Studies show no food choice results in more greenhouse gas emissions than beef. But many consumers viewing “climate-friendly” claims, like those made by Brazen Beef, an initiative of Tyson Foods, are likely to assume that purchasing beef bearing such a label will help reduce greenhouse gas emissions.
By any measure, beef is a bad choice for the climate. Per gram of protein, beef production results in approximately nine times more greenhouse gas, or GHG, emissions than poultry, six-and-a-half times more than pork and 25 times more than soybeans.
Brazen Beef claims to rely on “innovative, reliable farmers who raise crops using agricultural practices that can help reduce GHG emissions,” citing changes in tillage, the adoption of cover crops and better nutrient management. It also says that ranchers must meet the criteria of Tyson Foods’ Climate-Smart Beef Program, which includes an auditing process and data sharing that is “used in a model that estimates GHG emissions.”
Brazen Beef claims its GHG emissions are already down 10 percent. In support of this claim, Brazen Beef avers that it has “built a model that backs it up.”
