STENA IMPECCABLE: CO₂ emissions 2018–2025

STENA IMPECCABLE 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 29,680 gross tonnage it is larger than 80% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 7 chemical tankers here under the Bermuda flag, 0.3% of the 2,344 on the register. The same builder is recorded for 192 other vessels here, 87 of them chemical tankers. The reported port of registry changed: Hamilton (2020–2022), then JACKSONVILLE FL (2024–2025).

Its 2,805 t of CO₂ for 2025 is 49% 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 349.6 kg CO₂, 40% above the type median of 250.2 kg. It logged 738 hours at sea against a median of 2,109 hours for its type that year. 11.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2024 (12,452 t) and the lowest 2025 (2,805 t). Its efficiency percentile within the type went from 6 in 2018 to 69 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 931 of 1,348 qualifying chemical tankers by EEOI, at the 69th percentile. The dashed line is the type median, 14.4; this vessel reported 20.4.

EEOI divides emissions by transport work, which for this vessel and year was 137,832,432 tonne-miles over 8,022 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 61.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.

From 2024 to 2025, emissions fell 77.5% while distance sailed fell 82.3%and CO₂ per nautical mile rose 27.4%.That points mainly to how much the vessel sailed, rather than the other.
