What Carbonapp does

Carbonapp is a French mission-driven carbon contribution operator founded in March 2021 and headquartered in Rennes, with additional offices in Paris and Barcelona. The company acts as a mandate operator (mandataire) that develops certified low-carbon projects in France and internationally, connecting project developers across forestry, agriculture, construction, and circular economy with large enterprises seeking to offset residual emissions under CSR/RSE programs. Recognized clients include Edenred, DIM, Carmila, Nexity, BackMarket, DHL, Vinci, Crédit Mutuel ARKEA, Météo France, Eurazeo, Groupe Premium, and BPM Group.

The company has built a multi-standard platform supporting Label Bas-Carbone (France), Puro.earth (Finland/Nasdaq-owned), Rainbow Standard (Europe), and Carbon Standards International (Switzerland), with methodology expertise spanning 15+ Label Bas-Carbone calculation methods. Its technology stack includes the Carbonapp Platform (app.carbonapp.fr) for project portfolio management and discovery, MRV (Measurement, Reporting, Verification) tools, and Crystalchain blockchain timestamping for end-to-end data integrity. Co-developed methodologies — including the DEEE reconditioning method (with BackMarket, Carbone 4, and Largo) and Eco-Méthane (with Bleu-Blanc-Cœur) — position Carbonapp as a methodology author, not merely an intermediary.

Carbonapp earns revenue through transaction fees on carbon credit intermediation and professional services fees for full-service project development (certification administration, carbon calculations, dossier preparation, and ongoing project management). Pricing varies materially by standard and project type — approximately 30€/TeqCO2 for Label Bas-Carbone projects and over 200€/TeqCO2 for Puro.earth biochar removal credits — with multi-year contract structures. The company was certified as a Société à mission in October 2024 and operates with a team of approximately 10–50 employees.

Direct peers

• EcoAct: French-origin carbon consultancy (now part of PwC France) that develops carbon offset projects and provides climate strategy services. Comparable as a French-based carbon project developer and intermediary serving enterprise CSR buyers.
• South Pole: Global carbon project developer and climate consultancy that originates, develops, and sells verified carbon credits across nature-based and tech-based solutions. Directly comparable to Carbonapp as both operate mandate/intermediation models connecting project developers with corporate buyers across multiple certification standards.
• Carbone 4: French climate strategy consultancy and carbon project developer with deep Label Bas-Carbone expertise. Directly comparable as a France-anchored carbon intermediary; also a current co-development partner of Carbonapp on the DEEE methodology.
• myclimate: Swiss non-profit that develops and markets high-quality carbon offset projects worldwide, partnering with corporate buyers on voluntary climate contribution. Comparable multi-standard project origination and intermediation model focused on European enterprises.
• ClimatePartner: German-based carbon offsetting platform that helps companies calculate, reduce, and offset carbon emissions through certified climate projects. Directly comparable as a multi-standard project developer and intermediary serving enterprise CSR/sustainability buyers across Europe.

Emerging players

• Sylvera: UK-based carbon credit ratings and analytics platform providing quality assessments of voluntary carbon projects. Adjacent to Carbonapp's intermediation model — Sylvera rates credits while Carbonapp originates and sells them — making it an ecosystem complement rather than direct competitor.
• Climateseed: European platform connecting project developers and corporate buyers around certified carbon credits. Comparable in the marketplace/intermediation model, though smaller and more digitally-native than Carbonapp's human-relationship-led approach.
• Patch: API-first carbon credit marketplace enabling enterprises to embed offsetting into digital products. Emerging player with partial overlap in the intermediation space, focused on tech-driven distribution rather than project origination.

Broad incumbents

• Climate Action Reserve: Established carbon credit registry operating the Climate Action Reserve (CAR) protocol, one of the major voluntary carbon standards. Adjacent rather than directly competitive, but provides the certification infrastructure that Carbonapp and similar intermediaries rely on.
• Verra: Global carbon standards body administering the Verified Carbon Standard (VCS), the world's largest voluntary carbon program. Ecosystem infrastructure provider rather than direct competitor, but sets the rules and registry framework Carbonapp's international projects navigate.
