RIDGEBURY MARY SELENA against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 77,636 gross tonnage it is larger than 69% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The returns for 2018–2021 all give Majuro as port of registry.
Its 17,544 t of CO₂ for 2021 is 2.3 times the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 561.2 kg CO₂, 37% above the type median of 409.1 kg. It logged 2,852 hours at sea against a median of 1,921 hours for its type that year. 6.6% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2021 (17,544 t) and the lowest 2018 (3,713 t). Its efficiency percentile within the type went from 25 in 2018 to 14 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2021
Position 237 of 1,636 qualifying oil tankers by EEOI, at the 14th percentile. The dashed line is the type median, 8.4; this vessel reported 5.1.
EEOI divides emissions by transport work, which for this vessel and year was 3,446,807,466 tonne-miles over 31,263 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 372.5% higher than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions rose 70.8% while distance sailed rose 78.0%and CO₂ per nautical mile fell 4.1%.That points mainly to how much the vessel sailed, rather than the other.
