After several years of stuttering progress, the idea that carbon credits can be used to fund regenerative agriculture took a leap forward this week with the release of what might be the largest-ever tranche of farmland credits. In a separate move, a national government announced that it would buy hundreds of thousands of credits from another project developer.
The Danish startup Agreena said Monday that the carbon credit registry Verra had verified its work with farmers in 10 European nations, resulting in the release of 2.3 million credits. Farmers earned the credits by deploying regenerative agriculture techniques on close to 4 million acres over the past three years. The methods, including the use of cover crops and reduced tillage, store carbon in soils and reduce emissions from farmland operations. Potential co-benefits include improved yields and better water retention.
Radisson Hotel Group and Ryanair are among 15 companies that have purchased credits, said Simon Haldrup, Agreena CEO and co-founder.
Price points
The news is the latest milestone for a field that previously promised more than it delivered. A flurry of soil carbon startups launched at the start of the decade, but delays ensued after Verra and other registries took longer than expected to approve projects. This May, the U.S.-based project developer Indigo Ag issued 500,000 credits — its fourth annual batch — and said that farmers in its network, which spans 28 states, had stored almost a million tons of carbon dioxide in soils.
“Soil carbon and regenerative ag fits the bill with a lot of the corporate buyers,” said Haldrup. “Both from a carbon and integrity perspective, but also from all the co-benefits and a reasonable price point.”
Haldrup declined to share the price of Agreena’s credits, noting that the company is still working to understand the market. Rather than sign long-term offtake agreements, as have become common in other areas of the carbon market, Agreena will be relying on spot market sales in the immediate future. Ewan Lamont, head of sustainability solutions at Indigo Ag, told Trellis in May that his company’s most recent credits cost between $60 and $80 per ton.
National interest
Another buyer with confirmed interest in the sector is the government of Singapore. Boomitra, a project developer that works with farmers in lower-income countries, said yesterday it will deliver 625,000 soil carbon credits to the government between 2026 and 2031. The credits will be generated by paying ranchers in Paraguay to use regenerative grazing practices and will be used by Singapore to help meet its Paris Agreement emissions commitment.
The surge in interest is in part due to increasing confidence in the models used to estimate the carbon removals and avoided emissions associated with regenerative agriculture. Microsoft, a company known for conducting extensive due diligence before buying carbon credits, contracted for 40,000 tons from Indigo in 2024.
Yet open questions remain about the long-term capacity of farm and ranch soils to store carbon, as well as the reliability of the models. Soil sampling remains the most accurate method for measuring soil carbon, but it is too expensive to carry out on every field. Holdrup said Agreena took 200,000 samples last year across its network and collected 100 data points from each field, including information from farmers on crops planted, tillage and fertilizer use. Satellite imagery is also used to confirm where and when specific crops were planted.
