SoCalGas Statement in Support of New California Public Utilities Commission, Air Resources Board and Department of Food and Agriculture Dairy Biomethane Pilot Projects


Pilot projects will significantly reduce greenhouse gas emissions in the state by converting dairy waste into transportation fuel


LOS ANGELES, Dec. 3, 2018 /PRNewswire/ -- The California Public Utilities Commission, Air Resources Board and the California Department of Food and Agriculture today announced the selection of six dairy biomethane projects that will significantly reduce greenhouse gas emissions from animal manure by putting dairy methane waste to use as a transportation fuel.  SoCalGas offers the following statement in response to the announcement:

About Southern California Gas Co.: Southern California Gas Co. (SoCalGas) has been delivering clean, safe and reliable natural gas to its customers for more than 145 years. It is the nation's largest natural gas distribution utility, providing service to 21.6 million consumers connected through 5.9 million meters in more than 500 communities. The company's service territory encompasses approximately 20,000 square miles throughout central and Southern California, from Visalia to the Mexican border. SoCalGas is a regulated subsidiary of Sempra Energy (SRE), a Fortune 500 energy services holding company based in San Diego.

"SoCalGas applauds the California Public Utilities Commission, Air Resources Board (CARB), and Department of Food and Agriculture for today's announcement that the state will fund six pilot projects in the San Joaquin and Sacramento Valleys designed to harness methane emissions from dairy digesters and convert that energy into renewable natural gas.

"Renewable natural gas from other states has already begun to clean the air and reduce greenhouse gas emissions in California's transportation sector, which accounts for more than 80 percent of smog-forming emissions and about 40 percent of greenhouse gas emissions in the state. 

"Heavy duty trucks are a significant source of air pollution and greenhouse gas emissions in California. When those trucks are fueled with renewable natural gas, greenhouse gas emissions can be cut by 80 percent or more.  Already, about 70 percent of natural gas trucks in California are fueled by renewable gas delivered by SoCalGas pipelines.

"Renewable natural gas is also a cost-effective way to reduce greenhouse gas emissions in residential and commercial buildings. According to a recent study by Navigant Consulting, Inc., replacing a fraction of the traditional natural gas supply with renewable gas can achieve greenhouse gas reductions equivalent to converting 100 percent of buildings to electric-only energy by 2030.

"Estimates by researchers at the University of California, Davis suggest more than 20 percent of California's current residential natural gas use can be provided by renewable gas made from the state's existing organic waste.

"Today's announcement is an important step in helping decarbonize the natural gas system, while protecting Californians' rights for affordable energy options."
