Puissance Verte, a new political movement focused on environmental issues, was officially launched in early October by Florence Portelli, the mayor of Taverny and a member of Les Républicains, and Ferréol Delmas, the general director of the think tank Écologie responsable. The movement seeks to integrate environmental concerns into the policies of center and right-wing parties to better align with the expectations of voters. On Sunday, October 4, Portelli and Delmas gathered elected officials, former politicians, and experts in Amboise (Indre-et-Loire) to unveil their project. The initiative was inspired by the increasing number of wildfires and heatwaves this summer, with Portelli arguing that the right must take environmental issues more seriously. As vice-president of the AMF and deputy president of the Île-de-France region, she emphasized that many local officials on the right already practice ecology at the municipal and regional levels. Basile Imbert, a political science doctoral student at the University of Montpellier and an elected member of the Socialist Party, attended the launch as an observer. He noted that in recent years, right-wing parties have attempted to rebrand their approach to ecology and reclaim influence on the issue. Imbert explained that while these parties have always had positions on environmental matters, they have often been ambivalent. He cited Nicolas Sarkozy, who both launched the Grenelle de l'environnement in 2008 and later commented that "environmentalism has started to get old." Imbert acknowledged that Puissance Verte appears to represent a new trend, with several right-wing movements present at the launch, including Les Républicains, Jean-Louis Borloo, and Horizons. He noted that the movement seems more ambitious than previous attempts, creating a space to generate ideas in the absence of a clear reference for right-wing ecology. Portelli emphasized that Puissance Verte aims to bring the expectations and challenges faced by local elected officials to the attention of center and right-wing parties at the national level. She criticized the neglect of environmental issues in national politics and argued that many elected officials, regardless of their political affiliation, practice ecology out of common sense, such as recycling to save money. The movement's novelty lies in its open embrace of ecology, with Portelli stating, "we are right-wing, we are ecological, and if that doesn't please you, too bad." She criticized Les Ecologistes for promoting "an extremely punitive ecology" and advocated for the center and right to adopt a more encouraging approach to environmental policies. Portelli argued that ecology should not be the exclusive domain of the left and highlighted the right's approach to growth as "not growth at all costs, but a healthier growth." She pointed to the overconsumption of imported products due to the country's deindustrialization and emphasized the benefits of producing domestically to avoid reliance on imports. While supporting nuclear energy, which she described as a source of pride for the right, she criticized the opposition to renewable energies. She lamented the focus on wind turbines, arguing that other forms of renewable energy, such as solar, hydro, and geothermal, should also be considered. Imbert noted that right-wing ecology without nuclear energy is difficult to imagine, given the historical support for it by figures like De Gaulle, Pompidou, and Messmer. Puissance Verte aims to reflect the ecological expectations of right-wing voters, who support expanding renewable energy production. More than 74% of Les Républicains voters want to double the renewable energy capacity from wind and solar power by 2030. However, this support is not reflected in the decisions of their representatives in the National Assembly, as right-wing deputies voted for a moratorium on new electricity production installations using photovoltaic and wind energy in June 2025. Bruno Retailleau, the presidential candidate of Les Républicains, declared in May that he wanted to "get out of the trap of the ecological ideology" and "stop public funding for wind and photovoltaic energies." As a political movement rather than a party, Puissance Verte aims to influence the upcoming presidential campaign by ensuring that environmental issues are addressed in the programs of the right and the center. However, Imbert cautioned that right-wing representatives have a history of opposing ecological policies, such as Laurent Wauquiez's opposition to the ZAN law (Zero net artificialization) or Bruno Retailleau's Senate campaign in favor of the Duplomb law. While the movement is currently in a mobilization phase, its long-term impact remains uncertain.
