PUNA against its type
Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 20,535 gross tonnage it is smaller than 90% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 212 bulk carriers here under the Cyprus flag, 2.6% of the 8,138 on the register. Its MRV returns name it THREE RIVERS for 2018–2019 and PUNA for 2020–2025. The reported port of registry changed: St. Johns (2018), then Monrovia (2019–2023), then Limassol (2024–2025).
Its 3,148 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 207.2 kg CO₂, 21% below the type median of 260.7 kg. It logged 1,638 hours at sea against a median of 1,200 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2018 (5,588 t) and the lowest 2021 (2,771 t). Its efficiency percentile within the type went from 93 in 2018 to 96 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 3,121 of 3,241 qualifying bulk carriers by EEOI, at the 96th percentile. The dashed line is the type median, 7.6; this vessel reported 16.6.
EEOI divides emissions by transport work, which for this vessel and year was 189,098,498 tonne-miles over 15,192 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 43.7% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 18.1% while distance sailed fell 3.4%and CO₂ per nautical mile fell 15.2%.That points mainly to how efficiently it sailed, rather than the other.
