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 July 2026, Bulgaria's jet fuel supply was 17 kt: 82% from its own refineries, with imports mainly from Romania (16%); tracing one step back, the crude behind it is estimated to come mainly from Kazakhstan (7%), and 87% cannot be traced.

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: Bulgaria’s supply of jet fuel in 2026-07, in tonnes of fuel. Only the middle-to-right flows are reported figures.

Month: 2026-07 (latest month that can be drawn, the month its country page shows). Crude mixes are pooled over 2026-05 to 2026-07.

Fuel that cannot be traced, and the reason

  • Bulgaria: crude origin not reported (14,019 t): The supplying country's statistics did not say where part of its crude came from.
  • Romania: crude not from imports (703 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 (37 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.
