CPO SWEDEN against its type

Built in 2008, it is 2 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,353 gross tonnage it is larger than 53% 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 CPO SWEDEN for 2018, RIDGEBURY ELVIA B for 2019 and DALE for 2020–2025. The reported port of registry changed: London (2018), then Majuro (2019–2025).

Its 8,172 t of CO₂ for 2025 is 48% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 289.3 kg CO₂, 16% above the type median of 250.2 kg. It logged 2,935 hours at sea against a median of 2,106 hours for its type that year. 15.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (14,526 t) and the lowest 2023 (5,695 t). Its efficiency percentile within the type went from 44 in 2018 to 76 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,024 of 1,348 qualifying chemical tankers by EEOI, at the 76th percentile. The dashed line is the type median, 14.4; this vessel reported 23.8.

EEOI divides emissions by transport work, which for this vessel and year was 343,635,828 tonne-miles over 28,249 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 39.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 33.6% while distance sailed rose 36.9%and CO₂ per nautical mile fell 2.4%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 8,298 t
Methane (CH₄): 0.13 t
Nitrous oxide (N₂O): 0.46 t
Under EU ETS: 5,800 t, 71% of total
