SLOMAN HESTIA 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 11,316 gross tonnage it is smaller than 79% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 7 chemical tankers here under the Antigua and Barbuda flag, 0.3% of the 2,344 on the register. Its MRV returns name it SLOMAN HESTIA for 2020–2021, SLOMAN HESTIA (SLOMAN HESTIA) for 2022 and SLOMAN HESTIA for 2023–2025. The reported port of registry changed: Saint John's (2020–2021), then Saint John's (AG SJO) (2022), then ST. JOHN'S (2023–2024), then Saint John's (2025).
Its 6,056 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 199.6 kg CO₂, 20% below the type median of 250.2 kg. It logged 3,022 hours at sea against a median of 2,109 hours for its type that year. 16.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (6,993 t) and the lowest 2020 (1,238 t). Its efficiency percentile within the type went from 14 in 2020 to 83 in 2025 (lower is more efficient). 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 1,117 of 1,348 qualifying chemical tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 14.4; this vessel reported 28.7.
EEOI divides emissions by transport work, which for this vessel and year was 210,710,856 tonne-miles over 30,341 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 389.1% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 17.0% while distance sailed rose 15.1%and CO₂ per nautical mile rose 1.7%.That points mainly to how much the vessel sailed, rather than the other.
