ALPINE PERSEFONE against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 41,696 gross tonnage it is smaller than 65% 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 196 other vessels here, 75 of them oil tankers. Its MRV returns name it ALPINE PERSEFONE for 2019–2023 and TWERK for 2024. The returns for 2019–2024 all give Monrovia as port of registry.
Its 3,595 t of CO₂ for 2024 is 56% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 351.2 kg CO₂, 14% below the type median of 408.2 kg. It logged 1,111 hours at sea against a median of 2,020 hours for its type that year. 4.6% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 4 years with reported emissions, the highest was 2019 (12,268 t) and the lowest 2020 (2,988 t). Its efficiency percentile within the type went from 49 in 2019 to 87 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 1,367 of 1,566 qualifying oil tankers by EEOI, at the 87th percentile. The dashed line is the type median, 7.6; this vessel reported 15.1.
EEOI divides emissions by transport work, which for this vessel and year was 238,534,837 tonne-miles over 10,236 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 70.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2023 to 2024, emissions fell 46.8% while distance sailed fell 34.0%and CO₂ per nautical mile fell 19.3%.That points mainly to how much the vessel sailed, rather than the other.
