LASCAUX 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 6,953 gross tonnage it is smaller than 92% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The same builder is recorded for 13 other vessels here, 4 of them chemical tankers. The reported port of registry changed: Luxembourg (2018–2020), then VALLETTA (2022–2025).
Its 4,581 t of CO₂ for 2025 is 17% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 189.6 kg CO₂, 24% below the type median of 250.2 kg. It logged 3,070 hours at sea against a median of 2,109 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2024 (8,042 t) and the lowest 2022 (3,383 t). Its efficiency percentile within the type went from 99 in 2018 to 95 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,281 of 1,348 qualifying chemical tankers by EEOI, at the 95th percentile. The dashed line is the type median, 14.4; this vessel reported 43.8.
EEOI divides emissions by transport work, which for this vessel and year was 104,716,114 tonne-miles over 24,161 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 33.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 43.0% while distance sailed fell 35.6%and CO₂ per nautical mile fell 11.6%.That points mainly to how much the vessel sailed, rather than the other.
