Life Cycle Assessment and Greenhouse Gas Emissions from Animal Agriculture

How much greenhouse gas does animal agriculture emit? How does that compare to other industries? This video for the Animal Agriculture in a Changing Climate Project describes how a Life Cycle Assessment (LCA) quantifies greenhouse gas emissions from animal agriculture.
The project thanks Dr. Frank Mitloehner, University of California – Davis and Dr. Greg Thoma, University of Arkansas, for their contributions to this video.
