DSI PYXIS against its type

Built in 2018, it is 6 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 34,547 gross tonnage it is smaller than 53% 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. Its MRV returns name it STH MONTREAL for 2019–2020 and DSI PYXIS for 2023–2025. The reported port of registry changed: Limassol (2019), then Majuro (2020–2025).

Its 2,902 t of CO₂ for 2025 is 10% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 238.0 kg CO₂, close to the type median of 260.7 kg. It logged 1,072 hours at sea against a median of 1,200 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2020 (7,373 t) and the lowest 2019 (1,115 t). Its efficiency percentile within the type went from 16 in 2020 to 52 in 2025 (lower is more efficient). Of the 4 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 1,699 of 3,241 qualifying bulk carriers by EEOI, at the 52nd percentile. The dashed line is the type median, 7.6; this vessel reported 7.7.

Reported CO₂ in 2025 was 160.2% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2024, so the series has gaps.

From 2023 to 2025, emissions fell 18.1% while distance sailed fell 18.7%and CO₂ per nautical mile rose 0.7%.That points mainly to how much the vessel sailed, rather than the other.
