GAS LISBON against its type
It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. Its MRV returns name it GAZ FIDELITY for 2018–2023 and GAS LISBON for 2024–2025. The reported port of registry changed: Panama (2018–2023), then Monrovia (2024–2025).
Its 2,538 t of CO₂ for 2025 is 58% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 152.3 kg CO₂, 41% below the type median of 256.2 kg. It logged 1,577 hours at sea against a median of 1,943 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2018 (6,108 t) and the lowest 2025 (2,538 t). Its efficiency percentile within the type went from 63 in 2018 to 76 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 222 of 292 qualifying gas carriers by EEOI, at the 76th percentile. The dashed line is the type median, 27.9; this vessel reported 54.5.
EEOI divides emissions by transport work, which for this vessel and year was 46,544,020 tonne-miles over 16,656 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 58.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 25.0% while distance sailed fell 23.4%and CO₂ per nautical mile fell 2.0%.That points mainly to how much the vessel sailed, rather than the other.
