NORSTAR INVICTUS against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,010 gross tonnage it is smaller than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The returns for 2018–2021 all give Majuro as port of registry.
Its 3,892 t of CO₂ for 2021 is 50% 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 369.1 kg CO₂, close to the type median of 409.1 kg. It logged 924 hours at sea against a median of 1,921 hours for its type that year. 21.6% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 3 years with reported emissions, the highest was 2018 (6,780 t) and the lowest 2021 (3,892 t). Its efficiency percentile within the type went from 66 in 2018 to 81 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2021
Position 1,325 of 1,636 qualifying oil tankers by EEOI, at the 81st percentile. The dashed line is the type median, 8.4; this vessel reported 14.6.
EEOI divides emissions by transport work, which for this vessel and year was 266,913,580 tonne-miles over 10,545 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 42.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2019 to 2021, emissions fell 12.9% while distance sailed rose 48.2%and CO₂ per nautical mile fell 41.2%.
