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 2025, Czechia's petrol supply was 182 kt: 63% from its own refineries, with imports mainly from Germany (23%), Austria (7%) and Slovakia (7%); tracing one step back, the crude behind it is estimated to come mainly from Azerbaijan (30%), Norway (20%) and Kazakhstan (17%), and 2% cannot be traced.

- Supplier -> country links are published figures (OFFICIAL; the unattributed remainder and any 'Other suppliers' sum are CALCULATED).
- Crude -> supplier links are an estimate (INFERRED) from each supplier's crude-import mix; the published crude imports behind each one are in links[].evidence.
- Untraceable volumes are explicit UNKNOWN nodes with their cause. They are never spread over the traced origins.
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: Czechia’s supply of petrol in 2025-06, in tonnes of fuel. Only the middle-to-right flows are reported figures.
Month: 2025-06 (requested). Crude mixes are pooled over 2025-04 to 2025-06.
Fuel that cannot be traced, and the reason
- Germany: crude origin not reported (2,814 t): The supplying country's statistics did not say where part of its crude came from.
- Smaller flows: crude not from imports (1,118 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 (453 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. 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.
