KALLO against its type
It is one of 15 gas carriers here under the Belgium flag, 2.2% of the 688 on the register. The reported port of registry changed: Antwerp (2019), then ANTWERPEN (2022–2025).
Its 2,390 t of CO₂ for 2025 is 60% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 229.6 kg CO₂, 10% below the type median of 256.2 kg. It logged 860 hours at sea against a median of 1,943 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 5 years with reported emissions, the highest was 2018 (5,572 t) and the lowest 2022 (1,439 t). Its efficiency percentile within the type went from 12 in 2018 to 34 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 101 of 292 qualifying gas carriers by EEOI, at the 34th percentile. The dashed line is the type median, 27.9; this vessel reported 20.5.
EEOI divides emissions by transport work, which for this vessel and year was 116,374,391 tonne-miles over 10,410 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 7.3% while distance sailed rose 18.2%and CO₂ per nautical mile fell 21.6%.
