Flows

How oil reaches each country

Where the EU’s crude oil and fuel come from, as each member state reports its imports; every band’s width is proportional to tonnes.

In March 2024, Portugal's road diesel supply was 379 kt: 80% from its own refineries, with imports mainly from Spain (20%); tracing one step back, the crude behind it is estimated to come mainly from Brazil (31%), Algeria (20%) and Nigeria (17%), and 2% cannot be traced.

Left: the crude oil behind the fuel (an estimate). Middle: the countries whose refineries made it. Right: Portugal’s supply of road diesel in 2024-03, in tonnes of fuel. Only the middle-to-right flows are reported figures.

Month: 2024-03 (requested). Crude mixes are pooled over 2024-01 to 2024-03.

Fuel that cannot be traced, and the reason

  • Portugal: crude not from imports (5,452 t): The refineries used more crude than the country imported (its own production or stocks). That part is not traced rather than being filled with the import mix.
  • Smaller flows: crude origin not reported (1,313 t): The supplying country's statistics did not say where part of its crude came from.
  • Smaller flows: crude not from imports (618 t): The refineries used more crude than the country imported (its own production or stocks). That part is not traced rather than being filled with the import mix.
  • Smaller flows: no crude data (14 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
  • Only the supplier -> country links are reported figures. The crude -> supplier links are an estimate: each supplier's fuel is split by that supplier's own crude-import mix over the latest three months.
  • Exports are assumed to be drawn from every source in proportion to its share of supply.
  • The chain looks back one country only; fuel re-exported through a supplier is not followed further.
  • Widths are tonnes of this fuel, not tonnes of crude oil: a refinery makes several products from each tonne of crude.
