PACIFIC ONYX against its type
Built in 2013, it is 3 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 28,426 gross tonnage it is smaller than 82% 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 103 other vessels here, 61 of them oil tankers. The returns for 2018–2023 all give Monrovia as port of registry.
Its 7,888 t of CO₂ for 2023 is close to the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 312.7 kg CO₂, 23% below the type median of 408.5 kg. It logged 2,224 hours at sea against a median of 1,807 hours for its type that year. 9.3% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 4 years with reported emissions, the highest was 2023 (7,888 t) and the lowest 2021 (1,760 t). Its efficiency percentile within the type went from 60 in 2018 to 79 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2023
Position 1,275 of 1,615 qualifying oil tankers by EEOI, at the 79th percentile. The dashed line is the type median, 8.0; this vessel reported 12.2.
EEOI divides emissions by transport work, which for this vessel and year was 646,012,285 tonne-miles over 25,222 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 262.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2022 to 2023, emissions rose 146.1% while distance sailed rose 101.4%and CO₂ per nautical mile rose 22.2%.That points mainly to how much the vessel sailed, rather than the other.
