AVON against its type
Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,528 gross tonnage it is larger than 76% 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 AVON for 2019–2022 and ISABELLA M II for 2024–2025. The returns for 2019–2025 all give Monrovia as port of registry.
Its 2,820 t of CO₂ for 2024 is 52% 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 213.8 kg CO₂, 16% below the type median of 253.5 kg. It logged 1,139 hours at sea against a median of 2,177 hours for its type that year. 2.2% 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 (2,922 t) and the lowest 2019 (1,804 t). Its efficiency percentile within the type went from 35 in 2019 to 55 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 665 of 1,194 qualifying chemical tankers by EEOI, at the 55th percentile. The dashed line is the type median, 15.9; this vessel reported 17.4.
EEOI divides emissions by transport work, which for this vessel and year was 161,708,142 tonne-miles over 13,190 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 56.4% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.
From 2022 to 2024, emissions rose 38.5% while distance sailed rose 36.6%and CO₂ per nautical mile rose 1.4%.That points mainly to how much the vessel sailed, rather than the other.
