ROBERTA against its type
Built in 2003, it is 7 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 22,184 gross tonnage it is smaller than 91% of the other 2,841 oil tankers with a recorded tonnage. It is one of 72 oil tankers here under the Denmark flag, 2.0% of the 3,548 on the register. The same builder is recorded for 192 other vessels here, 71 of them oil tankers. The returns for 2018–2023 all give Roemoe as port of registry.
Its 1,106 t of CO₂ for 2023 is 85% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 318.6 kg CO₂, 22% below the type median of 408.5 kg. It logged 316 hours at sea against a median of 1,807 hours for its type that year. 4.8% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 3 years with reported emissions, the highest was 2018 (8,565 t) and the lowest 2023 (1,106 t). Of the 3 sister ships listed below with a 2023 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2023 was 87.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2022, so the series has gaps.
From 2021 to 2023, emissions fell 60.2% and CO₂ per nautical mile rose 42.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
