ADM sells carbon removal's scarcest input: the audit trail

Archer Daniels Midland plans to sell carbon credits from a Nebraska corn processing plant that captures more than 800,000 tons of carbon dioxide a year, its first entry into the voluntary carbon market even though it has been putting carbon underground since 2011 without ever selling the result.

The credits will be verified and issued by Puro.earth, the registry named in the announcement, which is reviewing them for issuance under a 2024-updated methodology for Geologically Stored Carbon that covers carbon dioxide captured from the atmosphere or from biogenic material and then injected underground for permanent storage. Corn processing puts the Nebraska tonnes on the biogenic side of that definition, and once certification closes, ADM plans to issue credits from the facility across fifteen years.

Neither the announcement nor the trade coverage attached a price or a credit volume to the programme, leaving the revenue side unstated while the capacity side gets the headline number. Putting the tonnage in front of buyers ahead of certification suggests ADM expects the operating record to do the selling.

Puro.earth's president, Jan-Willem Bode, said the audit process has run exceptionally smoothly, and described ADM as having approached every stage, from measurement and data collection through to third-party audit, with the discipline and transparency that an investment-grade market requires. Registries seldom talk that way about their own clients, and the phrasing is doing work: in geologically stored carbon the commodity is a promise about permanence, and permanence is the one property a buyer cannot inspect before paying.

ADM's own history is what makes the promise checkable. According to the announcement, it was the first U.S. company to operate an Environmental Protection Agency-permitted Class VI injection well, opening its first in Illinois in 2011 and receiving a permit for a second Illinois well in 2017, so the permit file standing behind Nebraska credits predates the current shape of the voluntary market. ADM calls the Columbus plant the largest bioethanol carbon capture facility in the world, a claim that rests on the same operating record.

As this publication has argued, the binding constraint in carbon markets has moved away from the supply of credits and toward the plumbing around them — settlement, assurance, and the rules that let a tonne travel from a project into a balance sheet. ADM's move reads as a supply story, and 800,000 tons a year of additional durable removal is a substantive addition to a market that has struggled to produce it. The reason those tonnes are sellable at all is that they arrive with the plumbing already attached.

A registry methodology written specifically for geological storage, a third-party audit under way, and an injection history that starts in 2011: that combination is the constraint here, not the capture equipment, which is engineered from known parts. The supply curve for geologically stored credits will be built by operators who already hold permits and have run wells, a group that looks far more like agricultural processors than like the project developers who defined the category.

ADM's vice president of innovation and growth, Kris Lutt, framed the offering as a way to reach customers across multiple industries, from technology and finance to aviation and pharmaceuticals, and credited the company's own injection wells, Tallgrass's capabilities, and other partnerships for letting ADM connect agricultural production with growing carbon removal markets at scale. The fifteen-year issuance schedule is the tell: a credit stream that amortises a capture asset bolted to a corn plant is infrastructure finance, and if it prices that way, the removal tonnage behaves like a byproduct that helps pay for the capture rather than a standalone product competing for its own capital.

ADM is working the other end of the durability range in parallel. Earlier this year it partnered with Hill's Pet Nutrition to expand adoption of regenerative agriculture, enrolling 16,000 acres of corn and soybean fields across a pair of U.S. states and 2,500 acres of soybean in Hungary over multiple years, and its 2025 regenerative agriculture report said the company met a 2025 goal of moving 5 million acres to regenerative practices. Soil-based programmes and geologically stored credits sell to different buyers on different timelines; the durable end is likely to hold pricing longest, because that is where a buyer with a hard removal target has the least room to substitute something else.

For all the capacity language, the gate is procedural. Puro.earth is reviewing the credits for issuance, and ADM's fifteen-year clock starts when that review closes. What a geologically stored tonne from a corn plant is actually worth is the next argument — and whether the operator holding the permit file or the buyer holding the target ends up setting that price.
