NS COLUMBUS 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 57,248 gross tonnage it is smaller than 53% 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 761 other vessels here, 193 of them oil tankers. The returns for 2018–2022 all give Monrovia as port of registry.
Its 5,360 t of CO₂ for 2022 is 25% below the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 415.7 kg CO₂, close to the type median of 415.9 kg. It logged 1,731 hours at sea against a median of 1,731 hours for its type that year. 9.1% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 4 years with reported emissions, the highest was 2018 (19,151 t) and the lowest 2022 (5,360 t). Its efficiency percentile within the type went from 65 in 2018 to 46 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 819 of 1,771 qualifying oil tankers by EEOI, at the 46th percentile. The dashed line is the type median, 8.0; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 698,774,446 tonne-miles over 12,892 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 72.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2021 to 2022, emissions fell 46.0% while distance sailed fell 30.5%and CO₂ per nautical mile fell 22.3%.
