SAPPHIRA against its type
Built in 2008, it is 2 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 79,235 gross tonnage it is larger than 70% of the other 2,841 oil tankers with a recorded tonnage. It is one of 56 oil tankers here under the Portugal flag, 1.6% of the 3,548 on the register. The reported port of registry changed: Antwerp (2019–2023), then Madeira (2024–2025).
Its 7,780 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 523.0 kg CO₂, 30% above the type median of 403.2 kg. It logged 1,414 hours at sea against a median of 2,030 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2020 (19,703 t) and the lowest 2024 (4,294 t). Its efficiency percentile within the type went from 24 in 2019 to 41 in 2025 (lower is more efficient).

Efficiency against its own type2025
Position 600 of 1,448 qualifying oil tankers by EEOI, at the 41st percentile. The dashed line is the type median, 7.5; this vessel reported 6.8.
EEOI divides emissions by transport work, which for this vessel and year was 1,144,101,471 tonne-miles over 14,875 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 21.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 81.2% while distance sailed rose 54.7%and CO₂ per nautical mile rose 17.1%.That points mainly to how much the vessel sailed, rather than the other.
