MARVEL HERON against its type
Built in 2019, it is 5 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 139,050 gross tonnage it is larger than 94% of the other 377 LNG carriers with a recorded tonnage. It is one of 28 LNG carriers here under the Panama flag, 5.2% of the 538 on the register. The returns for 2019–2024 all give PANAMA as port of registry.
Its 14,101 t of CO₂ for 2024 is 10% below the median of 15,704 t among the 348 LNG carriers on this register that reported for 2024. Per nautical mile it emitted 620.4 kg CO₂, 12% above the type median of 552.7 kg. It logged 1,603 hours at sea against a median of 2,215 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for LNG carriers was 1.6%. Across 4 years with reported emissions, the highest was 2024 (14,101 t) and the lowest 2022 (6,903 t). Of the 3 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2024 was 56.2% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.
From 2022 to 2024, emissions rose 104.3% and CO₂ per nautical mile fell 2.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
