Proba launches AI tool for traceable fertilizer emissions data

Proba has introduced Proba NTree, an AI agent for fertilizer emissions accounting in agri-food supply chains. The tool is built to help food companies, fertilizer producers and other buyers produce traceable Scope 3, SBTi FLAG and CSRD reporting numbers based on product-specific and site-specific data.

Why it matters: - Fertilizer emissions can make up a major share of many food companies’ Scope 3 inventories. - Proba NTree is designed to replace generic emission factors with traceable values tied to the fertilizer product, where it was made and where it is applied. - The approach is meant to make supply chain accounting more defensible for auditors and more useful for decisions about sourcing, fertilizer choice and nitrogen rates.

What happened: - Proba launched Proba NTree, an emission accounting AI tool for fertilizer emissions in agri-food supply chains. - The tool is built for Scope 3, SBTi FLAG and CSRD reporting. - The launch was announced in Amsterdam on Oct. 12, 2026.

The details: - Proba NTree uses two steps. - An AI agent converts a user’s question into the inputs needed for the calculation. - The AI agent asks a follow-up question when information is missing. - Proba’s decision tree selects one scientific method per case across four emission sources. - The system uses only published values. - The AI agent does not generate numbers. - The same input always produces the same result. - Food and beverage companies and retailers can use the tool to calculate fertilizer emissions for crops they source. - Those companies can use the tool to set a baseline for SBTi FLAG targets and CSRD reporting. - The tool can also help test sourcing or farming changes before they are reflected in reported emissions. - Fertilizer producers and distributors can use Proba NTree to show product-specific emission numbers to customers. - Those users can quantify the difference between low-carbon or inhibitor-treated products and conventional alternatives. - Cooperatives, traders and sustainability advisors can process a full sourcing list in one run. - Those users can compare scenarios such as product, origin or nitrogen rate before making a change.

Between the lines: - Proba is positioning NTree as a response to a common sustainability problem: generic emission factors can hide real differences between fertilizers, suppliers and field conditions. - The company is also addressing a trust issue in AI-assisted sustainability tools by separating question handling from calculation logic. - The message to buyers and auditors is that the methodology, not the model, controls the result.

What's next: - Companies can request a half-hour walkthrough of Proba NTree with the Proba team via the NTree product page. - Proba says its broader approach includes independent verification and a registry that supports traceability. - The company will continue targeting credible Scope 3 accounting aligned with SBTi and the GHG Protocol FLAG guidance.

The bottom line: - Proba NTree aims to make fertilizer emissions accounting more traceable, more repeatable and easier for auditors to verify.
