October 17, 2022. 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 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.
“For the second straight year, California fleets fueled with Bio-CNG achieved carbon-negativity in their 2021 transportation operations,” said NGVAmerica President Dan Gage. “And since 98 percent of natural gas dispensed in California for use as a motor fuel is from renewable sources, California natural gas vehicle (NGV) fleets consistently achieve a zero-carbon footprint and virtually eliminate criteria pollutant emissions that contribute to asthma, heart disease, and poor air quality.”
In addition to their negative greenhouse gas (GHG) emissions, ultra-low NOx medium- and heavy-duty RNG-fueled trucks and buses perform at levels that are 95 percent below the federal nitrogen oxide (NOx) standard and 98 percent below the federal particulate matter (PM 2.5) standard.
“RNG facilities address methane emissions from society’s inevitable waste streams, mitigate the environmental impacts of those emissions and convert captured methane into domestic, renewable, clean fuel and energy,” stated Johannes Escudero, Founder & CEO of RNG Coalition. “These numbers highlight the critical role that RNG is playing in decarbonizing the medium- and heavy-duty transportation sectors today.”
