ONYX: CO₂ emissions 2018–2022

ONYX against its type

Built in 2002, it is 8 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 28,553 gross tonnage it is smaller than 82% of the other 2,841 oil tankers with a recorded tonnage. It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The same builder is recorded for 103 other vessels here, 61 of them oil tankers. The returns for 2018–2022 all give Piraeus as port of registry.

Its 12,444 t of CO₂ for 2022 is 1.7 times the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 415.9 kg CO₂, close to the type median of 415.9 kg. It logged 4,246 hours at sea against a median of 1,731 hours for its type that year. 26.4% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2022 (12,444 t) and the lowest 2021 (3,950 t). Its efficiency percentile within the type went from 90 in 2018 to 92 in 2022 (lower is more efficient). Of the 2 sister ships listed below with a 2022 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022

Position 1,629 of 1,771 qualifying oil tankers by EEOI, at the 92nd percentile. The dashed line is the type median, 8.0; this vessel reported 19.7.

EEOI divides emissions by transport work, which for this vessel and year was 632,661,922 tonne-miles over 29,919 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 0.1% higher than in 2018, for EU/EEA voyages only.

From 2021 to 2022, emissions rose 215.1% while distance sailed rose 201.1%and CO₂ per nautical mile rose 4.6%.That points mainly to how much the vessel sailed, rather than the other.
