CASTILLO DE MONTERREAL against its type
Built in 2002, it is 8 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 21,682 gross tonnage it is smaller than 92% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2018–2021 all give Valletta as port of registry.
Its 12,748 t of CO₂ for 2021 is 1.7 times the median of 7,717 t among the 1,777 oil tankers on this register that reported for 2021. Per nautical mile it emitted 457.4 kg CO₂, 12% above the type median of 409.1 kg. It logged 3,679 hours at sea against a median of 1,921 hours for its type that year. 26.6% of its 2021 emissions were at berth; the median for oil tankers was 8.8%. Across 4 years with reported emissions, the highest was 2019 (12,770 t) and the lowest 2020 (11,346 t). Its efficiency percentile within the type went from 95 in 2018 to 99 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2021
Position 1,615 of 1,636 qualifying oil tankers by EEOI, at the 99th percentile. The dashed line is the type median, 8.4; this vessel reported 41.5.
EEOI divides emissions by transport work, which for this vessel and year was 307,474,433 tonne-miles over 27,870 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 3.9% higher than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions rose 12.4% while distance sailed fell 6.1%and CO₂ per nautical mile rose 19.6%.That points mainly to how efficiently it sailed, rather than the other.
