Proba, a startup focused on certifying Scope 3 emissions reductions in the agri-food supply chain, has raised €1.25 million to support market expansion into the United States and Brazil. The round included participation from existing investors Future Food Fund, Yield Lab Europe, and Value Factory Ventures.
The company certifies fertilizer-related emissions reductions and other climate interventions as verified Scope 3 outcomes, targeting a major source of agricultural emissions. Proba notes that emissions from nitrogen fertilizers alone account for approximately 5% of global greenhouse gas emissions. For many staple crops, the emissions from fertilizer production and in-field use represent a significant share of the overall carbon footprint, creating a near-term opportunity for measurable reductions where proven low-carbon fertilizer solutions already exist.
Proba positions its platform to accelerate adoption by addressing common barriers across complex supply chains, including cost and misaligned incentives among producers, traders, cooperatives, and food companies. By making fertilizer-related reductions measurable, financeable, and credible, Proba aims to help large agri-food companies deliver reductions that are compliant, traceable, and scalable across major crop value chains such as coffee, corn, potatoes, and sugar.
A core element of Proba’s model is its “Impact Units,” traceable certificates that represent 1 tCO₂e of verified reduction linked to specific practices. Proba says the approach is designed for credible Scope 3 accounting and aligns with SBTi and the GHG Protocol’s FLAG guidance, supported by independent verification and a registry to enable traceability.
The new funding is intended to strengthen Proba’s ability to serve global customers in two of the most important agricultural regions, as it scales certification and financing mechanisms for fertilizer-related emissions reductions across the Americas.
KEY QUOTES
“Our ambition is to make fertilizer-related Scope 3 reductions standard practice in global agri-food supply chains. This funding accelerates that mission by enabling us to operate in the regions that matter most to our customers, particularly the United States and Brazil.”
Sijbrand Tieleman, CEO and Co-Founder, Proba
“Proba addresses one of the most material and under-accounted sources of emissions in the agri-food sector. Their approach combines strong scientific grounding with a practical pathway for companies to act on Scope 3. We see significant potential for their model as companies face increasing pressure to deliver verified results.”
Kim Wagenaar, Investment Director, Future Food Fund
“Proba has shown strong momentum, and we’re pleased to support their continued growth as they expand into new markets.”
Daan Wilms van Kersbergen, Investment Director, Yield Lab Europe
“Proba is already delivering real, measurable impact, turning fertilizer-related emission reductions into results companies can credibly report. That traction strongly fits Value Factory’s focus on deeptech with measurable climate impact, and we’re excited to keep supporting Proba as they accelerate and expand into the US and Brazil.”
Johan van Heusden, Managing Partner, Value Factory Ventures
