Though we’re pretty good at raising premium-quality sustainiBeef, when it comes to climate science, we prefer to leave the research to the professionals.

 Climate scientists use a method of research called a Life Cycle Assessment (LCA) that accounts for emissions throughout the entire supply chain. LCAs are the gold standard for carbon footprint comparisons in many industries- not just food production.  Highly sensitive and expansive models enable researchers to isolate individual variables to analyze their emission impact.

UC Davis Researchers found the following:

  • The majority of the CO2 emissions associated with beef production are attributed to the cows that produce the steers, not the steers themselves.
  • steers resulting from a dual-purpose Holstein cow herd have a tremendously lower level of CO2 equivalent (CO2e) emission than steers resulting from a traditional beef background- both with and without a stocking phase.
  • More accurate biogenic calculations that include the recycling of livestock manure as carbon-sequestering fertilizer provide a much lower net CO2e impact than previously attributed to beef production.

Study findings:

Because our supply chain combines Angus genetics with a California-based Holstein mother-cow herd, the environmental footprint described in the study is undoubtedly representative of sustainiBeef’s CO2e output.
