Although livestock management is a small contributor to overall greenhouse gas (GHG) emissions in the United States, it makes up half of all U.S. agricultural emissions. Changes in livestock management can benefit air and water quality and help slow global climate change. This brief summarizes key points from the report "Near-Term Options for Reducing Greenhouse Gas Emissions from Livestock Systems in the United States: Beef, Dairy, and Swine Production Systems," which outlines strategies for managing GHG emissions from livestock systems and reviews options for quantifying and accounting for farm-scale implementation of such strategies.
