Energie et climat : ceux qui phosphorent autour de Jean-Luc Mélenchon

Jean-Luc Mélenchon has clearly stated in his closing speech at the Amfis, the summer university of the Insoumis, at the end of August, that ecological planning will be a strong axis of his presidential election candidacy. Several working groups are working on updating the candidate's program, coordinated by deputies Clémence Guetté and Hadrien Clouet. This program is expected to be presented by the end of 2026. Politico presents the working groups related to energy and climate questions.

The core of the ecological planning booklet "should not change much from 2022," according to deputy Anne Stambach-Terrenoir, who is very invested in this topic. The novelty of the presidential program is the concept of ecoregions, an administrative reorganization around natural boundaries, which is the subject of a dedicated working group.

It is led by Delphine Ducret, a leader of an environmental NGO, and Michel Philippo, who works on ecological construction. The movement also includes the Popular Greens, bringing together Ecologists who joined La France insoumise in 2025, particularly through a note dedicated to fighting against fires. In relation to these topics, Anne Stambach-Terrenoir builds a network of ecological struggles to connect activists and collectives opposing large projects and the party's elected officials.

She also plans a "tour of struggles" in the fall. The parliamentary associates are Claire Lejeune and Anne Stambach-Terrenoir.

On energy, "the programmatic foundation is clear" on energy with "invariants" since 2017, or even 2012, explains engineer Jean-Baptiste Grenier, member of the La Boétie Institute, the party's idea box. Namely: a planning towards a 100% renewable energy mix, based on sobriety as well as the exit of nuclear power, and organized around a public energy pole and regulated tariffs.

The working group, passing from about 50 to 110 members in a few months, is led by anti-nuclear and anti-Cigéo activist Angélique Huguin, physicist Jean-Marie Brom, and Bourges resident Quentin Briegel. They have conducted several hearings in June with environmental NGOs and trade unions to update the booklet. La Boétie Institute, particularly engineer Jean-Baptiste Grenier (who coordinated a note on the subject last year), also nurtures the reflection.

The parliamentary associates are Maxime Laisney, Alma Dufour, and Marina Mesure. Deputy Matthias Tavel, invested in the working group on the sea, has also contributed to the work on offshore wind energy, in particular.

The installation of ecoregions is one of the novelties of Jean-Luc Mélenchon's program. Drawn from basins of catchment areas - because "at the end of the day, it all comes down to water" - these new administrative regions will be leaders in ecological planning on the territory. "They will be their first line of alert, their first line of implementation, their first line of proposals," said Mélenchon candidate for La France insoumise at the beginning of July, explaining that these regions will have to ensure the quality of water, land, air, and forests, as well as issues of mobility and health.

The ecoregions were presented in a column published the same day, signed by Insoumis parliamentary representatives, activists, and members of the Popular Greens. The parliamentary associates are Gabriel Amard and Claire Lejeune. But also... A working group on housing is led by the director of the school of training of La Boétie Institute, Antoine Salles-Papou, and Cassandre Bliot, a parliamentary collaborator.

Deputy François Piquemal is also engaged on these topics. Deputée Aurélie Trouvé federates a network of small and medium-sized enterprise heads close to the Insoumis, including several from energy or industrial sectors. She is also working in tandem with Finance Committee President Eric Coquerel on the wording of Mélenchon's program.

Finally, she is working on a dozen productive investment plans that will draw, for each sector concerned (energy, building, steel, chemistry, automotive...), "an ecological and social relaunch of production," she says. Klara Durand contributed to this article.
