JAG LYALL 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 MRV returns name it JAG LYALL for 2019–2021 and ROYALL for 2022. The reported port of registry changed: Mumbai (2019–2021), then MONROVIA (2022).
Its 3,214 t of CO₂ for 2022 is 55% below the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 439.1 kg CO₂, close to the type median of 415.9 kg. It logged 625 hours at sea against a median of 1,731 hours for its type that year. 4.7% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 4 years with reported emissions, the highest was 2019 (7,675 t) and the lowest 2021 (3,069 t). Its efficiency percentile within the type went from 38 in 2019 to 33 in 2022 (lower is more efficient). The one comparable vessel listed below with a 2022 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2022
Position 578 of 1,771 qualifying oil tankers by EEOI, at the 33rd percentile. The dashed line is the type median, 8.0; this vessel reported 6.5.
EEOI divides emissions by transport work, which for this vessel and year was 491,408,257 tonne-miles over 7,320 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 58.1% lower than in 2019, for EU/EEA voyages only.
From 2021 to 2022, emissions rose 4.7% and CO₂ per nautical mile fell 4.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
