ITHACA RIGA against its type

Built in 2010, it is 3 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 22,409 gross tonnage it is larger than 85% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Its MRV returns name it ITHACA RIGA for 2018 and SHAMAN WISDOM for 2021–2025. The returns for 2021–2025 all give MAJURO as port of registry.

Its 5,050 t of CO₂ for 2025 is 1.8 times 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 225.8 kg CO₂, 1.8 times the type median of 122.2 kg. It logged 2,105 hours at sea against a median of 3,044 hours for its type that year. 1.0% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2025 (5,050 t) and the lowest 2021 (1,618 t). Its efficiency percentile within the type went from 91 in 2021 to 2 in 2025 (lower is more efficient). Of the 4 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 11 of 479 qualifying general cargo ships by EEOI, at the 2nd percentile. The dashed line is the type median, 29.4; this vessel reported 8.9.

Reported CO₂ in 2025 was 212.1% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.

From 2023 to 2025, emissions rose 67.6% while distance sailed rose 73.9%and CO₂ per nautical mile fell 3.6%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 6 MRV reporting years, an efficiency ranking, 4 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.
