FILE - In this March 11, 2009 file photo, a line of Holstein dairy cows feed through a fence at a farm outside Jerome, Idaho. The United States is counting on cows to help reduce its carbon footprint. U.S. Agriculture Secretary Tom Vilsack, in Copenhagen, announced a plan Tuesday, Dec. 15, 2009, to reduce greenhouse gas emissions in the dairy industry 25 percent by 2020, mostly by convincing farmers to capture the methane from cow manure that otherwise would be released into the atmosphere.
