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 June 2026, Czechia's jet fuel supply was 42 kt: 62% from its own refineries, with imports mainly from Germany (29%) and Slovakia (7%); tracing one step back, the crude behind it is estimated to come mainly from Saudi Arabia (23%), Azerbaijan (19%) and Kazakhstan (16%), and 5% cannot be traced.

Left: the crude oil behind the fuel (an estimate). Middle: the countries whose refineries made it. Right: Czechia’s supply of jet fuel in 2026-06, in tonnes of fuel. Only the middle-to-right flows are reported figures.

Month: 2026-06 (latest month all EU member states reported). Crude mixes are pooled over 2026-04 to 2026-06.

Fuel that cannot be traced, and the reason

  • Czechia: crude not from imports (1,427 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 not from imports (348 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 (167 t): The supplying country's statistics did not say where part of its crude came from.
  • 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.
