ALULAR against its type
It is one of 59 gas carriers here under the Malta flag, 8.6% of the 688 on the register. Its MRV returns name it JS ALULAR for 2018–2022, ALULAR for 2023 and CGAS LEOPARD for 2024–2025. The reported port of registry changed: Singapore (2018–2023), then Valetta (2024), then VALLETTA (2025).
Its 4,860 t of CO₂ for 2025 is 19% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 143.6 kg CO₂, 44% below the type median of 256.2 kg. It logged 3,125 hours at sea against a median of 1,943 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2019 (7,000 t) and the lowest 2022 (4,124 t). Its efficiency percentile within the type went from 80 in 2018 to 93 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 272 of 292 qualifying gas carriers by EEOI, at the 93rd percentile. The dashed line is the type median, 27.9; this vessel reported 111.0.
EEOI divides emissions by transport work, which for this vessel and year was 43,782,973 tonne-miles over 33,846 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 9.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 9.5% while distance sailed rose 12.3%and CO₂ per nautical mile fell 2.4%.That points mainly to how much the vessel sailed, rather than the other.
