New ARS Study Shows U.S. Beef Is Not a Significant Contributor to Global Warming

An Agricultural Research Service (ARS)-led team has completed a comprehensive life-cycle analysis quantifying the resource use and various environmental emissions of beef cattle production in the United States. Their results so far indicate that U.S. beef's contribution to climate change is small percentage of the country's Greenhouse Gas emissions, and were not a significant contributor to long-term global warming. "The environmental footprint of producing beef has long been debated," said Marlen Eve, ARS deputy administrator for natural resources and sustainable agricultural systems. "One challenge is that the impacts extend beyond just those associated with growing the animals and include the impact of producing feed and other inputs. This is further complicated by the diversity of ways that beef cattle are managed and fed. It is important to have an accurate quantification of these impacts to provide a baseline against which production system sustainability can be assessed and improved." C. Alan Rotz, Agricultural Engineer, USDA-ARS-Pasture Systems and Watershed Management. His collaborators are former ARS research associate Senorpe Asem-Hiablie, Greg Thoma of the University of Arkansas-Fayetteville and Sara Place, with National Cattlemen's Beef Association, which is partially

    It’s a stretch to 3.3% is not a “significant contribution” to GHG emissions.
    3% is still HUGE.
    It needs to be negative 1-2% at least. If the meat industry wants to maintain any credibility going forward.
