SIGAIA THERESA against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 7,280 gross tonnage it is smaller than 90% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 95 chemical tankers here under the Norway flag, 4.1% of the 2,344 on the register. The returns for 2021–2025 all give Oslo as port of registry.
Its 5,689 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 147.3 kg CO₂, 41% below the type median of 250.2 kg. It logged 3,704 hours at sea against a median of 2,109 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2022 (6,840 t) and the lowest 2023 (3,315 t). Its efficiency percentile within the type went from 69 in 2021 to 84 in 2025 (lower is more efficient). Of the 8 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 1,133 of 1,348 qualifying chemical tankers by EEOI, at the 84th percentile. The dashed line is the type median, 14.4; this vessel reported 29.8.
EEOI divides emissions by transport work, which for this vessel and year was 190,724,438 tonne-miles over 38,621 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.3% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 6.4% while distance sailed fell 6.8%and CO₂ per nautical mile rose 0.4%.That points mainly to how much the vessel sailed, rather than the other.
