GAZ SERENITY against its type
Built in 2010, it is 3 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 16,777 gross tonnage it is smaller than 68% of the other 525 gas carriers with a recorded tonnage. It is one of 99 gas carriers here under the Panama flag, 14.4% of the 688 on the register. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The returns for 2018–2025 all give Panama as port of registry.
Its 2,040 t of CO₂ for 2025 is 66% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 288.4 kg CO₂, 13% above the type median of 256.2 kg. It logged 852 hours at sea against a median of 1,943 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2021 (19,239 t) and the lowest 2025 (2,040 t). Its efficiency percentile within the type went from 63 in 2018 to 56 in 2024 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 70.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 35.4% and CO₂ per nautical mile fell 6.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
