EMERALD ACE against its type

Built in 2012, it is 4 years newer than the median vehicle carrier on this register, which was built in 2008 (595 vessels with a known build year). At 60,154 gross tonnage it is larger than 65% of the other 571 vehicle carriers with a recorded tonnage. It is one of 62 vehicle carriers here under the Marshall Islands flag, 8.7% of the 713 on the register. The same builder is recorded for 25 other vessels here, 3 of them vehicle carriers. The returns for 2018–2025 all give MAJURO as port of registry.

Its 5,342 t of CO₂ for 2025 is 24% below the median of 7,074 t among the 514 vehicle carriers on this register that reported for 2025. Per nautical mile it emitted 302.3 kg CO₂, close to the type median of 309.1 kg. It logged 1,084 hours at sea against a median of 1,639 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for vehicle carriers was 3.1%. Across 8 years with reported emissions, the highest was 2023 (9,735 t) and the lowest 2019 (1,196 t). Its efficiency percentile within the type went from 53 in 2018 to 84 in 2023 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ in 2025 was 33.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 6.1% and CO₂ per nautical mile rose 0.7%.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

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