INEOS INVENTION 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 INEOS INVENTION for 2018–2022 and INEOS INVENTION for 2023–2025. The returns for 2019–2025 all give Valletta as port of registry.
Its 21,104 t of CO₂ for 2025 is 3.5 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 236.4 kg CO₂, close to the type median of 256.2 kg. It logged 6,230 hours at sea against a median of 1,943 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2020 (24,165 t) and the lowest 2022 (7,311 t). Its efficiency percentile within the type went from 25 in 2018 to 53 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 155 of 292 qualifying gas carriers by EEOI, at the 53rd percentile. The dashed line is the type median, 27.9; this vessel reported 30.4.
EEOI divides emissions by transport work, which for this vessel and year was 693,524,154 tonne-miles over 89,276 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 9.9% while distance sailed fell 10.0%and CO₂ per nautical mile rose 0.1%.That points mainly to how much the vessel sailed, rather than the other.
