ROC: CO₂ emissions 2018–2023

ROC 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 42,172 gross tonnage it is smaller than 63% of the other 2,841 oil tankers with a recorded tonnage. It is one of 10 oil tankers here under the Gibraltar flag, 0.3% of the 3,548 on the register. Its MRV returns name it ENERGY CONQUEROR for 2018 and CONQUEROR for 2019–2023. The reported port of registry changed: Douglas (2018), then Gibraltar (2019–2023).

Its 5,911 t of CO₂ for 2023 is 21% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 404.1 kg CO₂, close to the type median of 408.5 kg. It logged 2,003 hours at sea against a median of 1,807 hours for its type that year. 1.4% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 5 years with reported emissions, the highest was 2019 (17,016 t) and the lowest 2023 (5,911 t). Its efficiency percentile within the type went from 85 in 2018 to 82 in 2023 (lower is more efficient). Of the 2 comparable vessels listed below with a 2023 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023

Position 1,320 of 1,615 qualifying oil tankers by EEOI, at the 82nd percentile. The dashed line is the type median, 8.0; this vessel reported 13.2.

EEOI divides emissions by transport work, which for this vessel and year was 446,814,059 tonne-miles over 14,628 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2023 was 56.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2022 to 2023, emissions fell 49.3% while distance sailed fell 50.4%and CO₂ per nautical mile rose 2.3%.That points mainly to how much the vessel sailed, rather than the other.
