MIRO against its type

Built in 1998, it is 10 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 16,801 gross tonnage it is smaller than 81% 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 80 other vessels here, 41 of them container ships. Its MRV returns name it MIRO for 2018–2020 and MSC RIONA for 2022. The reported port of registry changed: Majuro (2018–2020), then Monrovia (2022).

Its 4,459 t of CO₂ for 2022 is 71% below the median of 15,388 t among the 1,858 container ships on this register that reported for 2022. Per nautical mile it emitted 327.8 kg CO₂, 39% below the type median of 539.7 kg. It logged 1,463 hours at sea against a median of 2,699 hours for its type that year. 5.3% of its 2022 emissions were at berth; the median for container ships was 4.2%. Across 4 years with reported emissions, the highest was 2018 (12,948 t) and the lowest 2022 (4,459 t). Its efficiency percentile within the type went from 98 in 2018 to 74 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2022

Position 1,183 of 1,589 qualifying container ships by EEOI, at the 74th percentile. The dashed line is the type median, 16.9; this vessel reported 27.4.

EEOI divides emissions by transport work, which for this vessel and year was 163,043,144 tonne-miles over 13,602 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2022 was 65.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2020 to 2022, emissions fell 53.2% while distance sailed fell 51.3%and CO₂ per nautical mile fell 4.0%.That points mainly to how much the vessel sailed, rather than the other.
