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 2025, Slovenia's road diesel supply was 210 kt, all of it imported, mainly from Greece (36%), Italy (32%) and Türkiye (17%); tracing one step back, the crude behind it is estimated to come mainly from Kazakhstan (15%), Iraq (14%) and Libya (12%), and 35% 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: Slovenia’s supply of road diesel in 2025-07, in tonnes of fuel. Only the middle-to-right flows are reported figures.
Month: 2025-07 (requested). Crude mixes are pooled over 2025-05 to 2025-07.
Fuel that cannot be traced, and the reason
- Türkiye: no crude data (35,000 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 (31,000 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Italy: crude not from imports (7,064 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 (179 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.
