STAR MERLIN against its type
It is one of 29 oil tankers here under the Cyprus flag, 0.8% of the 3,548 on the register. The reported port of registry changed: Majuro (2019), then Panama (2020–2021), then Madeira (2022–2023), then Limassol (2024–2025).
Its 5,912 t of CO₂ for 2025 is 25% 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 307.7 kg CO₂, 24% below the type median of 403.2 kg. It logged 1,884 hours at sea against a median of 2,030 hours for its type that year. 8.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2022 (6,630 t) and the lowest 2024 (963 t). Its efficiency percentile within the type went from 65 in 2019 to 77 in 2025 (lower is more efficient).

Efficiency against its own type2025
Position 1,114 of 1,448 qualifying oil tankers by EEOI, at the 77th percentile. The dashed line is the type median, 7.5; this vessel reported 10.9.
EEOI divides emissions by transport work, which for this vessel and year was 544,422,652 tonne-miles over 19,215 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 113.3% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 514.0% and CO₂ per nautical mile fell 2.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
