Archer-Daniels-Midland is entering the voluntary carbon dioxide removal market with more than 800,000 tons of annual removal capacity tied to its corn processing complex in Columbus, Nebraska — an offering the company describes as one of the largest of its kind to date.

The credits will be generated from carbon capture and storage (CCS) operations already running at the Columbus facility. ADM launched those operations in 2025 in partnership with energy infrastructure company Tallgrass, capturing biogenic CO2 released during ethanol fermentation. After capture, the gas is purified and compressed, then transported to Tallgrass's sequestration hub in eastern Wyoming, where operators store it underground in state-regulated CCS injection wells. ADM calls the project the largest bioethanol carbon capture facility in the world.

The distinction matters for the credits themselves. Because the CO2 originates from fermentation of corn grown in the same agricultural cycle, the stream counts as biogenic, positioning ADM to sell into voluntary removal markets that treat geological storage of biogenic CO2 as durable carbon removal rather than mere emissions avoidance.

Certification is now the gating step. The credits are undergoing review by carbon-crediting platform Puro.earth under its Geologically Stored Carbon methodology, with certification and issuance of the initial credits expected by the end of 2026. If verification succeeds, ADM expects to open a 15-year crediting period for the Columbus plant — a timeline that effectively locks the facility's removal volumes into the voluntary market through the early 2040s.

Kris Lutt, ADM's Vice President of Innovation & Growth, framed the move as an extension of the company's core processing footprint.

"Our growth strategy is predicated on smart investments that build on our world-class footprint, and carbon capture is a great example of that," Lutt said. "More broadly, we view agriculture as a powerful engine to lower carbon, and our capabilities uniquely position us to help deliver for stakeholders across value chains."

For ADM, the move converts an emissions liability at an ethanol plant into a monetizable commodity stream. It also deepens the company's structural reliance on the Tallgrass transport and sequestration chain in Wyoming — the Columbus project only generates sellable credits if that midstream link keeps operating and its state-regulated wells keep accepting volumes.

The announcement also signals how bioethanol CCS is maturing as a credit category. Fermentation CO2 is nearly pure at the point of capture, which lowers capture costs compared with dilute post-combustion streams, and geological storage under Puro.earth's methodology offers buyers long-duration removal claims that shorter-lived nature-based credits cannot. ADM's scale — a single site above 800,000 tons per year — puts it among the largest single-source suppliers in the voluntary removal market.

What happens next depends on two deadlines. Puro.earth certification and initial issuance are due by the end of 2026; successful verification then triggers the 15-year crediting window. Both will determine whether ADM's Nebraska tonnage actually reaches buyers or stays a paper figure.
