MAREX EXPRESS against its type
Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,289 gross tonnage it is larger than 71% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it MAREX EXPRESS for 2018 and PYXIS KARTERIA for 2022–2025. The reported port of registry changed: SINGAPORE (2018), then Majuro (2022–2025).
Its 3,205 t of CO₂ for 2025 is 42% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 282.9 kg CO₂, 13% above the type median of 250.2 kg. It logged 895 hours at sea against a median of 2,106 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2022 (8,429 t) and the lowest 2025 (3,205 t). Its efficiency percentile within the type went from 54 in 2018 to 6 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 80 of 1,348 qualifying chemical tankers by EEOI, at the 6th percentile. The dashed line is the type median, 14.4; this vessel reported 7.4.
EEOI divides emissions by transport work, which for this vessel and year was 433,657,646 tonne-miles over 11,329 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, so the series has gaps.
From 2023 to 2025, emissions fell 21.9% while distance sailed fell 8.4%and CO₂ per nautical mile fell 14.8%.That points mainly to how efficiently it sailed, rather than the other.
