RNG accounted for 64% of on-road NGV fuel use in 2021

May 8, 2022 |

In Washington, D.C., Natural Gas Vehicles for America (NGVAmerica) and Coalition for Renewable Natural Gas (RNG Coalition) report that 64% of all on-road fuel used in natural gas vehicles in calendar year 2021 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 data confirms that the annual average carbon intensity (CI) value of California’s bio-CNG vehicle fuel portfolio in its Low Carbon Fuel Standard (LCFS) program was carbon negative and below zero at -44.41 gCO2e/MJ for calendar year 2021(1).

RNG use 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 (GGE) (2) of natural gas were used as motor fuel.  Of that, 390 million gallons (GGE) were from renewable sources(3).
