RIAS BAIXAS KNUTSEN 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 121,940 gross tonnage it is larger than 79% of the other 377 LNG carriers with a recorded tonnage. It is one of 10 LNG carriers here under the Spain flag, 1.9% of the 538 on the register. The same builder is recorded for 761 other vessels here, 41 of them LNG carriers. The returns for 2020–2025 all give Santa Cruz de Tenerife as port of registry.
Its 41,136 t of CO₂ for 2025 is 1.9 times the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 516.9 kg CO₂, close to the type median of 533.6 kg. It logged 5,454 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 6 years with reported emissions, the highest was 2025 (41,136 t) and the lowest 2020 (14,120 t). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 191.3% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 11.6% and CO₂ per nautical mile fell 9.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
