CHASELKA against its type
It is one of 244 oil tankers here under the Panama flag, 6.9% of the 3,548 on the register. Its MRV returns name it CHASELKA for 2018–2021, LR2 APHRODITE for 2022 and VST AMARA for 2024–2025. The reported port of registry changed: Hong kong (2018–2022), then Panama (2024–2025).
Its 11,308 t of CO₂ for 2025 is 43% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 414.4 kg CO₂, close to the type median of 403.2 kg. It logged 2,512 hours at sea against a median of 2,030 hours for its type that year. 5.0% 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 (12,049 t) and the lowest 2018 (1,650 t). Its efficiency percentile within the type went from 8 in 2019 to 13 in 2025 (lower is more efficient). Of the 8 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 188 of 1,448 qualifying oil tankers by EEOI, at the 13th percentile. The dashed line is the type median, 7.5; this vessel reported 4.7.
EEOI divides emissions by transport work, which for this vessel and year was 2,431,838,710 tonne-miles over 27,285 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 585.5% 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 161.0% while distance sailed rose 116.2%and CO₂ per nautical mile rose 20.8%.That points mainly to how much the vessel sailed, rather than the other.
