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 December 2025, Denmark's road diesel supply was 72 kt: 92% from its own refineries, with imports from Norway (8%); tracing one step back, the crude behind it is estimated to come mainly from Norway (36%) and the United States (30%), and 34% cannot be traced.

One flow with a share under 0.1% is not listed here. It is still counted in every total and drawn in the diagram, and the CSV under Source & method lists every flow.

- 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: Denmark’s supply of road diesel in 2025-12, in tonnes of fuel. Only the middle-to-right flows are reported figures.
Month: 2025-12 (requested). Crude mixes are pooled over 2025-10 to 2025-12.
Fuel that cannot be traced, and the reason
- Denmark: crude not from imports (18,550 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.
- Norway: no crude data (6,000 t): We hold no crude import statistics for the supplying country, and we do not assume what its refineries run on.
- Smaller flows: crude origin not reported (33 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; 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.
