The Proba Registry is the public record of every project registered with Proba, with its key data and full documentation in one place. Every project is quantified under one or more of our science-based methodologies and can be traced from issuance to retirement, so anyone can see where a reduction came from and when it was claimed.

Proba offers science-based methodologies to quantify, monitor, and certify GHG reductions in agri-food supply chains. They provide a compliant foundation for carbon projects, ensuring results can be used in credible Scope 3 claims under frameworks like the GHG Protocol and SBTi.
