MARMUNA: CO₂ emissions 2018–2025

MARMUNA against its type

Built in 2002, it is 5 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 7,406 gross tonnage it is larger than 57% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 310 general cargo ships here under the Panama flag, 10.1% of the 3,081 on the register. The same builder is recorded for 34 other vessels here, 32 of them general cargo ships. Its MRV returns name it MARMUNA for 2018–2019 and UMS-ALBEDO for 2020–2025. The reported port of registry changed: Saint John's (2018–2019), then PANAMA (2020–2025).

Its 2,269 t of CO₂ for 2025 is 20% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 169.6 kg CO₂, 39% above the type median of 122.2 kg. It logged 2,390 hours at sea against a median of 3,044 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2018 (4,359 t) and the lowest 2022 (537 t). Its efficiency percentile within the type went from 70 in 2020 to 53 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 172 of 321 qualifying general cargo ships by EEOI, at the 53rd percentile. The dashed line is the type median, 23.6; this vessel reported 24.8.

EEOI divides emissions by transport work, which for this vessel and year was 71,713,075 tonne-miles over 13,241 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 48.0% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 27.7% and CO₂ per nautical mile rose 26.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

• Emissions: EU MRV publication (THETIS-MRV), reporting years 2018–2025, published by the European Commission.
• Vessel particulars: Wikidata (CC0).

This page draws on 8 MRV reporting years, an efficiency ranking, 5 of 5 vessel particulars and a name history. Not found in the sources for this vessel: AIS movements in Norwegian waters, 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.
