A new study, recently published in the journal Agricultural Systems, is the most comprehensive beef cattle lifecycle assessment ever completed. In the report, titled Environmental Footprints of Beef Cattle Production in the United States,(1) the researchers found widely accepted measures related to beef cattle’s impact in the U.S. are often overestimated.
The comprehensive lifecycle assessment, conducted by the USDA’s Agricultural Research Service and The Beef Checkoff, was designed to scientifically quantify the sustainability of U.S. beef production. This was accomplished by collecting and examining feed and cattle production-related data from more than 2,200 cattle producers in seven regional production areas. Conclusions were derived using a simulation model and the regional production data to estimate national impacts in greenhouse gas (GHG) emissions, fossil energy use, blue water consumption and reactive nitrogen loss.
Notable study findings include:
“This lifecycle assessment delivers the most comprehensive and accurate assessment of the environmental impact of beef cattle in the U.S. to date,” said USDA researcher and study co-author Alan Rotz.
The study assessed cattle production in the farm and ranch portion of the beef supply chain, including emissions associated with energy, feed, machinery, seed, pesticide and other resources used in production. Related work is in-progress to assess production further down the supply chain, including processing, packing, distribution, retail, consumption and waste handling. Together, these reports will comprise the most detailed and comprehensive assessment of U.S. beef’s sustainability to-date.
“This work produces baseline data the cattle industry can use to continue to improve the environmental and economic sustainability of U.S. beef,” saidSara Place, Ph.D., study co-author and Senior Director of Sustainable Beef Production Research at the National Cattlemen’s Beef Association, a contractor to the Beef Checkoff. “Investments in this type of research demonstrate a continuous commitment to environmental stewardship by America’s farmers and ranchers.”
