MTM KEY WEST against its type
Built in 2020, it is 10 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 205 chemical tankers here under the Singapore flag, 8.7% of the 2,344 on the register. The same builder is recorded for 307 other vessels here, 98 of them chemical tankers. The returns for 2020–2024 all give Singapore as port of registry.
Its 3,318 t of CO₂ for 2024 is 43% 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 216.4 kg CO₂, 15% below the type median of 253.5 kg. It logged 1,468 hours at sea against a median of 2,177 hours for its type that year. 5.2% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2020 (3,801 t) and the lowest 2023 (623 t). Its efficiency percentile within the type went from 36 in 2020 to 21 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 256 of 1,194 qualifying chemical tankers by EEOI, at the 21st percentile. The dashed line is the type median, 15.9; this vessel reported 10.1.
EEOI divides emissions by transport work, which for this vessel and year was 328,852,329 tonne-miles over 15,331 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 12.7% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions rose 432.8% and CO₂ per nautical mile fell 39.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
