FAIRCHEM COLT against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,626 gross tonnage it is smaller than 76% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 15 chemical tankers here under the South Korea flag, 0.6% of the 2,344 on the register. The same builder is recorded for 17 other vessels here, 14 of them chemical tankers. Its MRV returns name it FAIRCHEM COLT for 2018–2019, MARMOTAS for 2020–2022 and YC DAISY for 2025. The reported port of registry changed: Majuro (2018–2022), then Jeju (2025).
Its 1,855 t of CO₂ for 2025 is 66% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 189.9 kg CO₂, 24% below the type median of 250.2 kg. It logged 833 hours at sea against a median of 2,109 hours for its type that year. 4.3% 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 (6,955 t) and the lowest 2022 (788 t). Its efficiency percentile within the type went from 57 in 2018 to 73 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 988 of 1,348 qualifying chemical tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 14.4; this vessel reported 22.2.
EEOI divides emissions by transport work, which for this vessel and year was 83,655,390 tonne-miles over 9,767 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 135.3% and CO₂ per nautical mile fell 24.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
