The United States is counting on cows to help reduce its carbon footprint.
U.S. Agriculture Secretary Tom Vilsack announced a plan Tuesday to reduce greenhouse gas emissions in the dairy industry 25% by 2020, mostly by convincing farmers to capture the methane from cow manure that otherwise would be released into the atmosphere.
Agriculture accounts for about 7% of the greenhouse gas emissions in the United States.
A big part of the plan includes convince more farmers to purchase anaerobic digesters that essentially convert cow manure into electricity. The problem is that until now only 2% of dairy farmers who are good candidates for the technology are using it.
