U.S. Counting on Cows to Reduce Carbon Emissions

U.S. Secretary Tom Vilsack announced an agreement with the American dairy industry Tuesday to reduce the industry's greenhouse gas emissions 25 percent by 2020, mostly by convincing farmers to capture the methane from cow manure that otherwise would be released into the atmosphere. "This historic agreement, the first of its kind, will help us achieve the ambitious goal of drastically reducing greenhouse gas emissions while benefiting farmers," Vilsack said at the U.N. climate talks. "(The) use of manure of technology is a win for everyone." Agriculture accounts for about 7 percent of the greenhouse gas emissions in the United States. The plan calls for persuading more American farmers to purchase an anaerobic digester, which essentially converts cow manure into electricity. The problem is that, so far, only 2 percent of U.S. dairy farmers are using the technology, mostly because it is too costly for family farmers. There are more than 60,000 dairy farms with about 9 million dairy cows in the United States, but 77 percent of the farms have fewer than 100 cows, according to Dairy Farming Today, an industry group. Farms that would be interested in this technology would likely have more than 100 cows. Thomas Gallagher, the chief executive officer of the Innovation Center for U.S. Dairy and Dairy Management Inc., which signed the agreement with the government, said the commitment shows that U.S. farmers are concerned with making their operations increasingly sustainable...read more
