NS BRAVO against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 83,747 gross tonnage it is larger than 81% 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 same builder is recorded for 34 other vessels here, 20 of them oil tankers. The returns for 2018–2021 all give Monrovia as port of registry.
Its 3,166 t of CO₂ for 2021 is 59% 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 442.5 kg CO₂, close to the type median of 409.1 kg. It logged 949 hours at sea against a median of 1,921 hours for its type that year. 9.2% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2019 (20,059 t) and the lowest 2021 (3,166 t). Its efficiency percentile within the type went from 32 in 2018 to 36 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 586 of 1,636 qualifying oil tankers by EEOI, at the 36th percentile. The dashed line is the type median, 8.4; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 452,345,714 tonne-miles over 7,156 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 83.3% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 21.1% while distance sailed fell 5.6%and CO₂ per nautical mile fell 16.4%.That points mainly to how efficiently it sailed, rather than the other.
