The greenhouse gas (GHG) life cycle assessment (LCA) for fluid milk was completed in 2010 to establish an industry benchmark of the GHG emissions associated with a gallon of milk. The study identified opportunities for each segment of the U.S. dairy value chain to improve environmental performance.
This was the first national-level fluid milk GHG LCA study in the U.S. Researchers followed the journey of a gallon of milk from the beginning of the life cycle when crops are grown to feed cows; milk is produced and delivered to processors; through processing, packaging and distribution; all the way to the purchase and disposal of the gallon of milk by the consumer.
The study will be published in a special issue of the International Dairy Journal in early 2012.
