About
Agreena is a Copenhagen-based agricultural technology company that operates Europe's leading soil carbon program for arable farmers. Founded in 2018, the company has raised over €46 million and has enrolled more than one million acres of European farmland into its regenerative agriculture carbon certification program.\n\nAgreena's platform guides farmers through the transition to regenerative practices — including no-till, cover cropping, and reduced synthetic inputs — and uses a combination of satellite remote sensing and soil sampling to quantify and verify the resulting carbon sequestration. Farmers receive carbon certificates they can sell to corporate buyers seeking high-integrity agricultural carbon credits.\n\nThe company has built strong relationships with European agribusinesses, cooperatives, and food companies seeking to address Scope 3 agricultural emissions. Agreena's approach of combining farmer incentives with rigorous MRV methodology positions it as a key player in Europe's transition to carbon-smart farming, and the company is expanding its program footprint across Central and Eastern Europe.
