GASCHEM AACHEN against its type
Built in 2003, it is 10 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 25,299 gross tonnage it is larger than 55% of the other 525 gas carriers with a recorded tonnage. It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. The same builder is recorded for 5 other vessels here. Its MRV returns name it MAROLA for 2019–2020, GASCHEM AACHEN for 2021–2022 and PRIESTLEY for 2023. The reported port of registry changed: Genova (2019–2020), then Monrovia (2021–2023).
Its 3,094 t of CO₂ for 2023 is 46% below the median of 5,702 t among the 338 gas carriers on this register that reported for 2023. Per nautical mile it emitted 451.3 kg CO₂, 1.7 times the type median of 262.3 kg. It logged 580 hours at sea against a median of 1,868 hours for its type that year. 25.4% of its 2023 emissions were at berth; the median for gas carriers was 4.5%. Across 5 years with reported emissions, the highest was 2021 (18,962 t) and the lowest 2020 (2,848 t). Its efficiency percentile within the type went from 32 in 2019 to 36 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 107 of 297 qualifying gas carriers by EEOI, at the 36th percentile. The dashed line is the type median, 38.5; this vessel reported 27.6.
EEOI divides emissions by transport work, which for this vessel and year was 112,295,826 tonne-miles over 6,856 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 24.1% lower than in 2019, for EU/EEA voyages only.
From 2022 to 2023, emissions fell 43.5% while distance sailed fell 57.9%and CO₂ per nautical mile rose 34.1%.That points mainly to how much the vessel sailed, rather than the other.
