Field to market

Quantify and certify fertilizer emission reductions your farmers generate, connect them to buyers who need Scope 3 results, and scale across crops, geographies, and supply chains.

For Food and Ingredient Companies

Not a fertilizer producer, trader, or food company? If you’re developing, financing, or supporting agri-food interventions, Proba can help you turn impact into verified results.

Let's talk

Fertilizer emissions can make up to 40% of crop-related Scope 3 emissions. But for most of the supply chain, they’re invisible, unmeasured, and unclaimed.

  • You can’t hit targets if you can’t track them.
  • Your buyers will start asking (if they haven't already).
  • And if you’ve already made the change, you’re not being paid for it.

Proba is conditionally endorsed by ICROA. Every reduction is independently verified, using sourcing-region or farm-level traceability, in line with the latest GHG Protocol requirements (Land Sector and Removals Standard) and SBTi FLAG targets.

Proba’s products are built with academic partners and the International Fertilizer Association, Proba’s system is audited annually to meet the ICROA Code of Best Practice, ensuring program-level integrity and credible results you can rely on.

How does it work?

Identify & quantify

We identify high-impact supply chain opportunities and quantify GHG savings using our science-backed methodologies.

Verify & issue

Independent auditors verify results according to SBTi and GHG Protocol standards. Reductions can be reported in Scope 3 or issued as Inset Units.

Connect & transfer

We support the transfer of verified emission reductions across the supply chain, confidently and compliantly report them in Scope 3.

Identify & Quantify

We identify high-impact supply chain opportunities and quantify GHG savings using our science-backed methodologies.

Verify & Issue

Independent auditors verify all results to SBTi, GHG Protocol (FLAG), and ICROA standards. We issue certified Impact Units.

Connect & Transfer

We connect your certificates to buyers with Scope 3 goals. Our blockchain registry and MRV tools ensure credible climate claims.

Case study: Agrifirm

Proba Document Logo (2)

Agrifirm Plant-Based Solutions and Proba are working together to cut fertilizer-related crop emissions across arable supply chains. Farmers adopt low-carbon and controlled-release fertilizers, supported by nitrogen stabilizers. Proba quantifies and verifies the resulting emission reductions, enabling food companies sourcing from these chains to report the verified reductions in Scope 3.

Your farmers cut emissions. Can you sell that?

"Every tonne of coffee, soy, or palm oil ends up on your buyer's balance sheet as a Scope 3 emission. Nestlé, Unilever, JDE all have targets they can't hit without you, and they're asking for reductions they can trace, not estimates."

A BETTER AGRI-FOOD INDUSTRY

Transform low-carbon fertilizer technologies into verified impact

The technology for sustainable fertilizers already exists. Proba helps you quantify and certify the emission reductions achieved by integrating these innovations into your supply chain, enhancing transparency, unlocking co-financing, and strengthening sustainability claims.

We certify impact from greener production processes, such as:

  • Introducing Enhanced efficiency fertilizers
  • Improving nutrient use efficiency (NUE) practices
  • Switching to of low-carbon fertilizers

By converting reductions into verified, tradable certificates, we turn sustainability efforts into measurable value.

ONE STANDARD

Certify fertilizer decarbonization with confidence

Proba is setting the standard for insetting in fertilizer-related decarbonization in the agri-food sector. Leveraging deep industry expertise and collaborations with global leaders like the International Fertilizer Association (IFA), we ensure faster, more efficient decarbonization tailored to the complexities of the agri-food supply chain.

Our proven approach integrates seamlessly across logistics, distribution networks, farmer management systems, and agronomical best practices.

Combined with robust MRV (Monitoring, Reporting, and Verification) frameworks, Proba turns your decarbonization efforts into measurable, verified impact while unlocking co-financing opportunities and driving product innovation.

How to decarbonize coffee? Look at fertilizers.

"Fertilizers are an essential input for coffee production, but they’re also one of the largest sources of nitrous oxide (N₂O). Downstream companies often assume these emissions are beyond their control. They’re not."
