The U.S. dairy industry has completed a comprehensive study of the carbon footprint associated with the production of a gallon of fluid milk, and the findings validate the results of other studies that have put the associated greenhouse gas (GHG) emissions of all dairy products at only about 2% of total U.S. emissions.

For the study, researchers followed the lifecycle of a gallon of milk - from the beginning when crops are grown to feed cows, to when milk is produced and delivered to processors, through processing, packaging and distribution and all the way to the purchase and disposal of the gallon of milk by the consumer.

Involved were 500 farm and 50 processing plants across the U.S. as well as more than 210,000 round trips transporting milk from farm to processor. From a processing standpoint, the study represented 25% of all fluid milk in the U.S.

The Innovation Center for U.S. Dairy commissioned the University of Arkansas' Applied Sustainability Center to conduct the GHG lifecycle assessment of fluid milk, also called the carbon footprint study. Dr. Greg Thoma, professor of chemical engineering at the University of Arkansas...
