PS MILANO against its type
It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. Its MRV returns name it THAMES for 2018–2021, PS MILANO for 2023–2024 and CAPTAIN NIKOS for 2025. The reported port of registry changed: Monrovia (2018–2021), then Genova (2023–2024), then Majuro (2025).
Its 10,316 t of CO₂ for 2025 is 1.9 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 271.5 kg CO₂, close to the type median of 250.2 kg. It logged 4,160 hours at sea against a median of 2,106 hours for its type that year. 5.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2025 (10,316 t) and the lowest 2021 (1,760 t). Its efficiency percentile within the type went from 9 in 2018 to 37 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 496 of 1,348 qualifying chemical tankers by EEOI, at the 37th percentile. The dashed line is the type median, 14.4; this vessel reported 12.1.
EEOI divides emissions by transport work, which for this vessel and year was 849,737,232 tonne-miles over 38,000 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 67.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 194.6% while distance sailed rose 166.2%and CO₂ per nautical mile rose 10.7%.That points mainly to how much the vessel sailed, rather than the other.
