ARDMORE CHEYENNE against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). 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 52 other vessels here, 48 of them chemical tankers. The returns for 2018–2024 all give Majuro as port of registry.
Its 3,096 t of CO₂ for 2024 is 47% 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 224.8 kg CO₂, 11% below the type median of 253.5 kg. It logged 1,406 hours at sea against a median of 2,177 hours for its type that year. 4.2% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 7 years with reported emissions, the highest was 2018 (8,567 t) and the lowest 2020 (1,141 t). Its efficiency percentile within the type went from 43 in 2018 to 33 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 393 of 1,194 qualifying chemical tankers by EEOI, at the 33rd percentile. The dashed line is the type median, 15.9; this vessel reported 12.0.
EEOI divides emissions by transport work, which for this vessel and year was 258,616,541 tonne-miles over 13,768 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 63.9% lower than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 38.8% while distance sailed fell 33.7%and CO₂ per nautical mile fell 7.7%.That points mainly to how much the vessel sailed, rather than the other.
