Ruminant Livestock Emissions, photo collage.Globally, livestock are the largest source of methane from human-related activities – and in the U.S., the third largest source. Livestock production can also result in emissions of nitrous oxide, a very potent greenhouse gas, and carbon dioxide, the most abundant greenhouse gas. Fortunately, there are ways to reduce greenhouse gas emissions from livestock production through management strategies that improve production efficiency and result in lower emissions per unit of milk or meat produced.

To find out more about livestock emissions and how the adoption of improved livestock production practices can help to reduce the emission of greenhouse gases, check out the following sites:

  • Frequent Questions. Questions and answers about how methane is produced from livestock and what measures can be done to reduce these emissions.
  • Resources and Tools. Information and models to measure and evaluate livestock production impacts on methane emissions.
