STOLT EBONY 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 23,124 gross tonnage it is smaller than 51% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The returns for 2021–2025 all give Madeira as port of registry.
Its 1,569 t of CO₂ for 2025 is 72% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 199.1 kg CO₂, 20% below the type median of 250.2 kg. It logged 685 hours at sea against a median of 2,109 hours for its type that year. 6.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2024 (11,684 t) and the lowest 2025 (1,569 t). Its efficiency percentile within the type went from 31 in 2018 to 35 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 467 of 1,348 qualifying chemical tankers by EEOI, at the 35th percentile. The dashed line is the type median, 14.4; this vessel reported 11.9.
EEOI divides emissions by transport work, which for this vessel and year was 132,291,737 tonne-miles over 7,882 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 75.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 86.6% while distance sailed fell 83.5%and CO₂ per nautical mile fell 18.6%.That points mainly to how much the vessel sailed, rather than the other.
