GASCHEM HAMBURG against its type
Built in 2010, it is 3 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 22,977 gross tonnage it is smaller than 51% of the other 525 gas carriers with a recorded tonnage. It is one of 99 gas carriers here under the Panama flag, 14.4% of the 688 on the register. The same builder is recorded for 983 other vessels here, 64 of them gas carriers. Its MRV returns name it GASCHEM HAMBURG for 2018–2019 and GREEN PIONEER for 2022–2023. The reported port of registry changed: Monrovia (2018–2019), then PANAMA (2022–2023).
Its 6,427 t of CO₂ for 2023 is 13% above the median of 5,702 t among the 338 gas carriers on this register that reported for 2023. Per nautical mile it emitted 287.5 kg CO₂, close to the type median of 262.3 kg. It logged 1,550 hours at sea against a median of 1,868 hours for its type that year. 0.6% of its 2023 emissions were at berth; the median for gas carriers was 4.5%. Across 4 years with reported emissions, the highest was 2023 (6,427 t) and the lowest 2018 (1,079 t). Its efficiency percentile within the type went from 9 in 2018 to 72 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 213 of 297 qualifying gas carriers by EEOI, at the 72nd percentile. The dashed line is the type median, 38.5; this vessel reported 66.8.
EEOI divides emissions by transport work, which for this vessel and year was 96,280,300 tonne-miles over 22,352 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 495.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2022 to 2023, emissions rose 79.3% while distance sailed rose 129.8%and CO₂ per nautical mile fell 22.0%.That points mainly to how much the vessel sailed, rather than the other.
