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 May 2026, Belgium's road diesel supply was 1,285 kt: 60% from its own refineries, with imports mainly from the Netherlands (34%); tracing one step back, the crude behind it is estimated to come mainly from Norway (29%), the United States (17%) and Kazakhstan (11%), and 8% 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: Belgium’s supply of road diesel in 2026-05, in tonnes of fuel. Only the middle-to-right flows are reported figures.
Dashed crude links rest partly on crude imports estimated from published euro values: a supplier did not publish its crude imports for some months of the window (docs/METHODOLOGY.md section 6.1). Customs basis, INFERRED. Method
Month: 2026-05 (requested). Crude mixes are pooled over 2026-03 to 2026-05.
Fuel that cannot be traced, and the reason
- Singapore: no crude data (40,300 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Netherlands: crude origin not reported (30,391 t): The supplying country's statistics did not say where part of its crude came from.
- Smaller flows: no crude data (20,500 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Smaller flows: crude origin not reported (5,629 t): The supplying country's statistics did not say where part of its crude came from.
- Smaller flows: crude not from imports (370 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.
