Producing a liter of milk in California emits less greenhouse gas and uses less land and water than it did in 1964, according to a recent study from researchers at the University of California, Davis.

“We compared 1964 through 2014 and found a 50 percent reduction in greenhouse gases to produce the same quantity and quality of milk,” said senior author Ermias Kebreab, professor and Sesnon Endowed Chair in the Department of Animal Science at 51�ԹϺ�� Davis. “The magnitude of change is surprising.”
