Rice paddies are an unlikely battleground in climate finance, but CarbonFarm is wagering they represent one of agriculture's largest untapped opportunities for emissions cuts. The Paris-based startup announced a €7 million Series A round on Oct. 13, led by Colam Impact and backed by an alphabet soup of development finance institutions and climate investors spanning three continents.
The oversubscribed round drew Proparco, Suma Capital, elea, Working Capital Fund, Albo and France's public investment bank Bpifrance. Returning investors Serena & makesense (via their Racine² fund) and Techmind also participated. Founded in 2021, CarbonFarm has now raised €9.5 million total, according to Axios Pro Rata and a company press release.
The timing is hardly accidental. Rice cultivation accounts for a meaningful slice of global methane emissions, and the infrastructure to monetize reductions has only recently materialized. Verra, one of the world's dominant carbon registries, approved its first rice-methodology credits last October. Gold Standard issued its own rice methane credits around the same time. Corporate interest followed swiftly: Google signed a one-million-ton rice-methane credit deal with India's Mitti Labs in September, while Amazon inked an offtake agreement with the Good Rice Alliance in April, TechCrunch reported.
What CarbonFarm offers is satellite-based monitoring married to AI, tracking water-management practices like alternate wetting and drying at the individual paddy level. The startup verifies methane and water reductions for certification under Verra's VM0051 Improved Rice Management methodology and Gold Standard's AWD framework. In January, the company integrated Regrow Ag's DNDC Tier 3 model to layer process-based soil modeling onto its remote-sensing capabilities, per a company announcement.
The pitch is end-to-end support: project design, financing, certification and credit sales bundled into one service. It's a model designed for scale in a sector where fragmentation has long been the enemy of progress.
Co-founder and CEO Vassily Carantino came to agriculture by way of Amazon, where he worked as a product manager, and Columbia Business School. His co-founder and CTO, James Hastwell, studied engineering at the University of Western Australia before earning a master's from École Polytechnique. Neither had deep roots in rice farming when they launched the company, but they saw a category poised to unlock significant climate finance.
Proparco, the French development finance arm within the AFD Group, confirmed a €1 million equity stake tied to the Series A. The round also pulled in Spain's Suma Capital, a climate specialist managing more than €1.1 billion, and Swiss impact investor elea, whose portfolio page lists CarbonFarm with an investment date last year. Working Capital Fund, focused on supply-chain responsibility and worker protections, joined alongside Bpifrance.
"CarbonFarm is building the enabling infrastructure for one of the largest untapped decarbonization opportunities globally," said Benjamine Friderich, investment director at Colam Impact, in the press release. "We believe its combination of project development expertise, climate finance capabilities and digital MRV creates a uniquely scalable platform in the rice sector."
The company's client roster suggests it's threading a needle between corporate demand and on-the-ground execution. Mars Food, Diageo, Ebro, Tilda and BASF Agricultural Solutions appear as partners on the buyer and supply-chain side. Carbon financiers Livelihoods Funds and myclimate are also involved. Development partners span heavyweight multilaterals including the World Bank, Asian Development Bank, SNV, Helvetas and Action Against Hunger. Google shows up as a technology partner.
CarbonFarm says it now operates across 19 countries, though the pace of rollout varies widely. Recent projects include what the company describes as Cambodia's first rice carbon initiative with Amru Rice, announced last December. A sustainable rice program in Vietnam's Mekong Delta with BENEO and Rikolto aims to train more than 1,000 farmers, unveiled in July. India saw what CarbonFarm called the country's first Gold Standard digital MRV rice project with Partners in Prosperity, announced in February. The startup also provides monitoring for UNDP and Ghana's Article 6.2 rice methane pilot.
LinkedIn lists 26 employees as of last week, though the company's official size bracket sits at 11 to 50. The discrepancy is minor but telling in a fast-moving operation still finding its operational footing.
The Series A capital will fund deeper expansion of CarbonFarm's digital MRV and project-development infrastructure. Asia, Africa and Europe remain priority markets, with Latin America targeted for accelerated entry. Proparco's Jean-Gabriel Dayre, co-head of regenerative agriculture, carbon markets and naturetech, called rice decarbonization "a highly promising climate finance opportunity that is beginning to receive the attention it deserves."
Carantino framed the company's strategy as augmentation rather than replacement. "Scale will not come from replacing local value chain players; it will come from equipping them," he said. "They understand the farming systems and have the relationships needed to make change happen. Our role is to help turn this local knowledge into programs that can attract finance and stand up to scrutiny."
It's a pragmatic view in a sector where top-down models have stumbled before. Whether satellite data and AI can truly bridge the gap between smallholder rice farmers and institutional capital markets remains an open question, but CarbonFarm is betting its trajectory on exactly that convergence.
The startup previously raised a €2.5 million seed round in October 2023, led by Racine² and Techmind, with participation from Ponderosa Ventures, AgFunder, Climate Capital and Bpifrance.
