EXCELLO against its type
Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 13,798 gross tonnage it is smaller than 64% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 17 chemical tankers here under the Sweden flag, 0.7% of the 2,344 on the register. The reported port of registry changed: Donso (2018–2022), then Donsö (2023–2025).
Its 9,388 t of CO₂ for 2025 is 1.7 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 278.4 kg CO₂, 11% above the type median of 250.2 kg. It logged 4,009 hours at sea against a median of 2,109 hours for its type that year. 12.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (11,996 t) and the lowest 2023 (6,554 t). Its efficiency percentile within the type went from 83 in 2018 to 87 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,176 of 1,348 qualifying chemical tankers by EEOI, at the 87th percentile. The dashed line is the type median, 14.4; this vessel reported 33.6.
EEOI divides emissions by transport work, which for this vessel and year was 279,641,346 tonne-miles over 33,722 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 21.7% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 14.3% while distance sailed fell 1.9%and CO₂ per nautical mile fell 12.6%.That points mainly to how efficiently it sailed, rather than the other.
