A new two-part study funded by the beef checkoff and the USDA Agricultural Research Service evaluates the sustainability of the U.S. beef industry. The first part of the study says beef cattle production accounts for 3.3 percent of all U.S. emissions. The study says sustainability improvements must be made on an individual operation. A few solutions include shortening the time needed to produce finished cattle, using alternative energy and reducing tillage. A second set of data will determine the environmental impact of the rest of the beef supply chain. That is expected to be released in the next six months. Read more from the first part of the study.
