AVENCA: CO₂ emissions 2018–2025

AVENCA against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,010 gross tonnage it is larger than 90% 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 reported port of registry changed: Limassol (2018), then Liberia (2022–2023), then MONROVIA (2024–2025).

Its 1,738 t of CO₂ for 2025 is 69% 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 268.2 kg CO₂, close to the type median of 250.2 kg. It logged 548 hours at sea against a median of 2,109 hours for its type that year. 8.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2024 (8,734 t) and the lowest 2025 (1,738 t). Its efficiency percentile within the type went from 68 in 2018 to 48 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 645 of 1,348 qualifying chemical tankers by EEOI, at the 48th percentile. The dashed line is the type median, 14.4; this vessel reported 14.0.

EEOI divides emissions by transport work, which for this vessel and year was 123,883,820 tonne-miles over 6,480 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 16.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions fell 80.1% while distance sailed fell 76.7%and CO₂ per nautical mile fell 14.7%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

• Emissions: EU MRV publication (THETIS-MRV), reporting years 2018–2025, published by the European Commission.
• Vessel particulars: Wikidata (CC0).

This page draws on 5 MRV reporting years, an efficiency ranking and 4 of 5 vessel particulars. Not found in the sources for this vessel: AIS movements in Norwegian waters, a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
