Envision Energy has transferred the first environmental attributes linked to 1,000 tonnes of low-carbon ammonia to PepsiCo’s Asia-Pacific business under a book-and-claim agreement running from 2026 to 2030.
The transaction does not involve shipping that physical ammonia to PepsiCo. Environmental attribute certificates generated by production at Envision’s Chifeng Net Zero Industrial Park are recorded, allocated, and retired through an S3 Markets registry.
Envision estimates that the first certificate delivery could correspond to an emissions-reduction opportunity of about 5,000 tonnes of carbon dioxide equivalent. The figure is preliminary, while the use of the attributes in Scope 3 reporting remains subject to applicable standards, claims guidance, and PepsiCo’s internal controls.
The distinction between product and attribute is the centre of the arrangement. Low-carbon ammonia is produced in one location and can enter an available physical market, while the associated emissions benefit is separated and assigned to a buyer elsewhere. That buyer pays for the attribute without requiring the molecules themselves to travel through the same supply chain.
Book-and-claim systems are intended to address a familiar industrial problem: low-carbon production can exist before dedicated transport, storage, and distribution networks are extensive enough to connect every producer with every customer. Separating the attribute allows demand to support production while physical infrastructure develops.
It also creates an accounting problem that must be handled with more discipline than the phrase “certificate purchase” suggests. Each attribute must be linked to identifiable production, measured emissions data, ownership records, sale, allocation, and final retirement. Without that chain, the same reduction could be claimed more than once or detached from the production that created it.
S3 Markets is providing the registry used to issue and manage the certificates. Envision said the system links production, emissions, sales, and retirement documentation to create an auditable chain of custody. The credibility of the transaction therefore depends on the quality of those records and the rules under which external assurance and corporate claims are accepted.
PepsiCo is targeting emissions associated with fertiliser in its agricultural supply chain. Ammonia is a feedstock for products including urea, ammonium nitrate, monoammonium phosphate, and diammonium phosphate, while conventional production commonly relies on natural gas or coal-based routes with substantial greenhouse-gas emissions.
For a food manufacturer, those emissions occur upstream of its own factories but remain connected to crops and ingredients. Fertiliser use is fragmented across farms, countries, suppliers, and product groups, making direct intervention difficult even when the aggregate emissions are material.
The certificate model allows PepsiCo APAC to support lower-carbon ammonia production without changing its existing fertiliser procurement or production arrangements. That makes adoption easier, but it also means the transaction should not be described as a physical switch in fertiliser supply. The commercial and accounting signal moves first; the molecules may continue through a different chain.
Envision’s Chifeng operation provides the production anchor. The company has developed an integrated green hydrogen and ammonia complex using renewable power, with ammonia serving as a storable chemical output for fertiliser, energy, and other industrial markets. The current agreement uses its production data to create certificates for a downstream buyer.
The model may reduce the need to transport a specific low-carbon batch over long distances solely so one purchaser can claim its attributes. That can avoid some logistics cost and emissions, but it does not remove the physical infrastructure required for ammonia production, storage, handling, and sale. It changes the route by which environmental value reaches the buyer.
Whether the model scales will depend on common definitions. “Low-carbon” must be supported by an agreed boundary, emissions methodology, comparison baseline, and treatment of the electricity, hydrogen, nitrogen, conversion, and transport stages. Buyers also need confidence that certificate retirement is exclusive and that claims remain valid as Scope 3 guidance evolves.
The 2026–2030 agreement gives Envision and PepsiCo time to test the mechanism beyond one transaction. Repeated deliveries can show whether registry controls, production evidence, and buyer accounting work consistently, while larger volumes would indicate that certificate demand can contribute to the economics of low-carbon ammonia plants.
Book and claim should not be mistaken for a substitute for rebuilding industrial supply chains. It is a financing and allocation tool that can direct money towards lower-carbon production and connect that production with dispersed demand, but it cannot replace physical fertiliser availability, farm-level efficiency, or verified reductions in the underlying process.
The first 1,000 tonnes of attributes is therefore a limited but useful industrial test. Its value will depend on whether the system preserves a defensible link between production and claim — and whether subsequent transactions help expand actual low-carbon ammonia output rather than merely creating a more elaborate market for paperwork.
