO₂, close to the type median of 253.5 kg. It logged 938 hours at sea against a median of 2,177 hours for its type that year. 4.8% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2020 (7,985 t) and the lowest 2023 (2,514 t). Its efficiency percentile within the type went from 53 in 2020 to 3 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 39 of 1,194 qualifying chemical tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 15.9; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 364,028,531 tonne-miles over 9,679 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 68.0% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions rose 1.5% while distance sailed rose 5.3%and CO₂ per nautical mile fell 3.6%.
