WONDER MIMOSA 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. Its MRV returns name it SIKINOS for 2018–2020 and WONDER MIMOSA for 2021–2025. The reported port of registry changed: Piraeus (2018–2020), then Majuro (2021–2025).
Its 12,647 t of CO₂ for 2025 is 1.6 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 419.2 kg CO₂, close to the type median of 403.2 kg. It logged 6,175 hours at sea against a median of 2,030 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2019 (16,091 t) and the lowest 2021 (5,857 t). Its efficiency percentile within the type went from 72 in 2018 to 98 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,414 of 1,448 qualifying oil tankers by EEOI, at the 98th percentile. The dashed line is the type median, 7.5; this vessel reported 30.3.
EEOI divides emissions by transport work, which for this vessel and year was 416,971,975 tonne-miles over 30,165 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 19.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 17.0% while distance sailed rose 18.8%and CO₂ per nautical mile fell 1.5%.That points mainly to how much the vessel sailed, rather than the other.
