K INSET 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 8,450 gross tonnage it is smaller than 86% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. Its MRV returns name it SAWTOOTH for 2019–2021 and K INSET for 2022–2025. The reported port of registry changed: Majuro (2019–2021), then Monrovia (2022–2025).
Its 4,379 t of CO₂ for 2024 is 25% 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 187.9 kg CO₂, 26% below the type median of 253.5 kg. It logged 2,156 hours at sea against a median of 2,177 hours for its type that year. 15.3% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 5 years with reported emissions, the highest was 2023 (7,617 t) and the lowest 2021 (1,618 t). Its efficiency percentile within the type went from 98 in 2019 to 89 in 2024 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 1,058 of 1,194 qualifying chemical tankers by EEOI, at the 89th percentile. The dashed line is the type median, 15.9; this vessel reported 37.7.
EEOI divides emissions by transport work, which for this vessel and year was 116,070,766 tonne-miles over 23,307 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 38.6% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2023 to 2024, emissions fell 42.5% while distance sailed fell 34.2%and CO₂ per nautical mile fell 12.7%.That points mainly to how much the vessel sailed, rather than the other.
