SoCalGas also recently filed a request with the California Public Utilities Commission (CPUC) to allow customers to purchase renewable natural gas for their homes. SoCalGas aims to have CPUC approval of its voluntary program by the end of the year. Renewable natural gas is a clean fuel produced from our waste streams (i.e., sewers and food waste, as well as dairy and agriculture waste) and can be used like traditional natural gas to heat homes and businesses, for cooking, and to fuel trucks and buses. RNG reduces GHG emissions because it can take more GHG emissions out of the air than it emits as an energy source. In 2016, Governor Brown signed legislation to reduce short-lived climate pollutants, including methane from organic sources. The law requires 40 percent of methane from sewage treatment plants, landfills and agriculture to be captured, with provisions for energy delivery to customers.
