ECO NEBULA against its type
Built in 2007, it is 6 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 25,937 gross tonnage it is larger than 56% of the other 525 gas carriers with a recorded tonnage. It is one of 2 gas carriers here under the South Korea flag, 0.3% of the 688 on the register. The same builder is recorded for 660 other vessels here, 20 of them gas carriers. Its MRV returns name it ECO NEBULA for 2019–2021, MANTA SALACAK for 2022–2023 and GREEN ONE for 2024. The reported port of registry changed: MONROVIA (2019–2021), then JEJU (2024).
Its 858 t of CO₂ for 2024 is 86% below the median of 6,198 t among the 333 gas carriers on this register that reported for 2024. Per nautical mile it emitted 449.9 kg CO₂, 1.8 times the type median of 252.4 kg. It logged 421 hours at sea against a median of 2,165 hours for its type that year. 4.5% of its 2024 emissions were at berth; the median for gas carriers was 3.5%. Across 6 years with reported emissions, the highest was 2020 (16,169 t) and the lowest 2023 (373 t). Its efficiency percentile within the type went from 16 in 2019 to 0 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 2 of 279 qualifying gas carriers by EEOI, at the 0th percentile. The dashed line is the type median, 34.6; this vessel reported 8.9.
EEOI divides emissions by transport work, which for this vessel and year was 96,298,541 tonne-miles over 1,907 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 84.6% lower than in 2019, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 130.1% and CO₂ per nautical mile rose 47.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
