DA WEI SHAN against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 7,197 gross tonnage it is smaller than 98% of the other 2,841 oil tankers with a recorded tonnage. It is one of 139 oil tankers here under the Hong Kong flag, 3.9% of the 3,548 on the register. The returns for 2022–2025 all give HONG KONG as port of registry.
Its 371 t of CO₂ for 2025 is 95% 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 128.2 kg CO₂, 68% below the type median of 403.2 kg. It logged 252 hours at sea against a median of 2,030 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 92.6% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 92.6% and CO₂ per nautical mile rose 4.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
