Companies are now working to measure how soil stores carbon as they encourage farming techniques that reduce emissions across their sprawling supply chains. Regenerative practices can increase soil nutrients and yields while also absorbing carbon dioxide from the air, scientific studies say. PREVIEWMany of the world’s biggest food companies, including General Mills Inc. and Nestlé SA, are working with farmers to promote the practices. The company aims to have 20% of its key ingredients sourced from regenerative agriculture by 2025 and half by 2030. General Mills is now working to include the soil carbon and emissions data into its annual footprint.
