STENA IMPERATIVE against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,680 gross tonnage it is larger than 80% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 3 chemical tankers here under the United States flag, 0.1% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The returns for 2020–2022 all give Hamilton as port of registry.
Its 3,095 t of CO₂ for 2022 is 47% below the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 331.5 kg CO₂, 24% above the type median of 266.3 kg. It logged 955 hours at sea against a median of 1,995 hours for its type that year. 10.0% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Across 4 years with reported emissions, the highest was 2018 (6,122 t) and the lowest 2020 (1,705 t). Its efficiency percentile within the type went from 26 in 2018 to 8 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 107 of 1,334 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 15.7; this vessel reported 8.5.
EEOI divides emissions by transport work, which for this vessel and year was 363,279,343 tonne-miles over 9,337 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 49.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2020 to 2022, emissions rose 81.6% while distance sailed rose 35.6%and CO₂ per nautical mile rose 33.9%.
