ASTRO SANISTRA against its type
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 NORD COLORADO for 2018–2021 and ASTRO SANISTRA for 2024–2025. The reported port of registry changed: Singapore (2018–2019), then HELLERUP (2020–2021), then Majuro (2024–2025).
Its 1,429 t of CO₂ for 2025 is 56% 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 324.6 kg CO₂, 25% above the type median of 260.7 kg. It logged 494 hours at sea against a median of 1,200 hours for its type that year. 9.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2020 (7,764 t) and the lowest 2025 (1,429 t). Its efficiency percentile within the type went from 13 in 2018 to 52 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,695 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.
EEOI divides emissions by transport work, which for this vessel and year was 184,880,983 tonne-miles over 4,402 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 73.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 37.7% while distance sailed fell 48.5%and CO₂ per nautical mile rose 20.8%.That points mainly to how much the vessel sailed, rather than the other.
