California’s Top Methane Emitter is a Vast Cattle Feedlot. For Now, Federal and State Greenhouse Gas Regulators Are Giving It a Pass.

Forty miles north of the U.S.-Mexico border in Southern California’s Imperial Valley, the Brandt Company cattle ranch is the largest single point source of methane emissions in the state, releasing more of that greenhouse gas than any oil or gas well, refinery or landfill.

As the production of natural gas from shale fields has expanded, so have methane emissions. U.S. methane emissions grew 27 percent from 1990 to 2009, according to the Energy Information Administration. Methane contributes about 10 percent of all U.S. greenhouse gas emissions and is 25 times more potent a greenhouse gas than carbon dioxide.
