STENA IMPULSE 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 29,666 gross tonnage it is larger than 79% 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. Its MRV returns name it STENAWECO IMPULSE for 2018–2020 and STENA IMPULSE for 2021–2023. The reported port of registry changed: Hamilton (2020–2022), then Hellerup (2023).
Its 3,853 t of CO₂ for 2023 is 29% below the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 310.3 kg CO₂, 20% above the type median of 258.0 kg. It logged 1,045 hours at sea against a median of 1,919 hours for its type that year. 10.1% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 6 years with reported emissions, the highest was 2020 (11,631 t) and the lowest 2021 (1,463 t). Its efficiency percentile within the type went from 5 in 2018 to 8 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 98 of 1,230 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 15.6; this vessel reported 8.6.
EEOI divides emissions by transport work, which for this vessel and year was 446,507,532 tonne-miles over 12,417 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 48.4% lower than in 2018, for EU/EEA voyages only.
From 2022 to 2023, emissions fell 20.0% while distance sailed fell 4.9%and CO₂ per nautical mile fell 15.9%.That points mainly to how efficiently it sailed, rather than the other.
