ECO BEL AIR against its type

Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,817 gross tonnage it is larger than 78% 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. Its MRV returns name it ECO BEL AIR for 2019–2023 and P. BEL AIR for 2025. The reported port of registry changed: Majuro (2019–2023), then MADEIRA (2025).

Its 17,995 t of CO₂ for 2025 is 2.3 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 467.9 kg CO₂, 16% above the type median of 403.2 kg. It logged 3,152 hours at sea against a median of 2,030 hours for its type that year. 9.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2025 (17,995 t) and the lowest 2021 (1,960 t). Its efficiency percentile within the type went from 40 in 2019 to 51 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 745 of 1,448 qualifying oil tankers by EEOI, at the 51st percentile. The dashed line is the type median, 7.5; this vessel reported 7.6.

EEOI divides emissions by transport work, which for this vessel and year was 2,377,163,804 tonne-miles over 38,457 nautical miles.

Reported CO₂ by year

2019: 15,993 t201915,9932020: 13,142 t20202021: 1,960 t20212022: 3,920 t20222023: 11,195 t20232025: 17,995 t202517,995

Reported CO₂ in 2025 was 12.5% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions rose 60.7% while distance sailed rose 41.9%and CO₂ per nautical mile rose 13.3%.That points mainly to how much the vessel sailed, rather than the other.
