MIRAI against its type

It is one of 70 gas carriers here under the Marshall Islands flag, 10.2% of the 688 on the register. The returns for 2023–2025 all give Majuro as port of registry.

Its 14,581 t of CO₂ for 2025 is 2.4 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 260.9 kg CO₂, close to the type median of 256.2 kg. It logged 3,698 hours at sea against a median of 1,943 hours for its type that year. 10.8% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 3 years with reported emissions, the highest was 2025 (14,581 t) and the lowest 2023 (4,517 t). Its efficiency percentile within the type went from 31 in 2023 to 38 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 110 of 292 qualifying gas carriers by EEOI, at the 38th percentile. The dashed line is the type median, 27.9; this vessel reported 21.8.

0255075100more efficientless efficientThis vessel: 38th percentile, EEOI 21.8

EEOI divides emissions by transport work, which for this vessel and year was 668,836,697 tonne-miles over 55,882 nautical miles.

2023: 4,517 t20234,5172024: 13,045 t20242025: 14,581 t202514,581

Reported CO₂ in 2025 was 222.8% higher than in 2023, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 11.8% while distance sailed rose 21.4%and CO₂ per nautical mile fell 7.9%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 3 MRV reporting years, an efficiency ranking, 2 of 5 vessel particulars and AIS movements in Norwegian waters. Not found in the sources for this vessel: a name history, a licensed photograph, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
