Gasoline and diesel prices in France are continuing to rise, with notable differences between regions. As of September 22, 2026, the average price per liter of fuel at the pump was 2.445 euros in the Bourgogne-Franche-Comté region, while in Corsica it was 2.304 euros. The highest average prices were recorded in Bourgogne-Franche-Comté, Grand-Est, and Auvergne-Rhône-Alpes, while the lowest prices were found in Corsica, Brittany, and Nouvelle-Aquitaine. These variations are due to a combination of factors, including the size of gas stations, their business models, and the methods used to transport fuel. Blandine Ruty, general secretary of the Union française des industries pétrolières (UFIP), explained that the differences in fuel prices are "multifactorial." Since a 1985 decree, fuel prices at gas stations have been free to set based on market conditions. This means that each station can adjust its prices independently. For example, a smaller, rural station that is restocked less frequently or a motorway station with no nearby competition tends to have higher prices compared to larger stores with more competition. In Brittany, the presence of many large and medium-sized stores has increased competition, helping to keep prices slightly lower. Transportation methods also have a significant impact on fuel prices. Transporting fuel via pipeline is generally the cheapest option, followed by ships, and then by trucks. This summer, the Rhine River’s water levels dropped, forcing a reevaluation of how oil is delivered to stations in the Grand-Est region. Lower water levels mean barges can carry less cargo, requiring more trips or switching to land routes, which are more expensive. This led to some gas stations in Alsace running out of gasoline, a problem that continues. In Brittany, the lack of highways and tolls makes fuel transportation more cost-effective. Corsica has its own unique delivery system due to its status as an island, which makes its fuel pricing situation somewhat different from the rest of France. These regional variations highlight how multiple factors—ranging from local market competition to transportation logistics—contribute to the fluctuating prices at gas stations across the country.
