CHEM WOLVERINE against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,561 gross tonnage it is smaller than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The returns for 2018–2021 all give MAJURO as port of registry.
Its 1,518 t of CO₂ for 2021 is 75% 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 197.9 kg CO₂, 25% below the type median of 262.7 kg. It logged 656 hours at sea against a median of 2,112 hours for its type that year. 1.5% of its 2021 emissions were at berth; the median for chemical tankers was 8.4%. Across 4 years with reported emissions, the highest was 2019 (2,778 t) and the lowest 2018 (1,435 t). Its efficiency percentile within the type went from 20 in 2018 to 26 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2021
Position 332 of 1,261 qualifying chemical tankers by EEOI, at the 26th percentile. The dashed line is the type median, 16.1; this vessel reported 12.0.
EEOI divides emissions by transport work, which for this vessel and year was 126,297,837 tonne-miles over 7,673 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 5.8% higher than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 18.3% while distance sailed fell 12.4%and CO₂ per nautical mile fell 6.7%.That points mainly to how much the vessel sailed, rather than the other.
