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, Slovenia's road diesel supply was 275 kt, all of it imported, mainly from Saudi Arabia (36%), Egypt (20%) and Italy (20%); tracing one step back, the crude behind it is estimated to come mainly from Libya (6%) and Kazakhstan (6%), and 69% 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: Slovenia’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
- Saudi Arabia: no crude data (98,000 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Egypt: no crude data (56,000 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Türkiye: no crude data (34,000 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Smaller flows: crude not from imports (1,915 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.
