LR2 POLARIS 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 59,172 gross tonnage it is smaller than 50% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The same builder is recorded for 103 other vessels here, 28 of them oil tankers. Its MRV returns name it LR2 POLARIS for 2018–2019 and POLARIS BAY for 2021–2022. The reported port of registry changed: Hong Kong (2018–2019), then MONROVIA (2021–2022).
Its 16,201 t of CO₂ for 2022 is 2.3 times the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 443.8 kg CO₂, close to the type median of 415.9 kg. It logged 3,429 hours at sea against a median of 1,731 hours for its type that year. 8.7% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 4 years with reported emissions, the highest was 2022 (16,201 t) and the lowest 2019 (4,740 t). Its efficiency percentile within the type went from 15 in 2018 to 29 in 2022 (lower is more efficient). Of the 4 sister ships listed below with a 2022 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 512 of 1,771 qualifying oil tankers by EEOI, at the 29th percentile. The dashed line is the type median, 8.0; this vessel reported 6.2.
EEOI divides emissions by transport work, which for this vessel and year was 2,592,160,000 tonne-miles over 36,503 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 129.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2021 to 2022, emissions rose 214.1% while distance sailed rose 215.8%and CO₂ per nautical mile fell 0.5%.That points mainly to how much the vessel sailed, rather than the other.
