AST SUNSHINE 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 AST SUNSHINE for 2020–2021 and STENA SUNSHINE for 2022–2025. The returns for 2020–2025 all give Panama as port of registry.

Its 7,243 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 401.8 kg CO₂, close to the type median of 403.2 kg. It logged 1,753 hours at sea against a median of 2,030 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2023 (12,135 t) and the lowest 2022 (2,641 t). Its efficiency percentile within the type went from 27 in 2020 to 38 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 49.0% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions fell 40.3% while distance sailed fell 36.7%and CO₂ per nautical mile fell 5.7%.That points mainly to how much the vessel sailed, rather than the other.
