KNEBWORTH against its type
Built in 2012, it is 1 year older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 7,891 gross tonnage it is smaller than 85% of the other 525 gas carriers with a recorded tonnage. It is one of 106 gas carriers here under the Singapore flag, 15.4% of the 688 on the register. The same builder is recorded for 24 other vessels here, 5 of them gas carriers. The returns for 2018–2025 all give Singapore as port of registry.
Its 418 t of CO₂ for 2025 is 93% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 179.7 kg CO₂, 30% below the type median of 256.2 kg. It logged 428 hours at sea against a median of 1,943 hours for its type that year. 3.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 7 years with reported emissions, the highest was 2023 (6,978 t) and the lowest 2025 (418 t). Its efficiency percentile within the type went from 75 in 2018 to 79 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 90.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions fell 89.8% and CO₂ per nautical mile fell 15.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
