STI SLOANE 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 2018–2025 all give Majuro as port of registry.
Its 4,862 t of CO₂ for 2025 is 39% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 386.8 kg CO₂, close to the type median of 403.2 kg. It logged 1,181 hours at sea against a median of 2,030 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (24,857 t) and the lowest 2018 (4,658 t). Its efficiency percentile within the type went from 23 in 2018 to 6 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 89 of 1,448 qualifying oil tankers by EEOI, at the 6th percentile. The dashed line is the type median, 7.5; this vessel reported 4.0.
EEOI divides emissions by transport work, which for this vessel and year was 1,209,477,612 tonne-miles over 12,570 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 49.2% while distance sailed fell 31.7%and CO₂ per nautical mile fell 25.6%.
