Proba Registry

Welcome to the Proba Registry.

Every Proba Inset Unit begins as a verified fertilizer emission reduction, quantified under our science-based methodologies and confirmed by independent third-party verification.

An Inset Unit isn't a generic offset. It stays inside your supply chain. The registry tracks and traces each unit from issuance to retirement, linking it to the specific growers, products, and organizations it came from, so the reduction can be claimed where it happened: in your own Scope 3 inventory, not someone else's.

That's what makes every unit in this registry auditable, traceable, and yours.
