LIBRA II against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 24,576 gross tonnage it is larger than 57% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 44 other vessels here, one of them a chemical tanker. Its MRV returns name it LIBRA II for 2021 and SARIYAH for 2025.
Its 3,691 t of CO₂ for 2025 is 33% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 425.9 kg CO₂, 1.7 times the type median of 250.2 kg. It logged 948 hours at sea against a median of 2,106 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 93 in 2021 to 89 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,204 of 1,348 qualifying chemical tankers by EEOI, at the 89th percentile. The dashed line is the type median, 14.4; this vessel reported 36.3.
EEOI divides emissions by transport work, which for this vessel and year was 101,660,424 tonne-miles over 8,667 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 46.2% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2021 to 2025, emissions fell 46.2% while distance sailed fell 57.7%and CO₂ per nautical mile rose 27.3%.That points mainly to how much the vessel sailed, rather than the other.
