BOW PROSPER against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 22,500 gross tonnage it is smaller than 52% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 95 chemical tankers here under the Norway flag, 4.1% of the 2,344 on the register. The returns for 2020–2025 all give Bergen as port of registry.
Its 3,821 t of CO₂ for 2025 is 31% 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 293.6 kg CO₂, 17% above the type median of 250.2 kg. It logged 1,081 hours at sea against a median of 2,109 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2021 (6,007 t) and the lowest 2023 (1,651 t). Its efficiency percentile within the type went from 16 in 2020 to 75 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,008 of 1,348 qualifying chemical tankers by EEOI, at the 75th percentile. The dashed line is the type median, 14.4; this vessel reported 23.0.
EEOI divides emissions by transport work, which for this vessel and year was 166,112,609 tonne-miles over 13,011 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 36.3% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 131.4% while distance sailed rose 115.0%and CO₂ per nautical mile rose 7.6%.That points mainly to how much the vessel sailed, rather than the other.
