[Let's talk about it](https://proba.earth/contact?hsLang=en) ![Proba - Connect to buyers](https://proba.earth/hubfs/Proba%20-%20Connect%20to%20buyers.gif "Proba - Connect to buyers") ### Proba's end-to-end platform for fertilizer emission reductions enables the commercial pathway from certified emission reductions to Scope 3 claims - traceable, free of double-counting, and in a format that satisfies procurement teams and standards bodies. ### Where full physical traceability isn't possible, we offer compliant chain-of-custody approaches (mass balance, sourcing-region attribution) that hold up to audit. #### Outcomes you can put in your books #### Reductions are quantified and certified against the GHG Protocol (LSRS) and the SBTi (FLAG) , so they can be entered in your GHG inventory and counted toward Scope 3 target progress.
