In July, Burger King released a commercial claiming that adding lemongrass to beef cattle diets would help cut methane emissions by "up to 33 percent." 

Ag industry experts quickly pushed back on the controversial video. One of those experts was world-renowned air quality specialist Dr. Frank Mitloehner, a professor at the University of California – Davis (UC – Davis). His input, along with many others in the ag industry, resulted in Burger King pulling parts of the campaign and issuing an apology to producers. Burger King asked Mitloehner to partner with them to gain science-based insight and fact-check content moving forward. This is a huge success for the cattle industry.

Mitloehner’s research is working toward understanding how cattle can be part of a climate solution. Mitloehner, with the Clarity and Leadership for Environmental Awareness and Research (CLEAR) center at UC – Davis, recently released a video called “Rethinking Methane” explaining how to measure biogenic methane's impact on the environment.
