Low Carbon Fuel Standard

The Low Carbon Fuel Standard (LCFS) is a state program established by the California Air Resources Board (CARB) that seeks to reduce the carbon intensity of transportation fuels in the state.  Refueling station operators that dispense low carbon fuel, such as natural gas, are granted LCFS credits by the state of California that can be sold or traded.  For more information, please visit the CARB LCFS website*.

LCFS Revenue Return Program

In accordance with California Public Utilities Commission, revenue from the sale of utility LCFS credits generated at utility-owned compressed natural gas vehicle stations is being returned to customers in the form of a rate credit that reduces the pump price at utility stations. The current rate credit can be found by accessing the SoCalGas® Schedule G-NGV for stations owned and operated by SoCalGas and the SDG&E® Schedule G-NGV* for stations owned and operated by SDG&E.
