NAVIOS UNISON against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 113,412 gross tonnage it is larger than 83% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 563 other vessels here, 243 of them container ships. The returns for 2018–2020 all give MONROVIA as port of registry.
Its 6,030 t of CO₂ for 2020 is 64% below the median of 16,763 t among the 1,837 container ships on this register that reported for 2020. Per nautical mile it emitted 980.8 kg CO₂, 1.8 times the type median of 536.8 kg. It logged 448 hours at sea against a median of 2,806 hours for its type that year. 5.5% of its 2020 emissions were at berth; the median for container ships was 3.7%. Across 3 years with reported emissions, the highest was 2019 (27,070 t) and the lowest 2020 (6,030 t). Its efficiency percentile within the type went from 91 in 2018 to 34 in 2020 (lower is more efficient).

Efficiency against its own type2020
Position 522 of 1,525 qualifying container ships by EEOI, at the 34th percentile. The dashed line is the type median, 15.9; this vessel reported 12.3.
EEOI divides emissions by transport work, which for this vessel and year was 491,057,818 tonne-miles over 6,148 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2020 was 56.5% lower than in 2018, for EU/EEA voyages only.
From 2019 to 2020, emissions fell 77.7% while distance sailed fell 79.2%and CO₂ per nautical mile rose 7.1%.That points mainly to how much the vessel sailed, rather than the other.
