Not a fertilizer producer, trader, or food company? If you’re developing, financing, or supporting agri-food interventions, Proba can help you turn impact into verified result.

Let's talk

Fertilizer emissions can make up to 40% of crop-related Scope 3 emissions. But for most of the supply chain, they’re invisible, unmeasured, and unclaimed.

  • You can’t hit targets if you can’t track this.
  • Your buyers will start asking (if they haven't already).
  • And if you’ve already made the change, you’re not being paid for it.

Agrifirm Plant-Based Solutions and Proba are jointly working on a project cutting fertilizer-related crop emissions across arable supply chains. Farmers adopt low-carbon and controlled-release fertilizers plus nitrogen stabilizers; Proba quantifies the impact and issues third-party-certified emission-reduction units aligned with SBTi FLAG and the GHG Protocol. Food companies sourcing from these chains can claim the verified reductions in Scope 3 reporting.
