On October 1, 2026, French farmers from the Coordination Rurale union staged a dramatic protest outside the Centre des Finances Publiques in Guyancourt. They dumped agricultural waste and sprayed the building's façade to demand a cap on agricultural fuel prices. The union is calling for the price of non-road diesel (GNR) to be capped at €1 per liter because fuel costs have nearly doubled over the past year, threatening the economic stability of many farms.
