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, Austria's road diesel supply was 485 kt: 45% from its own refineries, with imports mainly from Germany (43%) and Slovenia (7%); tracing one step back, the crude behind it is estimated to come mainly from Kazakhstan (35%), the United States (16%) and Libya (10%), and 10% 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 countries whose refineries made it. Right: Austria’s supply of road diesel 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
- Slovenia: no refinery (33,505 t): The supplying country has no crude oil refinery (a cited confirmed zero), so the fuel was made elsewhere and passed through. We look back one step only.
- Austria: crude not from imports (8,574 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.
- Germany: crude not from imports (5,233 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 (1,314 t): The supplying country's statistics did not say where part of its crude came from.
- Smaller flows: crude not from imports (734 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; 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.
