RIO BARROW against its type
Built in 2001, it is 7 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 65,059 gross tonnage it is larger than 59% 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 761 other vessels here, 355 of them container ships. Hapag-Lloyd is linked to 28 vessels on this register. Its MRV returns name it RIO BARROW for 2020 and TONSBERG for 2021. The returns for 2020–2021 all give MONROVIA as port of registry.
Its 7,781 t of CO₂ for 2021 is 52% below the median of 16,246 t among the 1,825 container ships on this register that reported for 2021. Per nautical mile it emitted 789.0 kg CO₂, 40% above the type median of 562.2 kg. It logged 618 hours at sea against a median of 2,808 hours for its type that year. 2.8% of its 2021 emissions were at berth; the median for container ships was 3.9%. Its efficiency percentile within the type went from 48 in 2020 to 56 in 2021 (lower is more efficient).

Efficiency against its own type2021
Position 879 of 1,557 qualifying container ships by EEOI, at the 56th percentile. The dashed line is the type median, 16.2; this vessel reported 18.2.
Across the 24 ranked vessels operated by Hapag-Lloyd, the median percentile is 29. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 426,602,522 tonne-miles over 9,862 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 67.9% higher than in 2020, for EU/EEA voyages only.
From 2020 to 2021, emissions rose 67.9% while distance sailed rose 57.3%and CO₂ per nautical mile rose 6.7%.That points mainly to how much the vessel sailed, rather than the other.
