SLOMAN HEBE against its type
It is one of 7 chemical tankers here under the Antigua and Barbuda flag, 0.3% of the 2,344 on the register. The reported port of registry changed: ST. JOHN'S (2023–2024), then St Johns (2025).
Its 5,902 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 204.1 kg CO₂, 18% below the type median of 250.2 kg. It logged 2,853 hours at sea against a median of 2,106 hours for its type that year. 21.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2024 (7,065 t) and the lowest 2023 (4,648 t). Its efficiency percentile within the type was 80 in both 2023 and 2025. Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,077 of 1,348 qualifying chemical tankers by EEOI, at the 80th percentile. The dashed line is the type median, 14.4; this vessel reported 26.3.
EEOI divides emissions by transport work, which for this vessel and year was 224,085,421 tonne-miles over 28,926 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 27.0% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 16.5% while distance sailed fell 23.3%and CO₂ per nautical mile rose 8.9%.That points mainly to how much the vessel sailed, rather than the other.
