KOKSIJDE against its type
Built in 2018, it is 5 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 25,952 gross tonnage it is larger than 56% of the other 525 gas carriers with a recorded tonnage. It is one of 15 gas carriers here under the Belgium flag, 2.2% of the 688 on the register. The same builder is recorded for 74 other vessels here, 3 of them gas carriers. The reported port of registry changed: Antwerp (2019), then ANTWERPEN (2020), then Antwerp (2021), then ANTWERPEN (2022), then Antwerp (2023), then Antwerpen (2024–2025).
Its 17,778 t of CO₂ for 2025 is 3.0 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 307.8 kg CO₂, 20% above the type median of 256.2 kg. It logged 4,302 hours at sea against a median of 1,943 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2025 (17,778 t) and the lowest 2018 (2,081 t). Its efficiency percentile within the type went from 45 in 2019 to 54 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 158 of 292 qualifying gas carriers by EEOI, at the 54th percentile. The dashed line is the type median, 27.9; this vessel reported 30.9.
EEOI divides emissions by transport work, which for this vessel and year was 575,139,114 tonne-miles over 57,753 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 754.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 6.4% while distance sailed rose 0.7%and CO₂ per nautical mile rose 5.6%.That points mainly to how efficiently it sailed, rather than the other.
