VANGUARD against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 87,146 gross tonnage it is larger than 86% of the other 2,841 oil tankers with a recorded tonnage. It is one of 3 oil tankers here under the Oman flag, 0.1% of the 3,548 on the register. The same builder is recorded for 660 other vessels here, 159 of them oil tankers. The returns for 2018–2021 all give Monrovia as port of registry.
Its 4,224 t of CO₂ for 2021 is 45% 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 730.0 kg CO₂, 1.8 times the type median of 409.1 kg. It logged 529 hours at sea against a median of 1,921 hours for its type that year. 38.1% 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 (23,273 t) and the lowest 2021 (4,224 t). Its efficiency percentile within the type went from 31 in 2018 to 48 in 2021 (lower is more efficient). The one sister ship listed below with a 2021 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2021
Position 780 of 1,636 qualifying oil tankers by EEOI, at the 48th percentile. The dashed line is the type median, 8.4; this vessel reported 8.1.
EEOI divides emissions by transport work, which for this vessel and year was 518,895,577 tonne-miles over 5,786 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 81.9% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 77.0% while distance sailed fell 79.0%and CO₂ per nautical mile rose 9.6%.That points mainly to how much the vessel sailed, rather than the other.
