C VALENTINE against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 30,068 gross tonnage it is smaller than 71% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. Its MRV returns name it C VALENTINE for 2018 and JADE BLOSSOM for 2022–2023. The reported port of registry changed: Majuro, Marshall Islands (2018), then Majuro (2022–2023).
Its 5,949 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 340.5 kg CO₂, 17% below the type median of 408.5 kg. It logged 1,627 hours at sea against a median of 1,807 hours for its type that year. 6.5% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 3 years with reported emissions, the highest was 2022 (18,469 t) and the lowest 2018 (5,684 t). Its efficiency percentile within the type went from 39 in 2018 to 62 in 2023 (lower is more efficient). Of the 3 comparable vessels listed below with a 2023 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 996 of 1,615 qualifying oil tankers by EEOI, at the 62nd percentile. The dashed line is the type median, 8.0; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 650,169,399 tonne-miles over 17,472 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 4.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2022 to 2023, emissions fell 67.8% while distance sailed fell 66.4%and CO₂ per nautical mile fell 4.3%.That points mainly to how much the vessel sailed, rather than the other.
