For instance, National Farmers Union's Carbon Credit Program was a multi-state program that allowed farmers and landowners to earn income by storing carbon in their soil through no-till crop production and long-term grass seeding practices. Farmers Union had earned approval from the Chicago Climate Exchange to aggregate carbon credits. Farmers Union was enrolling producer areas of carbon into blocks of credits that were traded on the Exchange, much like other agricultural commodities are traded. The Clearing and Settlement Platform processed all transaction information. The Registry was the official database for Carbon Financial Instruments owned by Registry Account Holders.
