Food buyers alliance targets green ammonia production

The Center for Green Market Activation, RMI, and 3Degrees have launched the Green Ammonia Buyers Alliance, creating a collective procurement route intended to help food and beverage companies support lower-emission fertiliser production.

The initiative, known as GABA, will aggregate demand from downstream buyers and use a book-and-claim system through which participating companies purchase environmental attribute certificates from verified green-ammonia producers.

The model is designed around an awkward feature of the agricultural supply chain: major food businesses can have substantial emissions associated with fertiliser without ever purchasing ammonia or fertiliser themselves. Crops can pass through growers, traders, merchants, processors, and ingredient suppliers before reaching the food factory.

GABA says food and beverage companies can sit five or six steps downstream from ammonia production, making direct physical procurement impractical even where those businesses have Scope 3 targets covering agricultural inputs.

Ammonia is a fundamental feedstock for nitrogen fertiliser and conventional production is heavily dependent on natural gas. Green-ammonia projects instead use renewable electricity to produce hydrogen from water through electrolysis before combining the hydrogen with nitrogen to manufacture ammonia.

The alliance is attempting to create a financial link between downstream food buyers and those production projects without requiring the physical ammonia covered by a purchase to end up on the farms supplying a particular manufacturer.

Under the book-and-claim approach, the environmental attribute associated with qualifying production is separated from the physical commodity. Members can buy certificates from verified green-ammonia producers while conventional fertiliser and agricultural commodities continue to move through existing distribution networks.

That removes an enormous traceability burden. A physically segregated chain could require ammonia, fertiliser, crops, and ingredients to remain linked through several independent businesses before a food manufacturer could claim the final agricultural input came from a particular low-emission production route.

The certificate model avoids that physical segregation, but it places more pressure on accounting and verification. The environmental attribute must have clear ownership, projects have to meet agreed eligibility criteria, and the system has to prevent the same emissions benefit being claimed by more than one participant.

There is also a distinction between supporting lower-emission production and changing the actual fertiliser used by a company’s own suppliers. A food manufacturer buying an environmental attribute certificate cannot reasonably state that every tonne of grain entering its factories was grown using green-ammonia fertiliser unless the physical supply chain supports that claim.

The alliance instead gives companies a way to direct money towards verified production while assigning the associated environmental benefit under an agreed accounting framework. That type of market mechanism has already been used in renewable electricity and is being applied increasingly to harder-to-abate sectors where physical segregation is expensive or impractical.

For green-ammonia developers, demand certainty is the central issue. Numerous projects have been announced globally, but large plants require substantial investment in renewable generation, electrolysers, hydrogen systems, air separation, ammonia synthesis, storage, and export or distribution infrastructure.

Developers need confidence that buyers will pay for the lower-emission product before committing that capital. Aggregating several downstream companies through a competitive procurement process is intended to create a stronger and more bankable signal than individual food businesses making small or informal commitments.

GABA says member companies will purchase environmental attribute certificates directly from verified producers, helping provide revenue certainty to projects while giving food businesses a route to address fertiliser-production emissions that sit outside their direct procurement activity.

The potential scale is significant. The alliance estimates that the wider fertiliser value chain generates around 1.2 gigatonnes of carbon-dioxide equivalent annually, although the proportion attributed to an individual food manufacturer varies widely by crop, sourcing geography, farming practice, and product mix.

Energy exposure provides another commercial consideration. Conventional ammonia economics are closely tied to natural gas, leaving fertiliser prices vulnerable to energy-market volatility. Green ammonia has different cost pressures, particularly around renewable electricity and plant capital, but a larger production base could diversify the feedstock routes available to the fertiliser industry.

The model builds on an existing food-sector procurement programme. The Low Carbon Fertilizer Alliance, led by 3Degrees, comprises 25 food and beverage companies and focuses on measures including blue ammonia and nitric-acid decarbonisation at existing fertiliser plants.

GABA is intended to complement that programme by directing collective demand towards renewable-based ammonia. The organisations have not named the founding food and beverage companies in the launch announcement, so the size and composition of the first procurement will provide a better indication of how much buyer demand has actually been assembled.

Manufacturers will also have to decide how certificate purchasing fits alongside work on their physical agricultural supply chains. Many food companies are already asking suppliers for farm-level information covering fertiliser application, soil management, crop rotations, and greenhouse-gas emissions.

A certificate can address part of a corporate emissions strategy, but it does not provide the agronomic information needed to understand whether fertiliser is being used efficiently on the farms physically supplying ingredients. The two approaches can therefore operate alongside one another rather than acting as substitutes.

The credibility of environmental claims will be similarly important. Food manufacturers are under increasing pressure to substantiate carbon statements, and any book-and-claim system will need clear rules explaining what a certificate represents and what the buyer can legitimately report.

GABA’s organisers say their model draws on collective procurement structures used in renewable electricity, sustainable aviation fuel, lower-emission shipping, heavy-duty transport, and construction materials. The alliance is also aligning its approach with developing corporate guidance around value-chain interventions.

The first pilot procurement is planned for the fourth quarter of 2026. Participating buyers are expected to help shape the programme while purchasing through a competitive process, with the launch material also referring to first-mover pricing opportunities through 2027.

That procurement will provide the first practical test of the model. Certificate volumes, project eligibility, pricing, buyer participation, verification, and contract duration will determine whether the alliance creates enough demand certainty to influence investment decisions rather than simply producing another corporate sustainability mechanism.

For food manufacturers, GABA pushes procurement intervention unusually far upstream. The participating company may never physically receive the ammonia or the fertiliser produced from it, but the model is designed to make its purchasing power visible at the point where one of agriculture’s most emissions-intensive inputs is manufactured.
