ARDMORE EXPLORER 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 2019–2025 all give Majuro as port of registry.
Its 4,545 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 322.4 kg CO₂, 29% above the type median of 250.2 kg. It logged 1,297 hours at sea against a median of 2,106 hours for its type that year. 15.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2020 (8,244 t) and the lowest 2022 (1,381 t). Its efficiency percentile within the type went from 9 in 2019 to 29 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 389 of 1,348 qualifying chemical tankers by EEOI, at the 29th percentile. The dashed line is the type median, 14.4; this vessel reported 10.8.
EEOI divides emissions by transport work, which for this vessel and year was 421,221,501 tonne-miles over 14,098 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 93.8% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 157.4% while distance sailed rose 168.2%and CO₂ per nautical mile fell 4.0%.That points mainly to how much the vessel sailed, rather than the other.
