GWEN 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 11,653 gross tonnage it is smaller than 75% 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 GWEN for 2022–2024 and LILA VANCOUVER for 2025. The reported port of registry changed: majuro (2022–2024), then MONROVIA (2025).
Its 823 t of CO₂ for 2024 is 86% 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 233.7 kg CO₂, close to the type median of 253.5 kg. It logged 274 hours at sea against a median of 2,177 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 3 years with reported emissions, the highest was 2022 (2,724 t) and the lowest 2023 (597 t). Its efficiency percentile within the type went from 58 in 2022 to 36 in 2024 (lower is more efficient).
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 431 of 1,194 qualifying chemical tankers by EEOI, at the 36th percentile. The dashed line is the type median, 15.9; this vessel reported 12.7.
EEOI divides emissions by transport work, which for this vessel and year was 64,831,363 tonne-miles over 3,520 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 69.8% lower than in 2022, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 37.9% and CO₂ per nautical mile fell 1.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
