The FARM Environmental Stewardship module helps tell that story for dairy farmers. This program silo details a comprehensive estimate of greenhouse gas emissions and energy use on dairy farms, and provides tools and resources for farmers to measure and improve their footprint.
The tool is based on a life cycle assessment (LCA) of fluid milk conducted by the Applied Sustainability Center at the University of Arkansas published in 2013, incorporating data from more than 500 dairy farms across the United States. The FARM Environmental Stewardship module asks a set of questions to assess a farm’s carbon and energy footprint – reducing the burden on farmers while still providing reliable, statistically robust estimates that explain 98% of the variability in total carbon footprint.
One cow in 2007 produced fives times as much milk as one cow in 1944
From 1944 to 2007, the carbon footprint of a gallon of milk decreased by
