What DECARBONEZ ! does

Décarbonez ! is a Société Coopérative d'Intérêt Collectif (SCIC) registered in Vannes, Brittany, France, founded in July 2024 by Association Clim'actions Bretagne. It operates as a citizen investment cooperative that mobilizes individual shareholders (sociétaires), local authorities, businesses, and associations to finance and participate in local renewable energy, energy efficiency, and energy sobriety projects across Brittany. Members acquire parts sociales at €100 each and are organized into four governance colleges: Clim'actions as service producer (Collège A), employees (Collège B), supporters of the Brittany energy transition (Collège C), and project neighbors (Collège D). A cooperative council of seven members, presided over by Coralie Saenz, oversees the entity.

The cooperative's core products are the parts sociales investment instrument and the citizen participation service for local renewable energy project development. Underlying infrastructure is non-proprietary: investment and governance operate through a subscription form (bulletin de souscription PDF), direct outreach, and the inherited communication channels of Clim'actions Bretagne. Distribution is community-led, leveraging the parent association's pre-existing Brittany network (active since 2016), supplemented by partnerships with ADEME, Région Bretagne, Golfe du Morbihan Vannes Agglomération, Fondation de France, Fondation Breizh Biodiv, Kengo (regional crowdfunding), Sén'hélios (sibling solar cooperative), and Université de Bretagne Sud.

Revenue mechanics are not disclosed and the entity is at an early operational stage, having been incorporated mid-2024 with no publicly reported headcount, funding rounds, or financial metrics. The business model relies on mobilizing long-tail citizen capital (€100 per share) to finance small-scale local energy assets and channel returns as dividends, rather than on commercial enterprise contracts. Geographic scope is limited to Brittany and there is no evidence of expansion planning beyond the region.

Direct peers

• Énergie Partagée: National French network and investment vehicle dedicated to citizen-owned renewable energy projects, channeling collective investment into local installations. Highly comparable to Décarbonez!'s model of citizen-funded local renewable energy, though operating as a federation of regional projects across France.
• Enercoop: French citizen-owned cooperative supplying renewable electricity to members and pooling citizen investment in renewable projects. Closely comparable to Décarbonez! in cooperative structure and citizen-financed renewable energy focus, though operating nationally rather than regionally.
• Sén'Hélios: Citizens' cooperative originating from Clim'actions Bretagne's own energy workshop, financing solar projects on municipal buildings in Brittany. Directly comparable to Décarbonez! as a sibling cooperative in the same parent network with identical regional scope and citizen-solar thesis.

Regional players

• EWS Schönau: German citizen-owned energy cooperative that emerged from local opposition to nuclear power and now operates as a regional green utility. Comparable in citizen-led cooperative model for renewable energy, though based in Germany and at much larger scale.
• Bretagne Énergie Solaire: Breton regional initiative supporting solar project development across Brittany. Comparable in regional scope and renewable energy focus, though structured more as a project developer than a citizen-investment cooperative.
• Co-operative Energy (UK): UK member-owned cooperative supplying renewable electricity to households. Comparable in cooperative ownership and renewable energy mission, but focused on retail supply rather than direct project investment, and operating in a different geography.
• SEM Morbihan Énergies: Semi-public local energy company (Société d'Économie Mixte) active in Brittany, investing in renewable and energy efficiency infrastructure at municipal level. Comparable in regional Breton focus and energy-transition mandate, though structured as a public-private entity rather than a citizen cooperative.

Broad incumbents

• Ecotricity: UK green energy supplier that builds its own renewable generation funded by customer bills. Comparable in mission of citizen-funded renewable energy, though operating as a for-profit incumbent at significantly larger scale and serving a different national market.

Emerging players

• The People's Power Station: UK emerging community platform enabling citizens to invest in local renewable energy projects. Comparable in citizen-investment-into-local-renewables thesis and small-scale cooperative ethos, though at an earlier stage of operating history.
• Coopérative Énergie Citoyenne: Regional French citizens' cooperative developing local renewable energy projects with member investment. Comparable in offering citizen equity stakes in renewable projects but typically operating at a smaller, more localized scale than Décarbonez!.
