Farmers across Agrifirm’s arable supply chains adopt low-carbon fertilizers, controlled-release fertilizers and nitrogen stabilizers, which lower emissions and keep more nitrogen working in the field instead of being lost. Proba quantifies and certifies the reductions, so food companies sourcing from Agrifirm can report them in their own Scope 3 inventory, traceable to the farms where they happened.

For years they’ve used fertilizer practices that lower emissions and make their farming more resilient, without getting full credit for it. Proba built on the Cool Farm Tool data they already had and added the fertilizer-specific detail generic accounting misses, such as the exact nitrogen stabilizers they use. The result is a footprint that follows real field conditions, in numbers they can report and have verified.
