GULF PETROLEUM 4 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 2024–2025 all give Monrovia as port of registry.
Its 4,521 t of CO₂ for 2025 is 18% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 143.9 kg CO₂, 42% below the type median of 250.2 kg. It logged 3,856 hours at sea against a median of 2,106 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 66 in 2024 to 73 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 984 of 1,348 qualifying chemical tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 14.4; this vessel reported 22.0.
EEOI divides emissions by transport work, which for this vessel and year was 205,782,431 tonne-miles over 31,414 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 206.9% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 206.9% while distance sailed rose 235.6%and CO₂ per nautical mile fell 8.6%.That points mainly to how much the vessel sailed, rather than the other.
