“Any calculation of the carbon footprint of a gallon of milk needs to include fuel used by tractors and trucks, as well as electricity consumed by milking machines and refrigerators. But how much gas is coming from the cows themselves?
That’s the question Purdue University researchers are investigating as they start a new study aimed at measuring greenhouse gases from dairy cows. Albert Heber, principal investigator and a professor of agricultural and biological engineering, said the study is part of an industry-wide effort to reduce greenhouse gas emissions related to fluid milk.
“The dairy industry understands that in order to adopt best practices that will help lower greenhouse gas emissions in the dairy supply chain, it must first know where the mitigation opportunities exist,” Prof Heber said.”
