LR1 AMBASSADOR against its type
It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register.
Its 7,156 t of CO₂ for 2024 is 13% 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 405.8 kg CO₂, close to the type median of 408.2 kg. It logged 1,565 hours at sea against a median of 2,020 hours for its type that year. 6.4% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Its efficiency percentile within the type went from 52 in 2019 to 76 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 1,199 of 1,566 qualifying oil tankers by EEOI, at the 76th percentile. The dashed line is the type median, 7.6; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 671,274,859 tonne-miles over 17,634 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 231.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2019 to 2024, emissions rose 231.3% while distance sailed rose 357.9%and CO₂ per nautical mile fell 27.6%.That points mainly to how much the vessel sailed, rather than the other.
