Lower Than Perceived Environmental Impacts of Beef Production According to New USDA Study
Harris Ranch Beef Company has a personal stake in the quality of the environment. That’s why we proudly share the results of a study published recently in the journal Agricultural Systems entitled Environmental Footprints of Beef Cattle Production in the United States.1
The report documents the most comprehensive beef cattle lifecycle assessment ever completed. With research conducted by the USDA’s Agricultural Research Service and The Beef Checkoff,2 the assessment was designed to scientifically quantify the sustainability of U.S. beef production. The results show widely accepted measures related to beef cattle’s impact in the U.S. are often overestimated.
At Harris Ranch, we believe raising cattle and environmental stewardship go hand-in-hand. The land is not just where we raise our cattle; it’s also where we raise our families. To us, sustainability means ensuring the land will provide for the next generation by focusing not only on the wellbeing of our livestock, but also on maintaining the land and its natural resources.

The Beef Sustainability: Fact vs. Myth chart provides a quick summary of the true impact of beef production on our environment.
Notable findings published in the Environmental Footprints of Beef Cattle Production in the United States report include:
- Greenhouse gas emissions: Beef production, including the production of animal feed, is responsible for only 3.3 percent of greenhouse gas emissions in the U.S. This is dramatically lower than the often-misapplied global livestock figure of 14.5 percent.3 Furthermore, through continuous improvements in production practices, U.S. beef farmers and ranchers have avoided 2.3 gigatons of carbon emissions since 1975.4
- Grain feed consumption: Per pound of beef carcass weight, cattle only consume 2.6 pounds of grain. This is comparable to feed conversion efficiencies of pork and poultry. Additionally, nearly 90 percent of grain-finished cattle feed is inedible to humans, meaning these plants can only provide value to humans when they’re upcycled by cattle into high-quality protein.
- Corn feed consumption: Corn used to feed beef cattle only represents approximately 9 percent of harvested corn grain in the U.S., or 8 million acres. By comparison, 37.5 percent of corn acreage in the U.S. is used for producing fuel ethanol.5
- Water use: On average, it takes 308 gallons of water to produce a pound of boneless beef. Previous reports have estimated upwards of 24,000 gallons.6 Additionally, water use by beef is only around 5 percent of U.S. water withdrawals, and this water is recycled.
- Fossil fuel inputs. Total fossil energy input to U.S. beef cattle production is equivalent to 0.7% of total national consumption of fossil fuels.
“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,” said Sara Place, Ph.D., study co-author and Senior Director of Sustainable Beef Production Research at the National Cattlemen’s Beef Association7, 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.”

2The Beef Checkoff Program was established as part of the 1985 Farm Bill. The checkoff assesses $1 per head on the sale of live domestic and imported cattle, in addition to a comparable assessment on imported beef and beef products. States may retain up to 50 cents on the dollar and forward the other 50 cents per head to the Cattlemen’s Beef Promotion and Research Board, which administers the national checkoff program, subject to USDA approval.
