VEGA SUN against its type
Built in 2017, it is 4 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 46,250 gross tonnage it is larger than 67% of the other 525 gas carriers with a recorded tonnage. It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. The same builder is recorded for 461 other vessels here, 17 of them gas carriers. The returns for 2019–2025 all give Monrovia as port of registry.
Its 6,789 t of CO₂ for 2025 is 14% above the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 331.4 kg CO₂, 29% above the type median of 256.2 kg. It logged 1,379 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 2020 (8,013 t) and the lowest 2021 (3,001 t). Its efficiency percentile within the type went from 10 in 2019 to 21 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 63 of 292 qualifying gas carriers by EEOI, at the 21st percentile. The dashed line is the type median, 27.9; this vessel reported 16.1.
EEOI divides emissions by transport work, which for this vessel and year was 422,182,836 tonne-miles over 20,483 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 10.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 82.0% while distance sailed rose 98.3%and CO₂ per nautical mile fell 8.2%.That points mainly to how much the vessel sailed, rather than the other.
