DEE4 MAHOGANY against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2022–2024 all give MONROVIA as port of registry.
Its 1,846 t of CO₂ for 2024 is 68% 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 241.9 kg CO₂, close to the type median of 253.5 kg. It logged 691 hours at sea against a median of 2,177 hours for its type that year. 7.5% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 3 years with reported emissions, the highest was 2023 (6,161 t) and the lowest 2024 (1,846 t). Its efficiency percentile within the type went from 2 in 2022 to 3 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 42 of 1,194 qualifying chemical tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 15.9; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 262,529,161 tonne-miles over 7,630 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 69.3% lower than in 2022, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 70.0% while distance sailed fell 71.9%and CO₂ per nautical mile rose 6.5%.That points mainly to how much the vessel sailed, rather than the other.
