Natural Gas Vehicles for America (NGVAmerica) and Coalition for Renewable Natural Gas (RNG Coalition) have announced that 64 percent of all on-road fuel used in natural gas vehicles in the calendar year 2021 in the United States was renewable natural gas (RNG).

Captured above ground from organic material in agricultural, wastewater, landfill, or food waste, RNG can produce carbon-negative results when fueling on-road vehicles like short- and long-haul trucks, transit buses, and refuse and recycling collection vehicles.
California Air Resources Board (CARB) data confirms that the annual average carbon intensity (CI) value of California’s bioCNG vehicle fuel portfolio in its Low Carbon Fuel Standard (LCFS) program was carbon negative and below zero at -44.41 gCO2e/MJ for the calendar year 2021.
The RNG used as a transportation fuel grew 13 percent over 2020 volumes, up 234 percent from 2017 levels.
NGVAmerica and RNG Coalition report that in 2021 a total of 610 million gallons of gasoline gallon equivalent (GGE) of natural gas were used as motor fuel. Of that, 390 million gallons (GGE) were from renewable sources.
Transitioning to renewable natural gas-fueled vehicles is the most affordable and immediate climate-positive change a fleet can make today. With current savings of up to US$2.60/gallon or more over diesel, fleets can slash annual fueling costs while virtually eliminating NOx and particulate matter emissions and decarbonizing their freighting operations, said Dan Gage, President of NGVAmerica.
RNG used as a motor fuel in 2021 displaced 3.8 million tonnes of carbon dioxide equivalent (CO2eq).
Renewable Natural Gas supply is growing. With 250 RNG facilities transforming waste into fuel, and another 237 facilities on the way, we are increasingly able to affordably offer consumers the opportunity to decarbonize with RNG – the cleanest of any fuel available today, said Johannes Escudero, Founder & CEO of RNG Coalition.
