THEANOULA against its type
It is one of 3 chemical tankers here under the Luxembourg flag, 0.1% of the 2,344 on the register. The reported port of registry changed: Nassau (2022–2024), then Luxembourg (2025).
Its 7,966 t of CO₂ for 2025 is 44% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 306.3 kg CO₂, 22% above the type median of 250.2 kg. It logged 3,331 hours at sea against a median of 2,106 hours for its type that year. 14.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (12,910 t) and the lowest 2022 (4,187 t). Its efficiency percentile within the type went from 30 in 2022 to 64 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 856 of 1,348 qualifying chemical tankers by EEOI, at the 64th percentile. The dashed line is the type median, 14.4; this vessel reported 18.1.
EEOI divides emissions by transport work, which for this vessel and year was 440,088,950 tonne-miles over 26,002 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 90.2% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 38.3% while distance sailed fell 41.6%and CO₂ per nautical mile rose 5.6%.That points mainly to how much the vessel sailed, rather than the other.
