VALLE AZZURRA: CO₂ emissions 2018–2025

IMO 9391488 EU ETS7 reporting years

CO₂ reported 2024: 2,145 t
Fuel burned: 675 t
Distance: 7,368 nm
Time at sea: 702 h
Emitted at berth: 11% of total
Share of year under way: 8%
Gross tonnage: 29,987

No EU/EEA voyages were reported for 2025. The return shows zero CO₂ and zero time at sea, which means the vessel did not sail to, from or between EEA ports that year. It is not a cut in emissions, and that year is left out of the trend and of any ranking.

Efficiency against its own type2024

Position 1,039 of 1,566 qualifying oil tankers by EEOI, at the 66th percentile. The dashed line is the type median, 7.6; this vessel reported 9.1.

EEOI divides emissions by transport work, which for this vessel and year was 236,489,526 tonne-miles over 7,368 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2024 was 12.7% lower than in 2018. EU MRV only covers voyages to, from and within the EU/EEA, so a change can reflect where the vessel sailed as much as how much it emitted. No return is recorded for 2021, so the series has gaps.

From 2023 to 2024, emissions fell 83.6% while distance sailed fell 82.8%and CO₂ per nautical mile fell 4.8%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2024 emissions occurred

Methane, nitrous oxide and EU ETS2024

Total CO₂ equivalent: 2,178 t
Methane (CH₄): 0.03 t
Nitrous oxide (N₂O): 0.12 t
Under EU ETS: 1,321 t, 62% of total

Caveats that apply to every vessel page

EEOI above 100,000 is withheld. Those values come from returns where reported transport work is near zero, which makes the ratio meaningless rather than extreme. Median across the dataset is around 12.

Emission categories overlap. In the MRV return, emissions at berth are also counted inside the voyage legs, so the categories do not sum to the total. They are shown side by side rather than stacked for that reason.

Distance is derived, intensity is reported. The MRV return publishes CO₂ per nautical mile but not the distance itself, which is null in all 106,564 rows of the source. The distance column is therefore filled from the ranking step, which reconstructs it, and is blank for years where a vessel was not ranked. That is why a row can show an intensity without a distance.

Percentile is within type and year. It is the vessel's position among qualifying ships of the same type that year, where lower is more efficient. A blank means the vessel did not qualify for ranking that year.

Sister ships share a builder, a type and a build year within two years of this vessel. That holds hull and machinery roughly constant and leaves operation as the variable, which is why they are listed before nearest-by-tonnage.

Methane and nitrous oxide start in 2024. They were not reported before that period, so earlier years cannot be compared against them.

Technical efficiency is a design figure fixed at construction. A vessel can hold a good index and still emit heavily by sailing fast, waiting at anchor or carrying little.

Inspection records cover United States waters only. An empty record is not evidence of a clean history elsewhere.

Empty means unreported, never zero. Nothing here is modelled, estimated or interpolated. See the methodology.
