Well, actually, the cattle industry in california is a huge methane producer. Methane is eight times worse than carbon dioxide as a global warming problem. So California is working toward getting dairy farmers especially to start collecting manure into biomass digesters to secure that methane, and burn it for our energy use. Really a smart move that should have been done a long time ago. Less than 20% of cow methane comes from belching and farting, and that stuff is hard to capture. California is going after the 80% that is easy and smart to capture.
I am all for a good fart joke. The california cow fart joke is funny. But no one should be taking it seriously as a measure of public policy. see:

“California Regulates Cow Farts,” is how a New York Post headline put it, implying it was a wacky move by Gov. 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.
In California, most methane emissions are from cows — chiefly the state’s 1.7 million dairy cows, whose manure is typically washed into methane-spewing lagoons. This is why the state, which has pledged to reduce methane emissions by 40 percent by 2030, is looking to the big Central Valley dairy farms for substantial reductions.
Its law limiting methane emissions on dairy farms was passed last year but does not mandate any action before 2024. In the meantime, the state is trying to persuade hundreds of big dairy farms to install contraptions known as methane digesters.
