LIBERTY PROMISE against its type
Built in 2010, it is 2 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 57,030 gross tonnage it is smaller than 65% of the other 571 vehicle carriers with a recorded tonnage. It is one of 23 vehicle carriers here under the United States flag, 3.2% of the 713 on the register. The same builder is recorded for 660 other vessels here, 45 of them vehicle carriers. The returns for 2018–2022 all give New York as port of registry.
Its 6,046 t of CO₂ for 2022 is 27% below the median of 8,301 t among the 462 vehicle carriers on this register that reported for 2022. Per nautical mile it emitted 326.0 kg CO₂, close to the type median of 336.8 kg. It logged 1,126 hours at sea against a median of 1,694 hours for its type that year. 1.5% of its 2022 emissions were at berth; the median for vehicle carriers was 4.0%. Across 5 years with reported emissions, the highest was 2019 (9,007 t) and the lowest 2018 (4,295 t). Its efficiency percentile within the type went from 28 in 2018 to 21 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 90 of 416 qualifying vehicle carriers by EEOI, at the 21st percentile. The dashed line is the type median, 54.7; this vessel reported 44.0.
EEOI divides emissions by transport work, which for this vessel and year was 137,386,276 tonne-miles over 18,549 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 40.8% higher than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions rose 32.5% while distance sailed rose 43.6%and CO₂ per nautical mile fell 7.8%.That points mainly to how much the vessel sailed, rather than the other.
