A petition in France calling for mandatory Nutri-Score labeling on food packaging has reached the required 100,000 signatures and is now under review by the commission on social affairs. The petition, titled pour rendre obligatoire l'affichage du Nutri-Score sur les emballages des aliments en France, was submitted in November 2025 by specialists, including French epidemiologist and nutritionist Serge Hercberg. Currently, Nutri-Score labeling is voluntary, and the petition argues this approach is not enough to provide clear and accessible nutritional information to help consumers make healthier choices. The commission on social affairs will consider the petition on October 7, 2026. However, only petitions with 500,000 signatures can be debated in the full parliamentary chamber. The petition has received support from two cross-party amendments to the bill on the financing of the Social Security system (PLFSS). These amendments, signed by deputies from eight parliamentary groups (excluding the National Rally, its ally UDR, and France Insoumise), aim to make Nutri-Score labeling mandatory on food packaging, with exceptions for products with protected designations of origin or geographical indications. Fines would be imposed for non-compliance, with the proceeds going to the National Health Insurance Fund. A second amendment would require Nutri-Score to be displayed on all food advertising materials, with the same exceptions. These amendments are expected to be discussed after Article 8 of the PLFSS, which deals with the introduction of a "sugar tax" modeled on the "soda tax." In 2026, an amendment to make Nutri-Score mandatory was passed in the first reading of the PLFSS but was later rejected in the second. Sandrine Runel, a Socialist deputy and rapporteur for the petition, stated that the amendment failed due to a lack of mobilization during lengthy and turbulent debates, rather than a lack of political will. She has not ruled out reintroducing her legislative proposal in the future if these new amendments are also rejected. Nutri-Score is a labeling system that uses a letter grade from A to U to indicate the nutritional quality of food products, with A being the healthiest and U the least. It was introduced in France in 2020 and has since been used on many packaged foods. The system aims to help consumers quickly assess the healthiness of food products based on factors such as sugar, salt, and fat content. The debate over its mandatory use reflects broader discussions about public health, consumer rights, and the role of government in regulating food choices.
