The Council of State, France’s highest administrative court, has ordered the government to implement a ban on advertising for fossil fuels. The decision, announced on October 2, requires Prime Minister Sébastien Lecornu to publish a decree within six months that will allow the ban to take effect. This measure was originally included in the Climate and Resilience Act, passed in 2021, which aims to reduce the environmental impact of fossil fuel use in France. The law targets advertising for oil, natural gas, coal, and other related energy sources, as well as heat generated primarily from these fuels. However, the ban has not yet been put into practice. The government had delayed publishing the decree, arguing that the law was too vague and could conflict with freedom of expression and property rights. The Council of State rejected these concerns, ruling in favor of the association Resistance to Advertising Aggression (RAP). RAP has been advocating for the ban for several years, aiming to limit the promotion of fossil fuels and their associated products. The court’s decision marks a significant legal victory for the group, though it does not fully achieve its goals. The association welcomed the ruling as a positive step, but it noted that the current law only prohibits advertising for fossil fuels themselves, not the goods and services linked to them. For example, advertising for gasoline-powered cars or cruise ships, which rely on fossil fuels, is not covered by the ban. This limitation has been a point of criticism for environmental activists, who argue that a more comprehensive approach is needed to effectively reduce fossil fuel consumption. The implementation of the ban now depends on the government’s ability to draft and publish the required decree within the given timeframe. If enacted, the measure could significantly impact how fossil fuel-related industries market their products in France. However, the delay in implementation highlights the ongoing challenges in translating legislative goals into practical policy.
