About Proba

Fertilizers contribute ~5% of global emissions, which makes them a key area for decarbonization. With Proba, agri-food businesses can quantify, verify, and report emission reductions from fertilizer-related interventions within their supply chains using Impact Units. These units facilitate the financing and scaling of GHG emission reduction projects, which benefit each supply chain member, and our planet.
