IVER AMBITION against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 6,296 gross tonnage it is smaller than 93% 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 same builder is recorded for 5 other vessels here. The reported port of registry changed: Genoa (2018–2022), then Madeira (2023–2025).
Its 8,867 t of CO₂ for 2025 is 1.6 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 171.4 kg CO₂, 31% below the type median of 250.2 kg. It logged 5,328 hours at sea against a median of 2,109 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (11,007 t) and the lowest 2020 (1,609 t). Its efficiency percentile within the type went from 96 in 2019 to 92 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 1,245 of 1,348 qualifying chemical tankers by EEOI, at the 92nd percentile. The dashed line is the type median, 14.4; this vessel reported 39.0.
EEOI divides emissions by transport work, which for this vessel and year was 227,119,365 tonne-miles over 51,725 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 223.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 17.9% while distance sailed rose 16.6%and CO₂ per nautical mile rose 1.1%.That points mainly to how much the vessel sailed, rather than the other.
