SILVER ERVILIA against its type
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 2018–2022 all give Majuro as port of registry.
Its 8,470 t of CO₂ for 2022 is 18% above the median of 7,189 t among the 1,939 oil tankers on this register that reported for 2022. Per nautical mile it emitted 215.9 kg CO₂, 48% below the type median of 415.9 kg. It logged 3,276 hours at sea against a median of 1,731 hours for its type that year. 5.0% of its 2022 emissions were at berth; the median for oil tankers was 9.1%. Across 5 years with reported emissions, the highest was 2018 (9,026 t) and the lowest 2020 (2,001 t). Its efficiency percentile within the type went from 55 in 2018 to 74 in 2022 (lower is more efficient).

Efficiency against its own type2022
Position 1,322 of 1,771 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 8.0; this vessel reported 11.3.
EEOI divides emissions by transport work, which for this vessel and year was 746,915,344 tonne-miles over 39,231 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 6.2% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions rose 130.3% while distance sailed rose 152.3%and CO₂ per nautical mile fell 8.7%.That points mainly to how much the vessel sailed, rather than the other.
