California's Holy-Cow Idea: State wants its dairy farms to capture methane and sell it as truck fuel
By Bloomberg.
"California Regulates Cow Farts," is how a New York Post headline put it, implying it was a wacky move by Governor Jerry Brown. In fact, California's methane law represents a serious attempt by America's biggest dairy state to come to grips with a potent greenhouse gas.
Methane is responsible for about a quarter of human-generated global warming. While it's not nearly as prevalent as carbon dioxide, and it breaks down in the atmosphere faster, methane is many times more effective than CO2 at trapping heat. And avoiding a man-made climate catastrophe will require limiting emissions from farms as well as oil and gas pipelines, landfills, and other sources.
