RIOJA KNUTSEN against its type
Built in 2016, it is 2 years newer than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 116,246 gross tonnage it is larger than 71% 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.
Its 64,586 t of CO₂ for 2025 is 3.0 times the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 597.6 kg CO₂, 12% above the type median of 533.6 kg. It logged 7,662 hours at sea against a median of 2,940 hours for its type that year. 1.4% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 8 years with reported emissions, the highest was 2025 (64,586 t) and the lowest 2019 (13,154 t). Of the 4 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 241.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 1.4% and CO₂ per nautical mile rose 1.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
