SERENITY: CO₂ emissions 2019–2025

SERENITY against its type

Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 30,092 gross tonnage it is smaller than 71% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 54 other vessels here, 4 of them bulk carriers. Its MRV returns name it VALOVINE for 2019–2023 and SERENITY for 2025. The reported port of registry changed: Pula (2019–2021), then Majuro (2023–2025).

Its 5,141 t of CO₂ for 2025 is 1.6 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 348.1 kg CO₂, 33% above the type median of 260.7 kg. It logged 1,364 hours at sea against a median of 1,200 hours for its type that year. 4.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2025 (5,141 t) and the lowest 2023 (2,127 t). Its efficiency percentile within the type went from 70 in 2019 to 66 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,132 of 3,241 qualifying bulk carriers by EEOI, at the 66th percentile. The dashed line is the type median, 7.6; this vessel reported 8.8.

EEOI divides emissions by transport work, which for this vessel and year was 587,596,571 tonne-miles over 14,772 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 37.7% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2024, so the series has gaps.

From 2023 to 2025, emissions rose 141.7% while distance sailed rose 88.2%and CO₂ per nautical mile rose 28.5%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

• Emissions: EU MRV publication (THETIS-MRV), reporting years 2019–2025, published by the European Commission.
• Vessel particulars: Wikidata (CC0).

This page draws on 5 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.
