GENER8 GEORGE T against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 79,235 gross tonnage it is larger than 70% 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. Its MRV returns name it GENER8 GEORGE T for 2018 and SIENNA for 2019–2024. The reported port of registry changed: Majuro (2018), then Antwerp (2019–2020), then Monrovia (2022–2024).
Its 5,411 t of CO₂ for 2024 is 34% 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 467.3 kg CO₂, 14% above the type median of 408.2 kg. It logged 930 hours at sea against a median of 2,020 hours for its type that year. 5.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 6 years with reported emissions, the highest was 2020 (7,362 t) and the lowest 2018 (827 t). Its efficiency percentile within the type went from 22 in 2019 to 51 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 802 of 1,566 qualifying oil tankers by EEOI, at the 51st percentile. The dashed line is the type median, 7.6; this vessel reported 7.7.
EEOI divides emissions by transport work, which for this vessel and year was 703,672,302 tonne-miles over 11,580 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 554.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2023 to 2024, emissions fell 23.4% while distance sailed fell 37.9%and CO₂ per nautical mile rose 23.3%.That points mainly to how much the vessel sailed, rather than the other.
