ATLANTIC LEO 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 29,266 gross tonnage it is larger than 69% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it ATLANTIC LEO for 2018 and VELOS LEO for 2019–2024. The reported port of registry changed: Hong Kong (2018–2019), then Majuro (2020–2024).
Its 2,619 t of CO₂ for 2024 is 55% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 274.4 kg CO₂, close to the type median of 253.5 kg. It logged 910 hours at sea against a median of 2,177 hours for its type that year. 2.6% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2022 (15,207 t) and the lowest 2018 (1,618 t). Its efficiency percentile within the type went from 4 in 2018 to 46 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 547 of 1,194 qualifying chemical tankers by EEOI, at the 46th percentile. The dashed line is the type median, 15.9; this vessel reported 14.7.
EEOI divides emissions by transport work, which for this vessel and year was 177,930,706 tonne-miles over 9,544 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 61.9% higher than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 42.3% while distance sailed fell 43.1%and CO₂ per nautical mile rose 1.4%.That points mainly to how much the vessel sailed, rather than the other.
