CORAL SHASTA against its type
Built in 2003, it is 10 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 9,691 gross tonnage it is smaller than 78% 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 204 other vessels here, 5 of them gas carriers. Its MRV returns name it NORGAS SHASTA for 2018 and CORAL SHASTA for 2021–2025. The reported port of registry changed: Singapore (2018–2022), then Monrovia (2023–2025).
Its 14,625 t of CO₂ for 2025 is 2.4 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 263.1 kg CO₂, close to the type median of 256.2 kg. It logged 5,085 hours at sea against a median of 1,943 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 6 years with reported emissions, the highest was 2025 (14,625 t) and the lowest 2018 (2,483 t). Its efficiency percentile within the type went from 93 in 2021 to 92 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 270 of 292 qualifying gas carriers by EEOI, at the 92nd percentile. The dashed line is the type median, 27.9; this vessel reported 107.9.
EEOI divides emissions by transport work, which for this vessel and year was 135,515,104 tonne-miles over 55,591 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 489.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions rose 30.5% while distance sailed rose 41.9%and CO₂ per nautical mile fell 8.0%.That points mainly to how much the vessel sailed, rather than the other.
