ARDMORE GIBRALTAR against its type
It is one of 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. Its MRV returns name it ST. PAULI for 2022–2023 and ARDMORE GIBRALTAR for 2024–2025. The returns for 2022–2025 all give SINGAPORE as port of registry.
Its 4,384 t of CO₂ for 2025 is 21% 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 255.3 kg CO₂, close to the type median of 250.2 kg. It logged 1,480 hours at sea against a median of 2,106 hours for its type that year. 10.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2023 (12,915 t) and the lowest 2025 (4,384 t). Its efficiency percentile within the type went from 59 in 2022 to 34 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 455 of 1,348 qualifying chemical tankers by EEOI, at the 34th percentile. The dashed line is the type median, 14.4; this vessel reported 11.7.
EEOI divides emissions by transport work, which for this vessel and year was 375,645,244 tonne-miles over 17,169 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 41.4% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 50.8% while distance sailed fell 52.3%and CO₂ per nautical mile rose 3.2%.That points mainly to how much the vessel sailed, rather than the other.
