A new citizen assembly called "Un Commun accord" is set to begin its first meetings in Paris on 19 and 20 September. The initiative, launched by nuclear engineer and environmental thinker Jean-Marc Jancovici, is led by Audrey Cerdan, the climate editor-in-chief of France Télévisions. The assembly is non-partisan and aims to contribute to the upcoming 2027 presidential election debate in a unique way. Over six weekends, 150 citizens selected by lottery—representative of French society—will meet in Paris to discuss ecological, financial, and social challenges. Participants may later present their proposals directly to presidential candidates. The project is funded through a crowdfunding campaign that, by 17 September, had attracted over 175,000 contributors aiming to raise 1 million euros. An additional 2 million euros has been secured from individual donors who signed a "Financiers Charter" pledging not to influence the assembly’s direction. The total budget of 3 million euros will cover venue costs, session facilitation, and travel and accommodation expenses for participants. The assembly will include input from scientists and experts, such as paleoclimatologist Valérie Masson-Delmotte, and a public platform will allow broader participation. This initiative is similar to the 2019-2020 Citizen Climate Convention (CCC), which generated proposals later included in a 2021 climate law. However, only 16% of the CCC’s recommendations have been implemented so far. While some NGOs and former CCC members view "Un Commun accord" as a promising step toward consensus on environmental solutions, others question its potential impact and whether it will differ significantly from the earlier effort. Concerns have been raised about the lack of formal guarantees that presidential candidates will act on the assembly’s proposals and about potential bias due to the Shift Project’s administrative involvement, which has faced criticism for its ties to pro-nuclear groups. The assembly will also explore practical dilemmas, such as whether to favor cheaper imported cars or more expensive French cars to support jobs. However, some experts warn that such choices might shift responsibility to individuals rather than the collective, making it harder to translate citizen input into political action. Despite these challenges, the initiative is expected to raise awareness and engage political leaders on environmental issues. With the involvement of high-profile figures like Jancovici, the assembly is anticipated to receive significant media attention and could influence the 2027 presidential campaign.
