TASING SWAN against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 7,232 gross tonnage it is smaller than 91% 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. The returns for 2018–2025 all give Middelfart as port of registry.
Its 7,133 t of CO₂ for 2025 is 29% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 175.1 kg CO₂, 30% below the type median of 250.2 kg. It logged 4,187 hours at sea against a median of 2,109 hours for its type that year. 10.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2019 (9,465 t) and the lowest 2022 (2,103 t). Its efficiency percentile within the type went from 88 in 2018 to 90 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,213 of 1,348 qualifying chemical tankers by EEOI, at the 90th percentile. The dashed line is the type median, 14.4; this vessel reported 37.2.
EEOI divides emissions by transport work, which for this vessel and year was 191,745,699 tonne-miles over 40,746 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 239.3% and CO₂ per nautical mile rose 7.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
