KAREN 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 88,109 gross tonnage it is larger than 86% of the other 2,841 oil tankers with a recorded tonnage. The same builder is recorded for 761 other vessels here, 193 of them oil tankers.
Its 9,783 t of CO₂ for 2020 is 12% above the median of 8,732 t among the 1,884 oil tankers on this register that reported for 2020. Per nautical mile it emitted 772.4 kg CO₂, 1.8 times the type median of 424.6 kg. It logged 1,696 hours at sea against a median of 1,939 hours for its type that year. 7.1% of its 2020 emissions were at berth; the median for oil tankers was 8.6%. Across 3 years with reported emissions, the highest was 2018 (25,783 t) and the lowest 2020 (9,783 t). Its efficiency percentile within the type went from 95 in 2018 to 97 in 2020 (lower is more efficient). The one sister ship listed below with a 2020 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2020
Position 1,660 of 1,708 qualifying oil tankers by EEOI, at the 97th percentile. The dashed line is the type median, 8.7; this vessel reported 32.8.
EEOI divides emissions by transport work, which for this vessel and year was 298,705,344 tonne-miles over 12,666 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2020 was 62.1% lower than in 2018, for EU/EEA voyages only.
From 2019 to 2020, emissions fell 51.4% and CO₂ per nautical mile fell 38.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
