SILVER GWEN against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,553 gross tonnage it is larger than 76% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 761 other vessels here, 4 of them chemical tankers. The returns for 2018–2021 all give Panama as port of registry.
Its 2,832 t of CO₂ for 2021 is 53% below the median of 6,071 t among the 1,418 chemical tankers on this register that reported for 2021. Per nautical mile it emitted 285.7 kg CO₂, close to the type median of 262.7 kg. It logged 818 hours at sea against a median of 2,112 hours for its type that year. 20.0% of its 2021 emissions were at berth; the median for chemical tankers was 8.4%. Across 3 years with reported emissions, the highest was 2018 (4,614 t) and the lowest 2020 (2,521 t). Its efficiency percentile within the type went from 4 in 2020 to 6 in 2021 (lower is more efficient).

Efficiency against its own type2021
Position 78 of 1,261 qualifying chemical tankers by EEOI, at the 6th percentile. The dashed line is the type median, 16.1; this vessel reported 8.5.
EEOI divides emissions by transport work, which for this vessel and year was 333,971,698 tonne-miles over 9,913 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 38.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2020 to 2021, emissions rose 12.3% while distance sailed rose 9.5%and CO₂ per nautical mile rose 2.5%.That points mainly to how much the vessel sailed, rather than the other.
Where the 2021 emissions occurred
Laden voyages2021
- CO₂ on laden voyages
