THUN LONDON against its type
Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,826 gross tonnage it is smaller than 72% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 15 chemical tankers here under the Netherlands flag, 0.6% of the 2,344 on the register. The same builder is recorded for 40 other vessels here, 32 of them chemical tankers. The returns for 2019–2025 all give Delfzijl as port of registry.
Its 1,138 t of CO₂ for 2025 is 79% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 222.5 kg CO₂, 11% below the type median of 250.2 kg. It logged 564 hours at sea against a median of 2,109 hours for its type that year. 28.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2020 (6,056 t) and the lowest 2023 (942 t). Its efficiency percentile within the type went from 30 in 2019 to 79 in 2020 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 73.2% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 12.6% and CO₂ per nautical mile rose 24.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
