ARDMORE ENCOUNTER against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,993 gross tonnage it is larger than 88% 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. The same builder is recorded for 96 other vessels here, 31 of them chemical tankers. The returns for 2018–2025 all give Majuro as port of registry.
Its 1,880 t of CO₂ for 2025 is 66% 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 284.9 kg CO₂, 14% above the type median of 250.2 kg. It logged 534 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%. Across 6 years with reported emissions, the highest was 2024 (6,392 t) and the lowest 2023 (1,564 t). Its efficiency percentile within the type went from 63 in 2018 to 20 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 277 of 1,348 qualifying chemical tankers by EEOI, at the 20th percentile. The dashed line is the type median, 14.4; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 203,683,640 tonne-miles over 6,600 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions fell 70.6% while distance sailed fell 66.7%and CO₂ per nautical mile fell 11.7%.That points mainly to how much the vessel sailed, rather than the other.
