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 March 2026, Ireland's road diesel supply was 297 kt: 20% from its own refineries, with imports from the Netherlands (38%), the United Kingdom (33%) and Belgium (9%); tracing one step back, the crude behind it is estimated to come mainly from the United States (26%), Norway (12%) and Nigeria (6%), and 36% 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: Ireland’s supply of road diesel in 2026-03, in tonnes of fuel. Only the middle-to-right flows are reported figures.
Month: 2026-03 (requested). Crude mixes are pooled over 2026-01 to 2026-03.
Fuel that cannot be traced, and the reason
- United Kingdom: no crude data (97,991 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 (8,354 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.
