STI MAYFAIR 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 29,735 gross tonnage it is larger than 82% 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 180 other vessels here, 53 of them chemical tankers. The returns for 2021–2022 all give Majuro as port of registry.
Its 3,616 t of CO₂ for 2022 is 38% below the median of 5,807 t among the 1,486 chemical tankers on this register that reported for 2022. Per nautical mile it emitted 292.3 kg CO₂, close to the type median of 266.3 kg. It logged 1,007 hours at sea against a median of 1,995 hours for its type that year. 5.8% of its 2022 emissions were at berth; the median for chemical tankers was 8.6%. Its efficiency percentile within the type went from 27 in 2021 to 10 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2022
Position 137 of 1,334 qualifying chemical tankers by EEOI, at the 10th percentile. The dashed line is the type median, 15.7; this vessel reported 9.0.
EEOI divides emissions by transport work, which for this vessel and year was 401,294,118 tonne-miles over 12,371 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 105.5% higher than in 2021, for EU/EEA voyages only.
From 2021 to 2022, emissions rose 105.5% while distance sailed rose 93.8%and CO₂ per nautical mile rose 6.1%.That points mainly to how much the vessel sailed, rather than the other.
