TOPAZ against its type
Built in 2004, it is 6 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 27,725 gross tonnage it is smaller than 85% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2018–2021 all give Monrovia as port of registry.
Its 2,040 t of CO₂ for 2021 is 74% 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 285.4 kg CO₂, 30% below the type median of 409.1 kg. It logged 588 hours at sea against a median of 1,921 hours for its type that year. 3.4% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2020 (10,912 t) and the lowest 2021 (2,040 t). Its efficiency percentile within the type went from 69 in 2018 to 73 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2021
Position 1,200 of 1,636 qualifying oil tankers by EEOI, at the 73rd percentile. The dashed line is the type median, 8.4; this vessel reported 11.9.
EEOI divides emissions by transport work, which for this vessel and year was 170,703,766 tonne-miles over 7,147 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 47.0% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 81.3% while distance sailed fell 80.7%and CO₂ per nautical mile fell 3.3%.That points mainly to how much the vessel sailed, rather than the other.
