Cler

What Cler does

Cler (legal name: CLER - Réseau pour la transition énergétique) is a French non-profit association (loi 1901) founded in 1984 and headquartered in Paris (with mailing address in Bâtiment Wikivillage, 8 rue de Srebrenica, 75020 Paris), operating as a national network that coordinates actors working on energy transition in France. The organization runs several branded programs and sub-networks: TEPOS (Territoires à énergie positive) covering 212+ territories committed to positive energy status; RAPPEL, a network of 20+ partner organizations fighting energy poverty in housing; the Rénnovons coalition for building energy efficiency; the Réseau Sobriété with over 150 actors; and the 2025 Alliance pour l'énergie locale federating 12 organizations. Cler serves local authorities and elected officials, member organizations (associations, enterprises, local energy agencies), energy transition professionals, and citizens, delivering services including professional training, publications (notably the quarterly Notre énergie), webseminars, advocacy campaigns, and convening events such as Rencontres TEPOS (with 350+ training participants in 2025 and 90% recommendation rate).

Cler has no proprietary technology product; its core "platform" is the network itself, the methodologies (e.g., TEPOS), and the content library. The organization has a small staff (11-50 employees) and generated no disclosed revenue, but is funded primarily through membership fees, public grants (including from ADEME, Banque des Territoires, and Fondation européenne pour le climat), and project-based revenue from training and events. In 2025, Cler implemented a new organizational structure splitting operations into three complementary entities to reinforce effectiveness, and entered new verticals including sustainable mobility (TIMS program with Mob'in and RARE) and biodiversity-renewable energy dialogue (with WWF France and France Nature Environnement). Commercial and advocacy go-to-market is community-led: growth occurs through member recruitment, training enrollments, coalition expansion, public campaigns, and earned media (nearly 200 press articles in 2025 for the Day Against Energy Poverty).

The customer model is highly distributed across hundreds of dues-paying member organizations, individual practitioners, and local authorities, with no large enterprise anchor customers. European-level engagement (with Transport & Environment, Institut Jacques Delors, CAN Europe) signals an emerging second-tier geographic ambition beyond the French national remit.

Core offering

Cler (CLER - Réseau pour la transition énergétique) is a French non-profit association that operates a national network of member organizations working on energy transition. It delivers training programs for local officials, coordinates coalitions (TEPOS, RAPPEL, Rénovons, Réseau Sobriété, Alliance pour l'énergie locale), publishes resources and a quarterly magazine, organizes national events, and conducts advocacy on renewable energy, energy poverty, building renovation, sobriety, and sustainable mobility.

Product overview

Cler (Réseau pour la transition énergétique) is a non-profit network organization that connects and supports actors involved in energy transition in France. Rather than a unified software product, Cler operates as an association offering programs and initiatives including TEPOS (Territoires à énergie positive), RAPPEL (energy poverty network), the Rénovons coalition for building renovation, training programs, publications, webseminars, and advocacy campaigns. The organization does not develop or sell commercial technology products but rather facilitates knowledge-sharing, coordination, and advocacy among its member organizations.

Broad incumbents

• ADEME: France's national agency for ecological transition, funding and convening environmental and energy programs. Broader incumbent with public-sector authority and substantially larger budget, overlapping Cler's advisory and advocacy remit.
• France Nature Environnement: Largest French federation of environmental associations. Comparable membership-network model and national coordination role, but with a broader environmental remit that encompasses biodiversity, which Cler touches via renewables/biodiversity partnerships.
• Fondation pour la Nature et l'Homme: Major French environmental foundation operating across climate, energy, and biodiversity. Comparable advocacy and convening function, broader portfolio, and substantially larger funding base than Cler.
• WWF France: French arm of the global environmental NGO, active in climate advocacy and renewable-energy deployment. A strategic 2025 partner of Cler in biodiversity/renewables dialogues; comparable advocacy footprint with broader scope and larger institutional resources.

Emerging players

• Enercoop: French renewable-energy cooperative and Cler network member. Adjacent rather than directly overlapping — a commercial cooperative rather than a network — but highly comparable because both operate at the intersection of renewable energy, citizen participation, and cooperative governance.

Direct peers

• GERES: French non-profit working on energy access, renewable energy, and solidarity-driven climate action. Comparable non-profit structure and energy/poverty focus, with the Slime program directly overlapping Cler's RAPPEL on energy poverty.
• Association négaWatt: French non-profit think tank developing the eponymous energy-transition scenario based on sobriety, efficiency, and renewables. Comparable mission, France-only scope, and intellectual leadership role in the energy-transition debate.
• Hespul: French non-profit association promoting renewable energies and energy efficiency at the local level. Closely comparable mission and member-based advocacy model to Cler, focused on solar PV and renewable-energy deployment.
• RARE - Réseau des agences régionales de l'énergie et de l'environnement: National network of regional energy and environment agencies in France, structurally similar to Cler as a federation of territorial energy-transition actors. Closely comparable in mission, member model, and convening role at the territory level.
• Réseau Action Climat (RAC): French federation of climate-action associations coordinating European climate advocacy. Comparable membership-based model, national coordination role, and advocacy/lobbying function that overlaps directly with Cler's policy work.
