AVALON 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 16,683 gross tonnage it is smaller than 59% 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. The same builder is recorded for 40 other vessels here, 29 of them chemical tankers. Its MRV returns name it AVALON for 2018–2021 and OLYMPIC SPIRIT for 2022–2025. The reported port of registry changed: Gibraltar (2018–2019), then Bremen (2020–2021), then MONROVIA (2022–2025).
Its 5,143 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 286.6 kg CO₂, 15% above the type median of 250.2 kg. It logged 1,542 hours at sea against a median of 2,106 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (13,964 t) and the lowest 2024 (1,304 t). Its efficiency percentile within the type went from 92 in 2018 to 47 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 634 of 1,348 qualifying chemical tankers by EEOI, at the 47th percentile. The dashed line is the type median, 14.4; this vessel reported 13.9.
EEOI divides emissions by transport work, which for this vessel and year was 370,034,532 tonne-miles over 17,947 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 60.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 294.5% while distance sailed rose 260.1%and CO₂ per nautical mile rose 9.6%.That points mainly to how much the vessel sailed, rather than the other.
