Source and method
The national average prices come from Weekly Oil Bulletin (European Commission, Directorate-General for Energy (DG ENER)). We import the published values once a week; we do not recompute them from station-level data. For each reference week, we use the national average for diesel reported in the publication Weekly Oil Bulletin. We compare consecutive weekly observations without reconstructing a station sample. Full method: how we calculate.
This article reports only what the national values published in the Weekly Oil Bulletin show. It does not attribute the change to any cause.
