Rice farming feeds half the world, but its flooded paddies are also a potent, diffuse source of methane. The math is simple: a ton of methane warms the planet about 80 times more than a ton of CO2 over 20 years. The problem is that measuring the gas seeping from millions of small, scattered plots has been more art than science, which is why most agricultural carbon projects have steered clear. CarbonFarm Technology, a Paris-based startup, is betting that the view from space can change the economics.
Founded in 2022, the company uses satellite imagery and AI to remotely monitor rice farming practices, quantify methane reductions, and shepherd those reductions through the carbon credit certification process [jobs.makesense.org, Unknown]. Their initial wedge is narrow and deep: rice, and only rice. It is a bet that the combination of a high-impact gas, a fragmented supply chain, and new remote sensing tech creates a window to build a business where others saw only mud.
A bet on rice as a carbon asset
Most climate tech for agriculture tries to be a general farm management platform. CarbonFarm’s bet is different. It assumes that the path to monetizing carbon for smallholders is not through a new dashboard, but through a hyper-specialized measurement, reporting, and verification (MRV) service that can speak the language of carbon registries. The company develops and registers rice-methane projects under major standards like Verra and Gold Standard [LinkedIn, Unknown].
The unit economics of climate action start with measurement. Traditional ground-based MRV for thousands of small farms is prohibitively expensive. CarbonFarm’s model uses satellite data to infer water management practices,a key lever for methane emissions,and AI to translate those observations into emission baselines and reductions. The stated goal is to make projects financeable at scale, with impact claims of “-50% methane emissions” and “+20% smallholder profits” [jobs.makesense.org, Unknown]. The commercial customer isn’t the farmer, but the agri-food company or carbon investor looking to decarbonize a supply chain or portfolio.
The team and the seed
The co-founders, Vassily Carantino and James Hastwell, met through the Entrepreneur First program and started the company in March 2022 [Challenges, April 2026]. The public record on their prior experience is thin, but their investor list suggests credibility in both climate and deep tech. In October 2023, CarbonFarm closed a €2.5 million seed round led by Racine², with participation from Serena, makesense, Techmind, Ponderosa, AgFunder, Climate Capital, and Bpifrance [Jeriko, October 2023]. The capital was earmarked to accelerate the adoption of sustainable rice practices across Asia, Africa, and South America.
The funding has supported a team that, according to a recent recruiting claim, numbers around 20 people [jobs.makesense.org, Unknown]. Their hiring posts tell a story of geographic expansion, with open roles for a Customer Success Manager in Vietnam and Carbon Project Leads in India, pointing to active project development on the ground [LinkedIn, Unknown].
Reported traction and the path to buyers
CarbonFarm does not publish a customer list, but its reported work includes supporting decarbonization efforts for major agri-food companies like Mars Food, Danone, and Ebro [Jeriko, October 2023]. Its geographic footprint is said to span Vietnam, India, Spain, Portugal, and Ghana. For a buyer like a food giant, the value proposition is direct: a verifiable way to cut Scope 3 emissions from a notoriously hard-to-abate agricultural input.
The company’s progress can be inferred from its hiring needs and public positioning. A scan of its open roles reveals the operational build-out required to turn satellite data into certified credits.

Where the model could get stuck
CarbonFarm’s entire business rests on the integrity and scalability of its remote MRV. The risks are not trivial, and they come in three layers.
- Scientific validation. Carbon credit buyers, especially corporates under scrutiny, need ironclad assurance that a ton of CO2-equivalent claimed is a ton actually sequestered or avoided. The company’s methodology must withstand rigorous peer review and registry approval. Any high-profile controversy around agricultural credits could chill the entire buyer market.
- Farmer adoption. The model promises increased profits for farmers, but changing centuries-old practices requires deep local trust and engagement. The “-30% water used” claim is a key farmer benefit, but it depends on practice changes that the satellite monitors, not enables. This is a boots-on-the-ground challenge that pure tech can’t solve.
- Credit market volatility. The company’s revenue is ultimately tied to the price of carbon credits, a market known for its booms and bustes. A sustained price downturn could make projects uneconomical before CarbonFarm achieves sufficient scale to lower its own costs.
The company’s most plausible answer is that specialization is its moat. By focusing solely on rice, it can develop the most credible, cost-effective MRV for that crop, turning a niche into a defensible standard.
The incumbent to beat
Its real competition is the status quo: the costly, manual verification processes that have kept smallholder rice projects out of carbon markets altogether, and the corporate decision to simply buy cheaper, less contentious forestry credits instead. The back-of-the-envelope calculation is stark. If just 10% of the world’s rice paddies adopted the practices CarbonFarm measures, the annual methane reduction could be on the order of hundreds of millions of tons of CO2-equivalent. The question is whether their satellite-driven model can bring the cost of verification low enough to unlock that volume. To win, CarbonFarm must prove its data is not just clever, but bankable, at a scale that makes the incumbent manual audit obsolete.
