BETTY KNUTSEN against its type
Built in 1999, it is 11 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 24,185 gross tonnage it is smaller than 88% of the other 2,841 oil tankers with a recorded tonnage. It is one of 58 oil tankers here under the Norway flag, 1.6% of the 3,548 on the register. The same builder is recorded for 9 other vessels here, 3 of them oil tankers. The returns for 2018–2021 all give Haugesund as port of registry.
Its 6,216 t of CO₂ for 2021 is 19% below the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 697.0 kg CO₂, 1.7 times the type median of 409.1 kg. It logged 988 hours at sea against a median of 1,921 hours for its type that year. 8.4% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2018 (14,727 t) and the lowest 2021 (6,216 t). The one comparable vessel listed below with a 2021 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2021 was 57.8% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 47.0% and CO₂ per nautical mile fell 11.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
