Tonight at 10: How UW scientists are working to reduce the cow carbon footprint

Dairy researchers at UW-Madison are breathalyzing cows.

No, they’re not checking to see if they had one too many over the weekend at the terrace– they’re trying to estimate the amount of methane gas the cows are emitting when they process their food.

Scientists say heat-trapping methane has more than doubled in the earth’s atmosphere in the past 200 years and now the dairy industry is trying to reduce its carbon footprint by 25 percent by 2020.

Researchers at the UW are looking into how the cows are fed and how their manure is handled to see if they can help farmers meet that goal.

Monday on News 3 at 10, Eric Franke heads into the barns to learn more about “bovine emissions” and what that means for the environment.
