HAFNIA LIBRA against its type
Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,312 gross tonnage it is larger than 95% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The returns for 2021–2025 all give KØBENHAVN as port of registry.
Its 4,830 t of CO₂ for 2025 is 13% 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 354.2 kg CO₂, 42% above the type median of 250.2 kg. It logged 1,336 hours at sea against a median of 2,106 hours for its type that year. 11.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2024 (8,234 t) and the lowest 2021 (2,591 t). Its efficiency percentile within the type went from 76 in 2018 to 32 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 434 of 1,348 qualifying chemical tankers by EEOI, at the 32nd percentile. The dashed line is the type median, 14.4; this vessel reported 11.4.
EEOI divides emissions by transport work, which for this vessel and year was 423,711,404 tonne-miles over 13,638 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 15.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 41.3% while distance sailed fell 54.0%and CO₂ per nautical mile rose 27.4%.That points mainly to how much the vessel sailed, rather than the other.
