JO ROWAN against its type
Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 43,053 gross tonnage it is larger than 99% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. Its MRV returns name it JO ROWAN for 2018–2020 and TORM INTEGRITY for 2023–2025. The returns for 2023–2025 all give Vejle as port of registry.
Its 2,192 t of CO₂ for 2025 is 60% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 306.6 kg CO₂, 23% above the type median of 250.2 kg. It logged 658 hours at sea against a median of 2,106 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2020 (10,923 t) and the lowest 2025 (2,192 t). Its efficiency percentile within the type went from 19 in 2018 to 0 in 2025 (lower is more efficient). Of the 4 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 4 of 1,348 qualifying chemical tankers by EEOI, at the 0th percentile. The dashed line is the type median, 14.4; this vessel reported 5.0.
EEOI divides emissions by transport work, which for this vessel and year was 438,378,000 tonne-miles over 7,150 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 17.6% while distance sailed fell 8.4%and CO₂ per nautical mile fell 10.0%.
