This report explores the potential for U.S. agriculture to achieve greenhouse gas (GHG) neutrality or become GHG-negative by integrating current and emerging practices across crop and livestock systems. Agriculture contributes approximately 10% of total U.S. GHG emissions, primarily through carbon dioxide, methane, and nitrous oxide. The analysis identifies five major opportunity areas: soil carbon management, nitrogen fertilizer management, animal production and manure handling, crop production efficiency, and on-farm energy use. Adoption of regenerative practices—such as reduced tillage, cover cropping, precision nutrient management, and improved feed systems—combined with renewable energy technologies could reduce emissions by 80–90% under medium adoption scenarios and achieve net-negative emissions with aggressive implementation. The report emphasizes the need for on-farm demonstrations, technical support, and policy incentives to overcome economic and technological barriers. Achieving GHG-negative agriculture would not only mitigate climate impacts but also enhance soil health, water retention, and production resilience, positioning U.S. agriculture as a global model for sustainable food systems.
