MINERVA CLARA 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 58,156 gross tonnage it is smaller than 51% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 563 other vessels here, 217 of them oil tankers. The reported port of registry changed: Piraeus (2018–2023), then Monrovia (2024–2025).
Its 14 t of CO₂ for 2025 is 100% 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 1,185.5 kg CO₂, 2.9 times the type median of 403.2 kg. It logged 10 hours at sea against a median of 2,030 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2019 (22,378 t) and the lowest 2025 (14 t). Its efficiency percentile within the type went from 29 in 2018 to 67 in 2024 (lower is more efficient).

Reported CO₂ by year
Reported CO₂ in 2025 was 99.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 99.9% and CO₂ per nautical mile rose 141.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
