ATLANTIC TWIN 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 10,549 gross tonnage it is smaller than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 12 chemical tankers here under the Gibraltar flag, 0.5% of the 2,344 on the register. The same builder is recorded for 9 other vessels here. The returns for 2018–2025 all give Gibraltar as port of registry.
Its 6,614 t of CO₂ for 2025 is 20% 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 227.5 kg CO₂, close to the type median of 250.2 kg. It logged 2,917 hours at sea against a median of 2,109 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (8,334 t) and the lowest 2021 (4,848 t). Its efficiency percentile within the type went from 89 in 2018 to 85 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,140 of 1,348 qualifying chemical tankers by EEOI, at the 85th percentile. The dashed line is the type median, 14.4; this vessel reported 30.3.
EEOI divides emissions by transport work, which for this vessel and year was 218,136,544 tonne-miles over 29,073 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 12.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.2% while distance sailed rose 0.2%and CO₂ per nautical mile fell 3.5%.That points mainly to how efficiently it sailed, rather than the other.
