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. 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. The report emphasizes the need for on-farm demonstrations, technical support, and policy incentives to overcome economic and technological barriers.

This paper examines the goals, strengths, and limitations of using Life Cycle Assessment (LCA) within food and agricultural systems. It outlines how LCA provides a systematic, science‑based approach for quantifying environmental impacts across complex agricultural supply chains, enabling improved decision-making, transparency, and sustainability performance.
