Fuel Origin

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 April 2026, Slovakia's jet fuel supply was 15 kt: 92% from its own refineries, with imports mainly from Germany (8%); tracing one step back, the crude behind it is estimated to come mainly from the Russia (20%), the United Kingdom (16%) and Saudi Arabia (16%), and 15% cannot be traced.

One flow with a share under 0.1% is not listed here. It is still counted in every total and drawn in the diagram, and the CSV under Source & method lists every flow.

Left: the crude oil behind the fuel (an estimate). Middle: the country’s own refineries and the countries the fuel was last shipped from, which may be a trading hub rather than where it was refined; the estimate treats each as the refiner. Right: Slovakia’s supply of jet fuel in 2026-04, in tonnes of fuel. Only the middle-to-right flows are reported figures.

Month: 2026-04 (requested). Crude mixes are pooled over 2026-02 to 2026-04.

Fuel that cannot be traced, and the reason

  • Slovakia: crude origin not reported (2,121 t): The supplying country's statistics did not say where part of its crude came from.
  • Smaller flows: crude not from imports (188 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.
  • 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. Imports are counted under the country the fuel was last shipped from; where that country has refineries, fuel that only passed through it is traced as if it had been refined there.
  • Widths are tonnes of this fuel, not tonnes of crude oil: a refinery makes several products from each tonne of crude.
