HAFNIA KIRSTEN against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,658 gross tonnage it is larger than 79% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. Thome Ship Management is linked to 42 vessels on this register. The reported port of registry changed: Valletta (2018), then VALLETA (2020–2022), then Valletta (2024–2025).
Its 1,455 t of CO₂ for 2025 is 74% 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 258.3 kg CO₂, close to the type median of 250.2 kg. It logged 465 hours at sea against a median of 2,106 hours for its type that year. 5.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2018 (5,644 t) and the lowest 2022 (821 t). Its efficiency percentile within the type went from 33 in 2018 to 9 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 125 of 1,348 qualifying chemical tankers by EEOI, at the 9th percentile. The dashed line is the type median, 14.4; this vessel reported 7.9.
Across the 39 ranked vessels operated by Thome Ship Management, the median percentile is 54. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 185,077,608 tonne-miles over 5,632 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 74.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 60.2% while distance sailed fell 55.5%and CO₂ per nautical mile fell 10.6%.That points mainly to how much the vessel sailed, rather than the other.
