To understand how dairy can be a part of climate solutions, it’s important to be clear about the role it plays in greenhouse gas emissions in the first place, said Dr. Frank Mitloehner, a professor in animal science at the University of California-Davis.   “Comparing cows versus cars is a major flaw” in how climate impacts are measured, he said, because agriculture is part of a carbon life cycle, rather than an extraction of resources that have been in the ground for millions of years. “We know every detail about the impact of dairies on greenhouse gases, on air and water pollutants, and so forth. We know what these impacts are, and we know how to further mitigate those,” Mitloehner said.
