EDF's Sustainable Sourcing Initiative aims to promote sustainable grain production practices to feed a growing population while stabilizing the climate and protecting resources. EDF collaborates with various players in the food supply chain including farmers, retailers, grain buyers, and technology companies. Current collaborations include working with Smithfield Foods/Murphy-Brown to promote optimal fertilizer management and with United Suppliers to advance their program targeting nutrient use efficiency and soil health on 10 million acres by 2020. EDF looks to expand these types of collaborations to other industries like beef and help set goals and engage the supply chain to improve practices around fertilizer optimization and soil health.
