Report shows California LNG fleet was 98% biobased in 2021

In Washington, Natural Gas Vehicles for America (NGVAmerica) and Coalition for Renewable Natural Gas (RNG Coalition) announced that California fleets fueled with bio-CNG achieved carbon-negativity last calendar year for the second straight year.  

Ninety-eight (98) percent of all on-road fuel used in natural gas vehicles in California in 2021 was renewable natural gas (RNG). According to data from the California Air Resources Board (CARB) the annual average carbon intensity score of bio-CNG in that mix was -44.4 gCO2e/MJ.

Moreover, the carbon intensity of California’s bio-CNG remains well below zero today.  Data from Q1 2022 puts the carbon intensity average of bio-CNG at -61.4 gCO2e/MJ.  Q2 2022 data is expected to be released at the end of this month.
