COOL VOYAGER against its type
Built in 2013, it is 1 year older than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 102,097 gross tonnage it is smaller than 71% of the other 377 LNG carriers with a recorded tonnage. It is one of 60 LNG carriers here under the Malta flag, 11.2% of the 538 on the register. The same builder is recorded for 563 other vessels here, 82 of them LNG carriers. The reported port of registry changed: Valetta (2021), then Valletta (2022), then Valetta (2023–2025).
Its 9,962 t of CO₂ for 2025 is 54% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 507.9 kg CO₂, close to the type median of 533.6 kg. It logged 1,607 hours at sea against a median of 2,940 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 4 years with reported emissions, the highest was 2023 (24,300 t) and the lowest 2025 (9,962 t). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 18.1% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 59.0% and CO₂ per nautical mile fell 27.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
